Ethically Sourced Gems

There are hundreds of beautiful gems, but unless they can be ethically sourced [ES], lab-created [LC] or are from a fair trade [FT] supplier, they aren't used in Sulusso jewelry. We are uniquely skilled at tracking down a beautiful and ethical gemstone. Here are some of the most popular gemstones available.

Provenance, Gemstones & Our Sustainability Profile:

Fine art is verified and valued in part based on its provenance. Provenance in defined as both the place of origin and/or earliest known history of something. It provides authentication of a work of art.

Until now, it is has been uncommon, with the exception of rare and historical pieces, to provide ‘documents of provenance’ for jewelry.

At Sulusso, however, we like the idea, and know you do to. Every Sulusso custom piece is accompanied by our unique sustainability profile, or provenance.

Diamonds with Provenance: Beyond Conflict-Free
Minimum purchase: 1 carat

These diamonds are obtained through the most progressive and ethical sources known.

We excel beyond Conflict Free and the common 4C’s of cut, color, clarity and carat to include Origin. These diamonds come from legitimate sources that can disclose origin and cutting center practices. Our partners pay visits to the manufacturers and polishers and are in contact with organizations that conduct independent 3rd party verification of the mining practices.

Knowing where your diamond was mined and cut is one of the most important factors when determining the true value of a diamond. Ensuring that the people doing this work were treated well and paid fairly with good working conditions is even more significant.

Everyone involved in this process deserves respect. By purchasing a diamond from an ethical seller you help to improve the standards not just of the diamond industry, but you also increase the quality of life of the people involved along the way.

Ethically Sourced Gems

Alexandrite - The color-change properties coupled with the fact that it is quite rare over 2 carats, makes this an exceptional and valued gem. Alexandrite changes color in different lighting from deep greens, purples, blues and reds. First discovered on the birthday of the Czar of Russia, Alexander II, it was once considered to bring good fortune. [FT, LC]

Amethyst - A lilac or purple variety of quartz, which is one of the most widely found minerals in the earth's crust. Created by iron impurities in crystalline quartz, amethyst is very closely related to citrine and can at times be found in the same crystal. Revered by ancient Greeks as a talisman, Amethyst was thought to inspire courage and contemplation. [FT]

Aquamarine - Best known for its sky-blue color, aquamarine was in fact named for its sea-green hue. It was once believed to keep sailors safe and guard against storms at sea. A variation of the mineral beryl, aquamarine can appear blue when viewed from one angle and colorless from another. [FT]

Citrine - A member of the quartz family, citrine is closest to amethyst in composition. Its golden color is created by iron impurities in clear crystalline quartz. The ancients considered citrine to be a gift from the sun and was considered a symbol of warmth and affection. [FT]

Diamond - The most highly prized of all gems, valued for its exceptional brilliance and fire, diamond is most popular in its pure colorless form. This is far from the only color diamond is found in, with shades of yellow, green, blue, pink, red and even black being found in nature. These different shades are caused by impurities, for example, nitrogen in yellows and browns, or boron in blue diamonds. Diamonds are the hardest of all minerals, formed under enormous pressure and high temperatures. [ES, LC]

Emerald - Fine quality emeralds are among the world's most enchanting gems. Because of the extremely unique conditions under which an emerald grows, even top-quality emeralds will likely have some inclusion. The Incas and Aztecs worshipped emerald as a holy stone and the Maharajas of India believed the gem brought luck and restored health. [ES, FT, LC]

Garnet - Its name is derived from the Latin word for pomegranate, though with colors ranging from greens and oranges to reds, pinks and purples, it is far more diverse than just the well known red. It was once believed to have healing properties, particularly with regard to blood diseases. [FT]

Moissanite - Fifty thousand years ago, a meteorite crashed into the Arizona desert, scattering tiny fragments for miles. Enveloped in the meteorite fragments was a mineral discovered in the 19th century by Henri Moissan. This mineral was later to be called Moissanite, a nearly clear, very pale yellow-greenish gem. In 1998, Charles & Colvard was able to recreate moissanite in a laboratory in sizes that allow this brilliant gem to be used in jewelry. (Naturally occurring moissanite crystals are too tiny.) [LC]

Peridot - The gem-quality form of the mineral olivine, peridot has an olive green color. Originally called topaz by the Greeks and Romans, peridot has been mined for over 3500 years and was first discovered off the coast of Egypt in the Red Sea. The Egyptians believed that the gem sweetened dreams and revealed insights.

Ruby - Famed for its blood red color, ruby is the only color sapphire with a unique name. Like sapphire, ruby is the second hardest gem behind diamond. Ruby's color is caused by the presence of chemical impurities chromium and iron. Depending on their content, the color can vary from pinkish to purplish to brownish red. Most rubies available on the market have been artificially enhanced to be deep red, a color ruby that is extremely rare in nature. [FT, LC]

Sapphire - The name given to every color of corundum except red, sapphires are found in a rainbow of colors including yellow, pink, green, orange, white and blue. If blue is the most well known color sapphire, then "padparadscha," the name given to a very special pinkish orange colored sapphire, is one of the rarest. Found in Australia, its name means "lotus colored." Blue sapphires have often been chosen for engagement rings as an enduring symbol of loyalty and trust. [FT, LC]

Tanzanite - Boasting a uniquely sensual appeal, tanzanite is a pale bluish-purple gem that was unknown until 1967 when it was discovered by Massai herdsmen. To date, the only source of tanzanite remains the hills of northern Tanzania near Mount Kilimanjaro. [FT]

Topaz - The name Topaz comes from the Sanskrit word "tapas," meaning fire. The gem was once thought to fuel matters of the heart and to sharpen the wit of the wearer. Topaz is found in a variety of colors including white, yellow, orange and brown. Blue topaz is not naturally occurring, but rather is the result of irradiating topaz. [FT]

Tourmaline - This fabulous stone shows the greatest range of color of any gemstone. Some crystals even occur with multiple colors, such as "watermelon tourmaline," which is found with a mix of pink and green. Legend tells of tourmaline's power to attract friends and lovers, while protecting the wearer against bad decisions and danger. [FT]

Zultanite - A rare, ethically sourced gem, zultanite is mined exclusively in Turkey and distributed by a single supplier. This unique color changing gem turns from sage green to champagne to pale raspberry in various lighting. The color is consistent throughout its rough, so any zultanite piece, old or new, can always be matched with another zultanite gem. [ES]
