Named after the Sicilian River, Achates is formed from crystallization of volcanic rock. This fairly hard stone comes in a multitude of colors.
Traditionally said to bring luck and have many supernatural powers, this stone is usually found in Brazil and Uruguay. Part of the Quartz group, its color is a translucent purple.
This stone is said to have a harmonizing effect when in close contact to the body. It is also believed to encourage patience and soothe anyone in emotional turmoil. It is sourced in the Caribbean islands.

Coral can live up to three thousand meters below the seas around Taiwan and Japan, the Red Sea and Australia. Coral is produced by the smallest life forms which settle at the bottom of the ocean over a vast period of time. Coral can appear in a multitude of beautiful red shades, hence its name. Tateossian does not use endangered coral but only authorized farmed, nursery coral.
All crystal Tateossian products are made with Swarovski® Elements.
A widely used material within the RT collection. It is produced with specialized cold setting techniques, in order to create and build resilience and durability.
Fibre Optic Glass
This is one of the RT collection’s signature materials. It is produced from a fusion of millions of transparent fibers, effective for transmitting light. These are then injected with a variety of colors, hand-cut and polished into the desired shape. This is a very precise and labor-intensive technique, whereby the material is embedded, flush into the metal, to create an evenly finished surface. On other occasions, combinations of fiber optic glass colors are inlayed together to create interesting patterns before being flush into a cufflink. Both of these processes are carried out entirely by hand.
Fresh Water Pearl
A Fresh Water Pearl is formed in a mollusk that lives in fresh water, rather than salt water. Freshwater pearls come in various pastel shades of pink, peach, lavender, plum, purple and tangerine; as well as white and black.
Garnet is found in a variety of colors, most commonly in burgundy. In ancient times, many travelers wore the stone for protection, as it was believed it became illuminated at night.
The most malleable and ductile of all metals. Due to its softness, gold is often alloyed with other base metals. The carat is the indicator of the amount of gold present in an item/piece, with 9ct being the lowest amount and 24ct being the highest. Gold is of yellow color when in mass, although when finely divided it can be found in shades of black, ruby and even purple. It is found in sea water, although even in these modern times, no economic process has been designed to extract it from its source. The primary use of gold throughout the world still remains currency, considered so valuable that we measure all other values by it.
From the Greek, translated as ‘blood’. This is because when it is cut, the resulting coolant is a shade of red. In ancient times, shiny varieties were used as mirrors; it was also periodically used as mourning jewelry. If cut thinly, Hematite is transparent and reddish.
In pre-historic times, this was used for arms and Instruments, because of its hardness. In more recent times, it was also viewed by some colonies as more precious than gold. Colors vary from Purple to Green.
It comes in a combination of red - fancy and picture types. Its hardness allows the stone to be widely used, particularly in some types of mosaics. It is also said to obtain a variety of properties, from bringing the rain to strengthening the stomach.
This material is named after Labrador, the North American place in which it was first discovered. Its flash of iridescent color is defined as ‘labradorescence’ - it changes color depending on the angle of light refraction.
A signature material in the RT and Tateossian collections. Most leathers used are chosen from the finest options stemming from Italy.
Marble is metamorphosed limestone, composed of fairly pure calcite (a crystalline form of calcium carbonate, CaCO3). It is available in various shades, from green to red.
Mother of Pearl
This is produced from calcium carbonate, from the lustrous lining in the shells of sea substances such as pearl oysters and mussels. This lining occurs in tones of milky white.
Colors available are Blue, Pink and white.
Formed by layered deposits of limestone, the name translates from the Greek word meaning ‘fingernail’. Onyx is black and occurs in parts of Africa, Argentina and Mexico.
Deriving from the Greek word meaning ‘uncertain’, this stone comes in a variety of shades of green and is sourced in Burma, Australia and Brazil. This is a relatively soft stone.
All RT products are rhodium plated. Rhodium is a precious metal, deriving from the platinum family. Rhodium plating allows the product to have a hard, corrosion-resistant, silver-like coating. Its finish is highly polished and, most importantly, non-tarnishing.
Often crackled, named after its color. The smaller pieces can be worked into cabochons, whereas the larger pieces can be faceted. The best quality is found in the Malagasy Republic.
Rutile or titanium oxide (ti02) is a mineral that typically forms in long, thin needles. Rutilated Quartz is a beautiful stone, produced by large inclusions of golden or red rutile needles in clear quartz. The formation of this stone occurs due to high temperatures and pressure. Quartz (Si1O2) and Rutile (T102) are in stable (liquid) state but as temperatures cool down and pressure eases, the two separate, with Rutile crystals becoming trapped inside the Quartz crystals. Currently, the vast majority of Rutilated Quartz is mined in Brazil and is found in most gem-producing countries.
A malleable material, which can often be found - along with copper, lead and gold - in rocks. It is most commonly found in Mexico, Canada, Peru and the United States. The most outstanding feature of silver is its luster, which - when untarnished - can give a brilliant white shade. In ancient times, silver was valued more highly than gold. Its name comes from the Anglo-Saxon word Seolfer but it’s also related to the German word Silber and the Dutch word Zilfer. Its chemical symbol, Ag, derives from the Latin word for silver, argentum. Sterling silver contains 92.5% silver with the remainder being copper and a nominal amount of other base metal.
Often confused with a variety of different stones, Smoky Quartz is transparent, and at times includes streaks of white. This stone is found worldwide.
This stone’s name refers to the sodium content within the stone. Sodalite comes in many varieties of blue. The most important deposits are found in Bahia, Namibia and India.
Part of the Quartz group, brown iron gives the stone its golden yellow color. It has a silky texture, and when cut into a cabochon, produces a shine reminiscent of a cat’s eye.
The name derives from an ancient island in the Red Sea, Topazos. The most valuable color is pink, though it’s most commonly available in yellow. It is mostly mined in Sri Lanka, Burma and Russia.
Occurring in dense forms, the name translates as ‘Turkish stone’. Polishing the stone makes the color more intense.
