which makes for a very hard plastic.
Baguette: A narrow, rectangular-cut stone
Bail: The connector at the top of a pendant, enabling the pendant to hang
from a chain or jumpring
Baroque: Bold, ornate, heavy looking ornamentation. When the term is used
to describe a pearl, either real of fake, it means that the shape of the pearl
is irregular
Basse-taille: (pronounced bass-tie) This describes a technique of applying
glass enamel to a metal surface that has been engraved deeply enough to hold
the enamel when heated, with sides high enough to keep the enamel colors separate.
Bezel: A setting for a stone that has a collar instead of prongs to secure
the stone
Blue Topaz: A topaz that is light brown or colorless when mined but turns
a vivid blue when exposed to heat. Blue Topaz is an alternate birthstone for

Bog Oak: Wood that was preserved over thousands of years in the bogs of Ireland,
which was hard enough to be carved and used as jewelry; popular during Victorian
times.
Book Chain: A Victorian style of chain made in gold, gold filled , and sterling
silver, in which each link is a rectangular, folded piece of metal resembling
a book. They were often elaborately engraved and had large lockets attached.
Box Setting: A stone enclosed in a box-shaped setting with metal edges pressed
down to hold the stone in place; also referred to as a "gypsy" mounting
Brass: An alloy made up of roughly half copper and half zinc which has a nice
yellow color.
Brilliant cut: The standard round brilliant consists of a
total of 58 facets: 1 table, 8 bezel facets, 8 star facets and 16 upper-girdle
facets on the crown; and 8 pavilion facets, 16 lower-girdle facets, and usually
a culet on the pavilion, or base. Although the brilliant style was devised
to give maximum brilliancy and fire, many stones cut in this fashion do not
have ideal proportions or angles for that purpose. Modifications of the round
brilliant include such fancy shapes as the marquise, half moon, pear shape
and many others. See also "Round
Cut".
Briolette: A pear-shaped stone that is faceted
Brooch: A large pin; an ornamental piece of jewelry with a pin and clasp to
be attached to clothing, from the French word "broche", meaning "to
pierce" or an object/weapon made for piercing.
Bronze: A very dense and heavy alloy of 60% copper and 40% tin. It has a dull
brown color and is not favored for jewelry because of the weight.
Brushed Finish: Brushed finish, also known as “satin” finish,
is a texturing technique that can be used on metals where a series of tiny
parallel lines are scratched onto the surface with a wire brush or polishing
tool.
