Carat: Unit of weight used the measure precious gem stones and diamonds.
Abbreviated “ct” or “c.” One carat is equivalent to 1/5 of a gram. A hundredth
of a carat is also called a point. Thus a .10 carat stone can be called either
10 points, or 1/10 of a carat. A one carat round diamond is approximately 6.5 mm
in diameter. This relationship of weight and size is different for each type of
gem stone. For example rubies and sapphires are both heavier than diamond, so a
1 carat ruby or sapphire is smaller in size than a carat diamond. (Karat with a
"K" is a measure of the purity of a gold alloy.)

on a piece of jewelry. Usually the item is layered with silver or gold.
Emerald: A deep green gemstone. Fine emeralds are among the most valuable
gemstones. Unlike diamonds and some other gemstones, flaws, or inclusions, are
common in emeralds, so their value is less affected by them than with other
precious stones like diamonds. The most highly prized emeralds are from
Columbia. A fine emerald is bright, vivid green, with the most valuable having a
slight blue cast to the bright green. Many emeralds used in jewelry are of
relatively low quality as they are often dyed or oiled to improve the color and
minimize the flaws. If an emerald appears to be very fine and lacking any flaws
it is most likely synthetic.
Emerald cut: Rectangular-shaped gemstone with boxed corners. An emerald cut
gemstone is elongated and octagonal.
Engraving: A technique in which metal is cut away to form a decorative design or
letters, done by either hand or machine, or by using a stamping tool or drill.

but subtle irregularities.
Estate Jewelry: By definition this term simply means “previously owned,”
although many people today have confused the term to be interchangeable with
Etching: To remove part of a surface by acid for a decorative effect. Usually
etching is done on a precious metal like silver or gold.
Eternity Band (Ring): Traditionally, this term refers to a millenniums old ring

used in fine pearl jewelry. They come in a variety of colors, including rose,
lavender and violet.
G (in color): When grading diamonds “color” refers to the absence of color in a
diamond. The rating scale begins at D – colorless - ending with Z. 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.
Garnet: A semi-precious stone found in many colors but usually in a dark,
crimson red, but can also range from deep red to deep purple to brown orange and
Gemstones: Diamond, emerald, chalcedony, agate, heliotrope; onyx, plasma;

jacinth, hyacinth, carbuncle, amethyst; alexandrite, cat's eye, bloodstone,
hematite, jasper, moonstone, sunstone.
Genuine: Used to describe or designate a true precious stone, as opposed to a
synthetic or “fake” version of the stone in costume jewelry. It is common to see
gemstone names when describing costume jewelry: amethyst, diamond, garnet,
emerald, ruby, sapphire. These words should not be interpreted to mean the
precious stones with these names. The terms are used only to describe the color
of the non-precious or synthetic stones. If the genuine stone is meant, it is
usually indicated with the word “genuine” in the description. This general rule
also applies to words for metals, such as gold, silver, copper and pewter.
Gilding: A process of covering fine jewelry or another artistic object with a
precious metal like gold or an alloy. Also referred to as plating.
Gimmel ring: A ring formed of two or more linked hoops, which fit together in a

Gold: A yellow or silvery precious metal that is prized for its beauty, purity
and brilliance. It does not oxidize or tarnish like sterling silver or most
other metals. Gold used in gold jewelry is usually alloyed with other metals
since gold in its pure form is very soft and pliable, and therefore would not be
durable for wear by itself. Gold purity is measured in Karats (Karats with a “K”
grade gold, Carats with a “C” measures the weight of diamonds and gemstones.)
The Karat marking system was not widely used until around the late 1800’s. The
karat number refers to the parts of pure gold per 24 in the alloy. For example,
14K gold jewelry is 14/24 parts pure gold, or about 58% gold. Many European and
other countries mark gold with a three-digit number indicating the parts per
thousand of gold. Thus gold jewelry is often marked "750" for 750/1000 gold.
(Equivalent to US 18K). In addition to various purities in gold jewelry, gold
also comes in many colors, including white, pink and green gold, in addition to
the familiar yellow gold.
Gold Filled: Abbreviated in jewelry descriptions as g.f. = lower in gold content
than 10 KT, usually 1/20 or 1/12 K. In this technique a sheet of gold is applied
to the surface of the jewelry. Most gold-filled jewelry is marked with the
fineness of the gold layer, and the part by weight of the gold. So a piece
marked "1/10 12K G.F." is at least 1/10 12K gold based on the weight of the
finished piece. In the U.S., gold filled pieces must be at least 1/20 by weight
to be classified as gold-filled.
Goldplate: A layer of gold applied to base metal, usually by electroplating.
Grain: Unit of weight for measuring diamonds and pearls. One grain is equal to
Gram Weight: The most common unit to measure the weight of jewelry. The gram
weight is the metal weight of a jewelry piece in grams.
Green gold: Gold that contains a high proportion of silver, but is not a
naturally occurring metal. The green color is produced by mixing 24 karat gold
with a blend of silver, copper and zinc.
Gypsy setting: A gemstone setting where the stone is sunk into the metal leaving
the top of the stone nearly level with the top of the metal surface.
H-I (in color): When grading diamonds “color” refers to the absence of color in
a diamond. The rating scale runs from D (colorless) to Z (a lot of color).
Though some color can be seen when an H-I diamond is graded, it appears
colorless when mounted and is commonly used in fine jewelry.
Hallmarking: A stamp on gold, silver or platinum by assay offices after the
metal has been tested and determined to contain the proper amount of precious
metals required by law. Common stamps on jewelry are 925 (indicating solid
sterling silver), 10K, 14K and 18K (indicating various gold purities).
Head: The prongs that hold a gemstone or diamond in place on a jewelry setting.
Herringbone: A silver or gold chain with small, slanted links that join to form
a flat chain.
Hidden Box Clasp: A necklace or bracelet closure that consists of a flat slip

Jade: A hard natural stone that has been treasured by the Chinese and Indians
for 7,000 years. Jade is made up of two different mineral species with similar
appearance: nephrite and jadeite.
Karat: Used to define the amount of pure gold found in a jewelry item.
24 karat (24K) gold is pure gold.
18 karat (18K) gold contains 18 parts gold and 6 parts another metal or metals.
14 karat (14K) gold contains 14 parts gold and 10 parts another metal or metals.
10 karat (10K) gold contains 10 parts gold and 14 parts another metal or metals.
(41.7% gold) 10k gold is the minimum karat designation that can still be called
gold by U.S. standards.
Lab Created: Gemstones created in a lab with exact chemical properties as the
natural gems. Also known as synthetic stones, they are usually far lower in proce than natural gemstones.

Mabe Pearl: A half sphere or domed pearl. Also called a blister pearl.
Matte Finish: A textured finish produced by brushing the metal surface to
produce tiny parallel lines. Today it is popularly used in platinum jewelry, and
sometimes referred to as satin finish.
Marcasite: An iron ore material, pyrite, which is set into silver or pewter
jewelry creating an antique jewelry look. The minerals marcasite and pyrite are
similar in composition but are actually different. True marcasite is not
suitable for jewelry making so “marcasite” jewelry usually uses pyrites
round-cut and polished, mounted in a rhodium-plated silver setting.
Mariner Link Chain: A bracelet or necklace chain made of thick oval links that
have a bar across the center.
Marquise Cut: A gemstone cut in an oval shape, pointed at both ends creating a

Mélange: Term for mixed diamond sizes weighing more than carat.
Mélée: Classification of diamonds weighing less than carat
Milanese Chain: Bracelet or necklace chain made of interwoven rows of small
links creating the look of mesh.
Mohs' Hardness Scale: The most common standard for rating gemstone hardness.
Developed by Friedrich Mohs, a German mineralogist, as an assessment of “scratch
hardness” by ranking 10 different stones from hardest to softest. His list
includes the following:
10. Diamond (Hardest)
6. Orthoclase Feldspar
1. Talc (Softest)
Because the numbers are based on properties of actual stones, they are not
equally distributed. So the difference between 10 (diamond) and 9 (sapphire) is
not equal to the difference between any other two numbers. Very soft stones
scratch more easily and some stones are too soft for jewelry.
Moissanite: A lab-created gemstone based on the structure of natural moissanite,
which is linked to meteorites. Similar in look to a diamond, but moissanite has
more brilliance, fire and luster than any hard jewel - including diamonds.
Mother of Pearl: The smooth iridescent interior surface on the inside of sea
shells and certain mollusks
Mounting: The metal frame or housing in which gemstones are set.
Nacre: The silky substance secreted over a “bead” to form a pearl. Layer after
layer of nacre builds up to form the pearl. When viewing a pearl in good
lighting, light travels through all the layers of nacre, and each microscopic
crystal reflects the light like a prism, creating an iridescent effect. The
thicker and more lustrous the nacre, the more valuable the pearl.
Natural Gemstone: A stone formed in nature, with no interference from humans.
The opposite of synthetic or lab-created gemstones.
Navette Cut: Gemstone shaped like a boat or oval with two pointed ends. Also
called marquise cut.

hardness. Primary sources include Australia, Brazil, Guatemala, Honduras,
Indonesia, Japan, Mexico, Russia, Nevada and Idaho.
Open-work: A piece of jewelry that has open areas. This ring setting is designed

by purposefully inserting a tiny mother-of-pearl bead. Pearls, like other gem
stones come in a variety of shapes and forms. A blister pearl is a pearl that
forms attached to the shell. A half-dome shaped pearl is a mabe (pronounced mah-bay)
pearl. Irregularly shaped pearls are called baroque.
Pendant: Any article or ornament suspended from a chain or necklace worn around
Peridot: A green semi-precious gemstone that can range in color from bright,
vibrant greens to yellow-green to olive green to deep green. On the Mohs’ scale

Rhodium: A metal that is part of the platinum family, but not precious metal.
Silver, gold, and even base metals are often Rhodium plated to give them the
shiny, mirror-like look of platinum. Rhodium plating makes silver jewelry less
vulnerable to tarnishing and easier to care for.
Rolo Chain: A silver or gold chain with thick round or oval links.
Ruby: A red precious gemstone. The birthstone for July. Color can range from a
hot pink to deep, blood red. Lab-created rubies are often attempted to pass for
genuine – a genuine stone can usually only be deciphered by an experienced
gemologist. Fine, genuine rubies can be worth more than diamonds.
Sapphire: A precious gemstone in the corundum family of stones, most commonly
blue but they also come in a range of colors from white to orange to green to
pink. A corundum gemstone is red, it is referred to as a ruby, but any other
color in inexpensive jewelry are referred to as sapphires. Some sapphires are
synthesized, so it takes an expert to determine if a sapphire is natural.

multi-stone diamond earring, rings, pendants and bracelets. The grade signifies
that inclusions cannot be seen by the naked eye but can be seen under 10x
Silver purity: Like gold, pure silver or fine silver is relatively soft and
pliable. Because of this, fine jewelry can be easily damaged if created from
pure silver. As a consequence, silver is commonly alloyed with other metal,
usually copper, to create a stronger precious metal. Unlike gold, but like
platinum, silver purities are expressed a percent of purity. The most regularly
seen silver purities are: 958 or 95.8 percent pure silver, and 925 or 92.5
percent pure silver (stamps could also say 92.5 and .925). 925 silver is known
as sterling silver.
Slide: A type of pendant or fastener that slides onto a chain or fabric ribbon

Square Setting: A diamond or gemstone setting with four prongs that hold a
stone, usually a square or princess-cut gemstone.
Stack Ring: A ring designed to be “stacked” – or worn in multiples - on one
Sterling Silver: 925 parts silver, or 92.5 percent pure silver. The most common
type of silver used in fine silver jewelry because it is not only luxurious, but
also durable and relatively easy to care for.
Stud: A simple earring made from one ball or gem stone attached to a straight
post with no dangling parts.
Synthetic Gemstone: A gemstone created by humans in a lab. Synthetic stones
mimic the structure, color and texture of natural stones making it sometimes
difficult to tell a synthetic from a genuine gemstone. These stones are usually
far cheaper, making gemstone jewelry more attainable for some.
Tahitian Pearls: The highest quality black pearls, Tahitian pearls exhibit
luster, nacre and color variations rivaled by none. They have a gentle, velvety
luster and often exhibit a strong iridescence. Color can range from deep gray to
peacock blue to metallic green and everything in between.
Tanzanite: A precious gemstone from the zoisite family. Colors naturally occur
in shades of blue, green, yellow, pink, brown and khaki but virtually all
gemstone quality crystals are heat treated to produce the popular shades of
sapphire blue, amethyst and blue violet. On Mohs’ scale of hardness, tanzanite
is 6.5-7. Named for the stone’s prime mining source: Tanzania.

Turquoise: A natural, semi-precious gemstone found in desert. The brown or grey
streaks in turquoise are caused by the matrix, or “mother” stone, from which the
turquoise is mined. Interesting and intricate patterns are considered to add
beauty to the stone. Persian turquoise is the only type of turquoise that
usually does not have a matrix. Modern turquoise "stones" that appear very shiny
and absolutely flawless are probably manufactured and of less value. Geuine
turquoise can appear in colors ranging from sky blue to green.
Ultrasonic Cleaner: A machine that cleans jewelry by vibrating a solution at an
ultra-high frequency. Capable of cleaning tiny cavities on or inside fine
jewelry without scratching the surface, but can damage soft or brittle
gemstones. Ultrasonic cleaners should never be used to clean pearls, coral and
turquoise jewelry or any beaded jewelry strung on string or silk.

VS (clarity): VS clarity diamonds are of superior quality and frequently used in fine jewelry. The grade signifies that minor inclusions are difficult to see, even under 10x magnification.
White Gold: Created by alloying yellow gold with palladium, nickel, zinc, and/or silver, white gold is often selected as a less expensive and easier-to-maintain alternative to platinum. It is often plated with rhodium to give a platinum-like sheen.
Yellow Gold: In its natural state gold comes in varying shades of yellow. Relatively pure when initially mined, gold is usually alloyed with copper, zinc, and/or silver when used in jewelry making.
