Carat – A unit of weight measurement for precious stones. It is important not to confuse this with the other karat (American spelling) or carat, which is a measure of the purity of gold. ‘Carat’ is abbreviated to “ct.” One carat is equal to 1/5 of a gram (200 milligrams). Stones are measured to the nearest hundredth of a carat. There are a hundred points in a carat, so that a .10 carat stone can also be described as a 10 point stone. Smaller stones are most often referred to by point designations. An average one-carat round diamond usually measures approximately 6.5mm in diameter. This relationship of weight and size, however, is different for each type of cut and differs for other gems. Rubies and sapphires, for example, are both heavier than diamonds, so a one carat ruby or sapphire is smaller in size than a one carat diamond.

Magnetic – A recent innovation using powerful mini magnets. Other, more obscure, clasps include the Box and the Ladder.
Claw – A claw setting is one in which a series of metal prongs (called claws) holds a stone securely in a setting (the claws grips the stone just above the girdle of the stone), with no metal directly under the stone (it is an open setting). This setting lets light in under the stone, so this type of setting is usually used for transparent, faceted stones. The modern-day claw setting became popular in the 1800s.

Engrave – This is gouging out a design in metal with graver’s tools, or embellishing metal or other material with patterns using a drill. This was fashionable in mid-Victorian jewelry.

A U-shaped spring fits under the ear lobe and round the back of the ear to hold the earring in place. Claimed to be more comfortable than traditional clips as it does not grip so tightly, is lighter and not so bulky on the ear. Clip – A traditional hinged earring fitting for un-pierced ears. Continental – See Lever back. Hook fitting – Usually for drop earrings and also called a hook wire or safety wire fitting, these earring fittings hook through the ear and hang down behind the lobe.

The bead is removed, the pearl cleaned (to prevent deterioration) and the remaining hole filled with paste, wax or sometimes with another bead and then covered with a mother-of-pearl backing. Mabe pearls must only be used in closed-back settings. Also referred to as a half-pearl or cultured blister pearl.
