Our stones

Carnelian is a brownish red-to-orange variety of chalcedony that has been used in beads since the 5th millennium BC. Because hot wax does not stick to it, the Romans used it widely for engraved signet and seal rings, pressing their mark into wax to seal letters and important documents.

Goldstone is a manufactured material composed of tiny copper flecks suspended in glass, which give it a warm, glittering sparkle. Legend says it was discovered by accident by alchemist monks who were trying to make gold.

Labradorite is a smoky, quartz-like stone treasured for its remarkable play of color, known as labradorescence: iridescent flashes of peacock blue, gold or pale green that appear when light hits it from certain angles. According to an Inuit legend, the Northern Lights were captured in the rocks on the coast of Labrador, where the stone was first discovered.

Lapis Lazuli is a semi-precious stone prized since antiquity for its intense blue color, formed as limestone slowly turns into marble. Mined in Afghanistan since the 7th millennium BC, it adorned amulets and treasures across the ancient world, including the funeral mask of Tutankhamun. In medieval Europe, it was ground into ultramarine, the finest and most expensive of all blue pigments.

Denim Lapis Lazuli is a lighter, paler variety of traditional Lapis Lazuli, with a soft blue-jean color and noticeable white streaks of calcite. It shares the long history of classic lapis, but its gentler, faded-denim tones give it a more relaxed, everyday feel.

Larimar is a rare, semi-precious blue variety of the mineral pectolite, found exclusively in the Dominican Republic. Its color ranges from sky blue and turquoise to deep blue-green, with white marbling and wave-like patterns that resemble the Caribbean Sea.

Malachite is known for its rich green color and intricate banding. Ancient civilizations, especially the Egyptians, prized it for amulets, jewelry and cosmetics, and ground it into pigment for green paints and dyes. Many cultures believed it could ward off evil and bring good health.

Mookaite is a vibrantly colored jasper in shades of red, mustard yellow and cream, found primarily around Mooka Creek in Western Australia. Aboriginal Australians have used it for tools and ceremonial objects, valuing its unique beauty and its connection to the earth.

Moonstone is a captivating and mystical gemstone, admired for its soft, iridescent glow that seems to shift as light moves across its surface. It has been worn for millennia by ancient civilizations such as the Romans, who believed it was born from solidified rays of the Moon.

Mother of Pearl, also known as nacre, is an organic material that some mollusks produce as the inner layer of their shells, and the same substance that forms pearls. Strong, resilient and softly iridescent, it has been used for centuries in jewelry and decorative inlays.

Onyx is typically black but can also be found in white, red and green. Its rich, smooth appearance made it a favored material among the ancient Greeks, Romans and Egyptians, who used it for jewelry, amulets and intricate carvings.

Gilson Opal is grown in a laboratory from opaline silica in a yearlong process that replicates how natural opal forms, resulting in a strong, durable stone with the same intensity of color as natural specimens.

Peachy Opal is characterized by a warm peach background with flashes of orange, pink and gold, whereas Aqua has a clear aqua-blue background with green flashes and yellow shimmers.

Gilson Opal is grown in a laboratory from opaline silica in a yearlong process that replicates how natural opal forms, resulting in a strong, durable stone with the same intensity of color as natural specimens. 

Jelly Opal is characterized by a pastel background featuring small flashes of yellow, orange, pink and blue whereas Starry Opal is characterized by vibrant flashes of yellow, orange, pink and green. 

Gilson Opal is grown in a laboratory from opaline silica in a yearlong process that replicates how natural opal forms, resulting in a strong, durable stone with the same intensity of color as natural specimens.

Lilac Opal has a soft lilac background with delicate flashes of pink, violet and blue whereas Yellow Opal has a sunny yellow background with glowing flashes of gold, orange and green.

Opal Matrix is a porous, sandy host rock filled with tiny grains of precious opal, found largely in the Andamooka opal field of South Australia. Because the pale rock mutes the opal’s colors, cutters darken it with smoke or a burnt sugar solution, creating a dark background against which the bright flashes of color stand out.

Pink Opal is a common opal: it lacks the vibrant play of color of precious opal but comes in beautiful soft shades. It is found at Mooka Station in Western Australia, an area once covered by a vast inland sea, where pink and yellow opal occur together and are typically mined by small teams or families.

Porcelain is a ceramic material fired in a kiln at 1,200–1,400 °C (2,200–2,600 °F), where it partly turns into glass, making it uniquely strong and translucent. Its name comes from the old Italian porcellana, or cowrie shell: Marco Polo used the word to describe the pottery he saw in China, because its smooth surface resembled that of the shell.

Purple Jasper, also known as Burro Creek Jasper, is a distinct variety of jasper admired for its striking and rare purple and lavender tones. It is found primarily around Burro Creek in Arizona, an area rich in jasper and agate deposits that has long been a favorite among rockhounds and lapidaries.

Red Jasper is characterized by its deep, earthy red color. Ancient civilizations such as the Egyptians, Greeks and Native Americans valued it highly for amulets, talismans and carvings, believing it held protective and healing properties.

Rhodonite is a rose-pink manganese mineral, often laced with dramatic black veins, whose name comes from the Greek rhodon, meaning “rose.” First discovered in Russia’s Ural Mountains, it was known locally as orletz, “the eagle stone,” after the eagles that carried pieces to their nests, and it became a tradition to place it in babies’ cradles and give it to travelers for protection.

Snakeskin Jasper is a red and white banded variety of jasper, naturally colored by iron oxides, whose alternating layers create a pattern reminiscent of snakeskin. It comes from the Weeli Wolli Iron Formation in Western Australia, one of the largest iron deposits in the world, formed around 2.5 billion years ago.

Turquoise, known for its striking blue to green hues, has been treasured for millennia. Ancient Egyptians, Persians and Native Americans valued it for its beauty and protective qualities, and it was often considered a sacred stone believed to bring good fortune and healing.

UV Glow Opal is a common opal that ranges from bright white to buttery yellow and glows bright green under ultraviolet light. This fluorescence comes from tiny traces of uranium that dissolved into the silica as the opal formed.

Variscite is a rare mineral valued for its vibrant green color, which comes from traces of chromium or vanadium. It was first discovered in Variscia, the historical name of Germany's Vogtland region, but the most sought-after specimens come from the Little Green Monster Mine in Utah.
