As mentioned on the FAQ & Policies Page, Rob buys gemstones according to what strikes his
artist's eye. All the stones are real.

Some items in the catalog are available set with a number of different stones. On this page,
you will find information about all of the stones that appear in Rob's jewelry. Availability is
noted in the individual descriptions of each product in the catalog.

As a rule, pieces are set with dome-cut stones. Faceted stones may be specially ordered. Standard
stones are offered in silver; premium stones can be ordered set in silver for an additional cost. However,
due to cost of the stones we highly recommend that the piece be ordered in white gold if a white color
is preferred, due to durability and wearability. We carry many varieties of fancy tourmalines and other
gems for special order and custom work only.

If you would like a piece with a particular stone which is not listed on this page, it may be possible
to special order it. Please feel free to contact us with any questions.

The Stones

Amethyst Deep violet color; most amethysts are from Africa or South America. It is a member of the quartz family.

Garnet A deep red stone, due to its magnesium and iron content; garnets rarely exhibit inclusions. Garnets range from green to yellow to orange to red; Pyrope and almandine are the popular red color.

Emerald A green type of beryl, emeralds contain traces of chromium and vanadium in their crystals. Premium stone.

Pink Tourmaline Of the durable elbaite variety of tourmaline, the pink color comes from manganese content. Tourmaline is the most varied of colored gems with regard to color. Many shades are available, both of green and pink tourmaline. Premium stone.

Green Tourmaline Light to medium green, due to chromium, iron or vanadium content. Premium stone.

Blue Topaz Also called London Blue Topaz; varying between light blue and medium blue. Blue topaz is a treated stone, irradiated and heat-treated depending upon color with almost no exception.

White Diamond All diamonds are priced on request. All sizes, grades and shapes can be special ordered. Premium stone.

Champagne Diamond Natural stones with a brownish-gold color; an excellent complement to gold rings and pendants. Most have visible inclusions, as it is the nature of colored stones. Premium stone.

Blue Sapphire Blue sapphire takes it color from its iron and titanium oxide content. Sapphire is a heat-treated stone (to enhance the color) for the most part, at the present time. Premium stone.

Moonstone One of the best-known and most valuable types of feldspar, moonstone is translucent with an iridescent surface. We use Sri Lankan Blue-White whenever possible.

Aventurine A green quartzite stone made of interlocking grains of quartz and small mica crystals.

Carnelian Reddish-orange; carnelian is a type of chalcedony which gets it color from the stones' iron oxide content; may be uniform or slightly banded.

Citrine Citrine is a yellowish member of the quartz family.

Ruby Varying shades of red; the more chromium the stone contains, the deeper the color. This is also a known treated stone in today's market, again to enhance color. Premium stone.

Blue Agate All agates are dyed; blue is only one variation of the coloring.

Onyx Also a dyed agate, black with a shiny finish.

Green Agate Another dyed agate.

Peridot Olivene (rich olive-green) in color. Premium colored stones are extremely rare, but are available priced on request. Premium stone.

Aquamarine Blue beryl ranging from light blue (almost colorless) to a rich blue almost to the color of the Hope Diamond; however, these are extremely rare and expensive. Most stones that we handle are a medium sky-blue.

Blue Diamond Irradiated in order to create the color, as natural blues are very rare and expensive. Most are included and priced accordingly.

Blue Chalcedony Offered as a premium and custom stone, occasionally in gold.

Indicolite Tourmaline Deep blue tourmaline; offered as a premium or custom stone.

Rutile Quartz Quartz with inclusions caused by other minerals, i.e. magnesium and titanium, within the stone. Usually gold, yellow or reddish orange in color, with fibres or needles creating intricate patterns, almost like human hair.

Tourmalated Quartz Clear quartz with black tourmaline crystals inside the stone.

Peitersite Tigers-eye quartz; clear quartz with gold-yellow highlights and sometimes with brown and/or blue markings.

Tsavorite Garnet Deep, emerald-like green garnet, owing its color to its chromium content.

Iolite
Taking its name from its color, iolite is at the blue end of the purple spectrum, whereas amethyst is at the red end. Main sources are Burma, Brazil, Sri Lanka, India and the Malagasy Republic. Also known as "Water Sapphire."

Red Lace Agate

Blue Moonstone Heat-treated moonstones that are very pale with a bright, distinctly blue sheen when viewed at an angle.

Pearls
In Chinese mythology, pearls were created by the moon, which was responsible for their milky-white color. In truth, white fresh- and salt-water pearls are often bleached to achieve uniform color. White is not the only option, however - cultured pearls come in white, gold, yellow, champagne, pink, peach, lavender, gray and black. Irradiation, dying and heat treatment can produce yellow, green, blue, purple, gray and black in freshwater and Akoya cultured pearls. Most South Sea and Tahitian pearls are not enhanced in any fashion.

Because pearls are created by living organisms, they are organic and sensitive to chemicals and acids, and since they contain water, they may dehydrate and crack if continually exposed to arid conditions. Contact with perfume, hairspray, abrasives, solvents and nail polish remover should be avoided.

Baroque pearls are pearls that are non-spherical in shape.

Inclusions are liquid or gas bubbles, healing cracks or foreign crystals inside the stone; inclusions
are not necessarily faults, as they attest to the genuineness of the stone. Back to top.
