January = Garnet
February = Amethyst
March = Aquamarine
April = Diamond
May = Emerald
June = Pearl
July = Ruby

Bracelet - An item of jewellery worn on the wrist. They can be of plain precious metal, decorated designs of precious metal or set with stones. Common types of bracelets are: chain-link bracelets such as curb and figaro; rope bracelets; herringbone bracelets; charm bracelets; gate bracelets; fancy-link bracelets; and tennis bracelets.
Brilliance - This is the sparkle that is seen in a gemstone when it is held up to the light. It is caused by the reflection of “white”light back from a gemstone, both from its surface and from within. The more “white” light reflected back, the greater the brilliance. The brilliance of a gemstone is influenced by its cut, its proportions, its polish, its transparency and its physical and chemical make-up.
Brilliant Cut - This round cut is the most common and popular style of cut for diamonds, and many other gemstones. This is because it has been designed with 57 carefully proportioned facets to maximise the amount of light reflected and refracted by the gemstone. Below is a diagram showing a brilliant cut diamond and its facets:
Brushed Finish - A textured finish on jewellery, where a series of tiny parallel lines are scratched on the surface of the metal.

C
Carat - This is often abbreviated as “ct” and has two separate meanings:
1) It is the unit of weight measurement for gemstones. A carat is divided into points, and there are 100 points in a carat, so 25 points is equal to ¼ carat. It is one of the four characteristics that influence the value of a diamond.
2) It is the term used to describe the purity of gold alloy used in an item of jewellery. With pure gold being rated as 24 carat, the most common standards of gold alloy used in jewellery are:
- 9ct gold, which 37.5% pure gold (or 375 parts pure gold and 625 parts other metals).

Couture - Highly fashionable clothing and jewelry created by leading designers.
Cabachon - A smooth and dome shaped stone.
Carat - This is often abbreviated as “ct” and has two separate meanings:
1) It is the unit of weight measurement for gemstones, whereby one carat is equal to one-fifth of a gram. A carat is divided into points, and there are 100 points in a carat, so 25 points is equal to ¼ carat. It is one of the four characteristics that influence the value of a diamond.
2) It is the term used to describe the purity of gold alloy used in an item of jewellery. With pure gold being rated as 24 carat, the most common standards of gold alloy used in jewellery are:
- 9ct gold, which 37.5% pure gold (or 375 parts pure gold and 625 parts other metals).
- 14ct gold, which is 58.5% pure gold (or 585 parts pure gold to 415 parts other metals).
- 18ct gold, which is 75% pure gold (or 750 parts pure gold and 250 parts other metals).
- 22ct gold, which is 91.6% pure gold (or 916 parts pure gold and 84 parts other metals).
The carat of gold used in an item of jewellery is illustrated in its hallmark (see hallmark).
Chain - A length of connected loops, links, rings or beads used to create a necklet or bracelet. There are various types of chain, with the most popular being: the curb link, flat round or oval links; the belcher link, round or oval links that don’t lie flat; the figaro link, a series of alternating short and long links in different combinations; the box link, solid square links; the snake chain; and the rope chain.
Channel Setting - This is where the stones are held side-by-side between two strips of precious metal. Channel set gemstones sit flush with the mounting so are less likely to be caught and snagged.
Charm Bracelet - A bracelet which has, or can have, small charms attached to its links.
Chevron Setting - In this style of setting, “V” shaped claws hold the gemstone in place. It is used at the points of marquise cut gemstones.
Clarity - One of the four characteristics that influence the value of a diamond. A diamond’s clarity is determined by the degree to which it is free from naturally occurring inclusions, or “nature’s fingerprints”. The number, type, colour, size and position of these “birthmarks” can affect the value. However, many of these inclusions are actually invisible to the naked eye and require magnification under an eyeglass before they can be seen. The fewer the inclusions, the rarer the diamond and thus the more valuable it is.
Clasp - Any type of attachment that is used to join one end of a piece of jewellery to the other, usually bracelets and necklets. The most commonly used clasps in jewellery are: the bolt ring; the lobster claw; the box clasp; the bar and ring clasp; and the fold-over clasp.
Claw - A precious metal prong used to hold a gemstone in place.
Claw Setting - A series of precious metal prongs, or “claws”, designed to hold a gemstone securely in place whilst allowing maximum light to reach it.
Clip-on Earrings - Earrings that are designed for people who do not have their ears pierced. The earring is held in-place on the lobe by a clip.
Cluster Ring - A ring which has a collection, or “cluster”, of gemstones arranged in a decorative design. Common cluster patterns are the “daisy cluster”, which resembles the flower of a daisy, and the “boat cluster”, which resembles the shape of a boat as viewed from above.
Colour - One of the four characteristics that influence the value of a diamond. While most diamonds appear white, many of them actually display hints of colour barely discernible to the naked eye. The closer a diamond is to colourless, the rarer and more valuable it is. Diamonds with a strong pure colour are extremely rare and called “fancies”. Some of these colours that can be found in diamonds include pink, blue, yellow, green and orange.
Creole Earring - A hoop style earring, often elongated, for pierced ears. They are frequently highly decorated and have a secure bar and clip fastener
Cross - A pendant in the shape of a cross. It can be plain or patterned metal, or set with gemstones.

Cubic Zirconia - A hard and relatively inexpensive stone, created in laboratories and often cut to resemble a diamond. Although most commonly colourless, it is available in different colours such as pink and purple.
Cultured Pearl - See pearls.
Cut - One of the four characteristics that determine the value of a diamond, and the only one that can actually be influenced by man. When a diamond is cut well and all the facets are in proportion, light will reflect from one facet to another and disperse through the top of the stone, resulting in a display of brilliance and fire. When the facets are not in proportion or when the diamond is cut too shallow or too deep then light is not reflected and refracted adequately and the brilliance is not as great. It is this poor cutting that can severely decrease the value of a diamond. The style of cut, such as baguette, emerald or marquise, is a matter of personal taste and not so important in influencing the value of a diamond.
D
Diamond melee - Not to be confused with diamond chips, these small diamonds are full cuts, containing all 58 facets, and are frequently used in fine jewelry as accent diamonds. The word melee refers the diamond's weight, which is less than 1/5 of a carat.
Drop Earring - Sometimes referred to as a "dangle earring", this design includes any earring with hangs below the earlobe.
Diamond - The most valuable and treasured of all gemstones. Its name refers to its hardness, nothing is comparable so it is virtually imperishable, hence the saying “a diamond is forever”. Diamonds are the birthstone for April. Only about 20% of all diamonds mined are good enough to be used in jewellery. A diamond’s value is directly linked to its quality which is measured by 4 characteristics, its: carat; cut; colour; and clarity (known as “the four C’s”).

Engagement Ring - A gemstone set ring used to symbolise a strong commitment of love. Diamonds are the most popular choice of gemstone because of their value and traditional symbolism of lasting love, with the solitaire design being the favourite choice. An engagement ring is traditionally worn on the third finger of the left hand, because it was believed that the vein from this finger ran directly to the heart.
Eternity Ring - A gemstone set ring often used to show a long-term commitment of love. Although often bought as an accompaniment to the wedding and engagement ring, it can be worn on its own as a dress piece. Eternity rings come in several distinctive designs:
1) The full eternity, which has gemstones set around the entire shank.
2) The half eternity, which has stone set on the upper half of the ring.
3) The wishbone, which has the stones arranged in a wishbone shape on the upper half of the ring.

Though some color can be seen when a G diamond is graded, it appears colorless when mounted, thus it is commonly used in fine jewelry.
Gold - The most malleable, and most ductile of all metals, gold by itself is too soft to be used in it natural state to be used for jewelry making, and it is commonly alloyed with copper, nickel, or other metals. Unlike silver it does not oxidize or tarnish.
Gemstone - Any crystallized mineral structure (natural or synthetic) used in jewelry making. This includes all precious and semiprecious stones but excludes all types of plastics and glass.
Garnet - Garnets are most frequently reddish brown in colour, butthe garnet is actually part of a family of different coloured minerals with the same chemical make-up.

Girdle - The narrow band around the widest part of a polished or faceted gemstone. It separates the crown and the pavilion.
Gold - A precious metal, yellow in its natural state but its exact colour depends on the amount and type of impurities. It is a very soft and malleable metal and when used in jewellery it is alloyed with other metals to increase its hardness and durability.

Hallmark - This is the authorised stamp from an assay office which is found on items of gold, silver and platinum. The hallmark indicates the authenticity and standard of the precious metal and is awarded after independent tests by the official assay offices at London, Birmingham, Sheffield or Edinburgh.
Hardness - This is an important quality of a gemstone because it influences how hard-wearing it is. A gemstone’s hardness is measured by how resistant it is to being scratched. It is measured using the Mohs scale of hardness, whereby one substance is harder than another if it can scratch it (see Mohs Scale).

When you look at the gemstone surrounded by the disc, it gives the illusion of it being a larger stone.
Inclusion - A natural feature within gemstones, inclusions are particles of foreign matter or impurities which were trapped within the gemstone when it was formed, because of this they are often referred to as “nature’s fingerprints”. The inclusions found within diamonds are generally carbon specks, a remnant of the carbon which was turned into diamond through a combination of extreme heat and pressure. Most inclusions are microscopic in nature, but their presence can affect the value of a gemstone if they affect its clarity, brilliance, sparkle and fire.

Mohs Scale - A loose scale measuring a mineral’s hardness in relation to other minerals, based upon the ability to resist scratching. It is used to classify the hardness of gemstones. It was developed by the German Friedrich Mohs, in 1822, and he used 10 minerals, ranking them 1 to 10 based upon their ability to scratch each other. Whereby, each mineral will scratch the one below it in the scale, but can only be scratched by those above it. The scale is as follows:

Opal - A gemstone made of hardened silica gel. It is the birthstone for October. There are two types of opal:
1) Precious Opals – these opals have a rainbow-like iridescence which changes as the stone is angled under light, known as opalescence. There are two groups of precious opals. The first are white, or milky, opals which are the most commonly used for jewellery. The second are black opals, whose basic colour is dark grey, dark blue, dark green or grey-black.. Dark black opals are very rare.
2) Fire Opals – these are named after their orange colour. They do not opalesce and are best when clear and transparent.

Pear Cut - A teardrop shaped cut, commonly used for pendants and drop earrings.
Pearl - These are organic gemstones which grow within molluscs, particularly oysters and mussels. They are formed when a foreign body, such as a small stone, gets trapped inside a mollusc’s shell. The mollusc then secretes nacre, a lustrous substance, to coat the object and reduce the irritation that it causes. Over time thousands of layers of nacre coat the foreign body and a pearl is formed. This process takes up to 7 or 8 years to produce a pearl large enough for use in jewellery. The most valuable pearls are large, symmetrical, naturally produced and have a shimmering iridescence. Pearls vary in colour from white, through white with a hint of colour (usually pink), to brown, grey and even black, depending upon the mollusc and the water in which it lives. There are several types of pearl:
1) Natural Pearls - occurring naturally with no human interference.
2) Cultured Pearls - where a piece of mother-of pearl or a small bead is inserted artificially into a mollusc to start the process in a controlled way. Most pearls found in jewellery today are cultured pearls.
3) Freshwater Pearls - produced by molluscs living in rivers and lakes. They are quite irregular and elongated in shape. They are popular in jewellery because of their shape and excellent value.
4) Seed Pearls - tiny pearls used in smaller items of jewellery.
5) Blister pearls - this is where the pearl is attached to the inside of the shell.

Pendant - A hanging ornament on a chain.
Peridot - A gemstone with a distinctive green colouring. It is the birthstone for August.
Pierced Earrings - Earrings designed for wear in ears that are pierced. A post or wire is passed through the earlobe.
Platinum - Of the three precious metals, platinum is the rarest and most valuable. It is silvery-grey to white in colour and, unlike silver, it does not tarnish when exposed to the atmosphere. It is slightly more dense than gold and about twice as dense as silver. To make it easier to use, the platinum used in jewellery is an alloy containing 95% pure platinum and 5% other metals (or 950 parts platinum to 50 parts other metals).
Point - A point is another way of measuring a diamond’s weight. A carat is equivalent to 100 points, therefore half a carat is 50 points, a quarter carat is 25 points and so on.

Ring size - The measurement of how large a ring needs to be to fit securely on a person's finger. Traditionally the average ring size of a woman was 6 and a man's 10, but this has been slowly increasing.
Reflection - When light bounces back off the surface of something, such as a diamond. When combined with refraction it produces a diamond’s fire.
Refraction - When light is bent as it enters a gemstone, such as a diamond. A stone’s cut and clarity can influence its refraction. When combined with reflection it produces a diamond’s fire.
Rhodium - A white metallic element. A rhodium finish is usually applied to white gold to give it greater and brighter whiteness.
Ring - A piece of jewellery worn on the fingers or, sometimes, toes. They are used for dress and fashion purposes or to show a commitment of love. Some common gemstone set rings are: solitaire rings; eternity rings; cluster rings; two-stone rings; trilogy rings; and pave rings.

Safety Chain - A fine chain attached to a necklet, bracelet or brooch which provides extra security in case the catch opens.
Sapphire - A gemstone from the same corundum mineral family as the ruby, and the birthstone for September. In fact, any gem quality corundum stone that is not red is a sapphire. Although traditionally blue in colour, sapphires can also be colourless or vary in colour from yellow, through green, to pink. Blue sapphires are the most commonly seen in jewellery, and range from pale blue (Sri Lankan sapphires) to a very dark blue, almost black, with the most valuable being those that are a clear and deep blue. Pink sapphires, whose colour comes from the chromium which give ruby its colour, are also very desirable, especially when set in white gold.
Satin Finish - A textured finish on the surface of precious metal which has a soft lustre rather than a shine. It can be produced by brushing, sandblasting or chemically altering the surface of
