Vintage and contemporary costume jewelry is often accented with or covered in rhinestones. The stones can be glass, crystal or acrylic plastic. Vintage rhinestones were produced in Austria, Czechoslovakia, France, Japan and Germany.

Types of Rhinestones

* Cabochon stones have flat backs and smooth, rounded tops with no facets. They may be any color, including black, and may have the depth and color variations of opals

* Faceted stones are cut or molded, and have multiple flat surfaces that reflect light. Probably the most common type of rhinestone.

* Opaque stones are not transparent or foil backed, and are often made to simulate turquoise, coral, jade and onyx. They look more like rocks than gems.

* Cameo stones have a design raised on the top surface.

Rhinestone Cuts

* Machine Cut rhinestones are the most brilliant. Made of glass crystal, they are cut and polished so that the edges are sharp and crisp, making them sparkle. Swarovski rhinestones, produced in Austria, are the most valuable and prized. Think of how a cut diamond looks.

* Table Polished stones have just the top facet, or "table" of the rhinestone polished. They won't have the sparkle of machine cut rhinestones.

* Fire Polished rhinestones are molded glass stones that are polished using heat, vibration or a combination of both. They are often brightly colored, but do not sparkle like the machine cut nor do they have the sharp finished edges.

Backs

* Flat Back rhinestones have a flat even underside, and are often applied with adhesive to other materials such as fabric, crafts and nails. You may see them used in inexpensive costume jewelry.

* Faceted Backs are pointy with faceted undersides are also used in crafts and clothing

* Foiled Backs have underside of the rhinestone coated with a metallic foil, similar to that used on mirrors, which causes light to be reflected back and giving the stone sparkle. Foil backed rhinestones are probably the most common type

* Unfoiled Backs have no foil on the bottom of the stone, allowing light to pass through it, giving it a precious gem appearance.

* Domed backs are rounded on the underside, not faceted or flat.

A popular finish for vintage rhinestones is Aurora Borealis. Introduced in 1955, it's a thin metallic finish applied to the top of the stone that gives it an iridescent glow and color changes when moved around in the light.

It's all a matter of taste, and there are so many variations of size, shape and color or stones, to say nothing of styles of jewelry, that every bracelet, necklace, pin or pair of earrings you collect will have unique features and sparkling appeal.
