Glossary of Jewellery Terms, Part 2, F~Z
Continuing our Glossary of Jewellery Terms from Facet to Vintage, we bring you a quick easy reference guide to commonly used jewellery (or jewelry!) expressions. The first part of our glossary, A to E, can be found here.
Hint: Words in red are defined elsewhere in our glossary!
Facet A facet is a small flat polished surface cut into a gem to enhance its light refraction and add that dazzling element of sparkle.
A multi-faceted gem showing the sparkle from the carefully placed cuts.
This is a French word meaning imitation. Rhinestones and cubic zirconia are faux diamonds, and faux pearls may be made out of glass or mother-of-pearl. There are many other materials used to make faux gems, and some are so good they're difficult to differentiate from the real thing! Filigree Filigree, traditionally, is a way of working jewellery from fine wire thread and solder, creating delicate lacework patterns, but in modern costume jewellery terms filigree is often cast in a mould to give the same look.

Freshwater pearls are a natural organic gemstone produced in the shells of freshwater oysters and molluscs. They're slower growing than saltwater pearls but can grow much bigger, and often have irregular off-round shapes and grooves and whorls.
This strand of freshwater pearls shows the naturally occurring whorls and grooves - every pearl is unique!
Gem / Gemstone A natural gemstone is a precious, or semi-precious mineral crystal stone which is cut and polished to form a jewel. Advances in science in the 19th Century developed ways to reproduce and artificially create faux gemstones for use in costume jewellery, making jewellery more affordable for all. To learn more about gemstones see our alphabetical series of Gemology articles.
The wonderful range of colours and textures are clear to see in this selection of different mineral and crystal gemstones.
Intaglio Intaglio refers to the art of engraving or carving an image into a gemstone, much like a cameo in reverse. The advantage of intaglio over cameo is that the image is below the level of the stone and so remains protected from chipping, abrasion or erosion. Karat Karat (not to be confused with the gemstone weight measure, carat) refers to the purity rating of gold: pure gold is 24 karat. Gold is a soft metal so sometimes it is mixed with an alloy to make it more durable. Gold labeled 18 karat is 18 parts pure gold to six parts alloy, and 14 karat gold is 14 parts gold to 10 parts alloy (it always adds up to 24!). You can find out more in our blog "About Platings, Your Jewellery's Finishing Touch".

Lacquered A lacquer is a protective coating applied to jewellery to protect it from tarnish, or to protect the wearer from an allergic reaction. Jewellery that tarnishes easily, like silver, is often coated with a thin layer of lacquer to keep it bright and sparkly in the store, but the lacquer soon wears off with use. If you've ever bought a silver comb, or brooch and thought it felt a little like plastic this is because of the protective lacquer. Lapidary / Lapidarist Lapidary relates to the art of cutting or engraving a gemstone. A skilled gemstone cutter is also known as a lapidary, or more commonly now as a lapidarist to distinguish the art from the artist. Marquis / Marquise This is a method of cutting a gem into an oval with pointed ends, with an aspect ratio of 2:1 (length:width). The cut was first commissioned by King Louis XV of France who wanted a gemstone reminiscent of his mistress's (the Marchioness Madame De Pompadour) mouth! Also known as the Navette cut.

Mother-of-Pearl The mother of a pearl is the mollusc it grew within, and mother-of-pearl in jewellery terms relates to the colourful and lustrous nacre lining the shell. The lining can be flaked off in sheets and is often used to add shimmer to pendants and earrings.
The mother-of-pearl nacre has formed a thick cream and green layer in this shell, but different molluscs can produce mother-of-pearl in many different colours.
Nacre Nacre is a natural substance produced within oysters and molluscs. It forms the lining of the shell (mother-of-pearl), and is also what pearls are made of. When an irritant enters the shell of a mollusc, the mollusc immediately begins coating it in layer upon layer of nacre as a defence, and the result is a pearl! Pave Pave refers to a way of setting gems very close together and all at the same height, like cobblestones on a pavement. Their placement should be close enough together to make it hard to see the stone's mounting.
The pave set crystals create a stunning frame for these larger single gems. Earrings available from Alyssum Jewellery.
Pear Cut A way of cutting gemstones into the shape of a pear, or teardrop, with one end wide and round and the other end pointed.
Simple pear cut crystals are a classic and timeless look in jewellery, and these faceted pear cut clip-on earrings are available in many colours from Alyssum Jewellery.
Pearl A naturally occurring organic gemstone produced in the body of a mollusc, such as an oyster or mussel. Different molluscs can produce pearls of different colours and sizes, with some molluscs producing perfectly round pearls, and others producing pearls varying from off-round to puddle shaped. The main pearl varieties are Akoya (saltwater), Freshwater, South Sea and Tahitian, and they can be found in naturally fished molluscs and farmed molluscs (cultured pearls).
Pearls can be perfectly round or baroque (irregularly shaped), smooth or ridged and pitted, and come in several natural colours as seen in this picture.
Pendant A pendant is a ornament, decoration or charm that hangs from a chain around the neck, wrist or ankle. Pendant is from the Latin 'pendere', which means to hang down.
A single solitaire makes a stunning pendant, as in this 5 carat cubic solitaire pendant from Alyssum Jewellery.
