Calcite – One of the World’s Most Versatile Minerals Calcite is an abundant and diverse mineral on Earth. It’s used in everything from cement and chalk to toothpaste and sculptures, surrounding us in ways we rarely notice. But practical uses aside, calcite is also a stunning gemstone for jewelry. This mineral appears in crystal clusters, massive formations, or banded patterns. Some varieties exhibit strong fluorescence under ultraviolet light, while others display optical effects like double refraction, where objects viewed through the crystal appear doubled.

Expertly cut to accentuate their natural beauty, Gallery TCR is ready to ship these stones to jewelers, collectors, and gemstone enthusiasts across the U.S. Shop now if you’re looking for a high-grade gem to set in jewelry or to expand your collection. Do you know the difference between “facet rough” and “faceted gemstone”? Facet rough refers to raw, uncut stones, while faceted gemstones are cut and polished with flat surfaces (facets). Simply put, you can enhance the brilliance, fire, and overall appearance of a facet rough by transforming it into a faceted gemstone through gem-cutting. The art of faceting dates back to the 15th century, forever changing the way gems reflect light. Our collection includes an array of faceted gemstones cut with techniques that follow the precision and artistry of centuries-old craftsmanship. Our vibrant sapphires, dazzling amethysts, fiery garnets, and other faceted gemstones for sale add brilliance to engagement rings, statement necklaces, and custom jewelry designs. Expertly cut to maximize color and light reflection, you won't be disappointed in our curated selection. These stones also make excellent additions to any connoisseur’s private collection.

Cabochons – Subtle Elegance, Polished and Ready to Set A cabochon is a precious or semi-precious gemstone with a polished domed surface. Rather than sparkle like a diamond or faceted gem, the rounded cut enhances color, reflection, or translucence over a domed surface. Our cabochons for sale never stay in stock for long because our buyers know they're receiving high-quality, well-cut pieces with stunning colors and patterns in a variety of shapes and dimensions. Did You Know? The word "cabochon" derives from the French word "caboche," meaning "small dome." Cabochons have been a staple in lapidary projects and jewelry design since ancient times. For example, Egyptians, Mesopotamians, and Greeks used the technique to adorn jewelry, masks, sculptures, and ceremonial objects, as they believed certain gemstones held magical and protective powers. Unlike faceted gemstones, cabochons emphasize color, pattern, and texture without relying on light reflection. This cutting style works best on opaque and translucent stones, as it brings out details like banding in agates, chatoyancy in tiger's eye, or the deep glow of turquoise and jade. Several other materials can be made "en cabochon," except diamonds. From vibrant agates to radiant opals and bold turquoise, each cabochon in our collection has exceptional quality and unique character. Shop now if you're crafting bespoke jewelry, creating decorative accents, or adding to your private collection. Gallery TCR is proud to carry one of the finest selections of cabochons in the United States, in stock and ready for delivery.

Agate – One of the Oldest Stones Used in Jewelry Agate is a variety of chalcedony, a fine-grained (cryptocrystalline) form of quartz.

Fluorite – Vibrant Colors, Infinite Creative Possibilities Fluorite, or fluorspar, is a mineral found across the globe in various geological settings. Its vivid fluorescence under ultraviolet light, which inspired its name, is why it’s visually striking and high in demand among lapidarists, jewelry makers, and collectors. Fluorite typically forms over millions of years through hydrothermal processes. In some cases, it also forms alongside other minerals like calcite, quartz, sulfides (like galena and sphalerite), as well as other fluorine-bearing minerals like topaz.

Scientists named the phenomenon of fluorescence after this mineral when they first observed its vivid glow under ultraviolet light. Ancient civilizations also carved fluorite into ornaments, and today, industries rely on it for optics and cutting-edge technology. Fluorite’s smooth textures and stunning colors are perfect for creating custom rings, pendants, or statement pieces. Collectors love its cubic structures and vibrant tones, while artisans enjoy its workability for carving and shaping.

Jaspers – Earthy and Vibrant Stones for Collectors and Creators Jasper is a patterned or solid type of cryptocrystalline quartz, meaning the crystals are so small they look like a dense, compact mass. It has excellent polish, is low maintenance, and is durable enough for all jewelry uses and other artistic creations. These stones, available here at Gallery TCR, are often shaped into cabochons, occasionally carved, and rarely faceted. Did You Know? While the red jasper stone is the most well-known variety, jasper has many other types. Bloodstone, Yellow, and Green are examples of other popular colors, while Leopardskin, Mookaite, and Ocean are sought-after patterns. Some are also “not true” jaspers. For instance, the Kaleidoscope jasper is actually a microcrystalline quartz, which contains tiny quartz crystals visible under a magnifier instead of a uniform mass. The leopard jasper also isn’t a genuine jasper but a chalcedony like fire agate and onyx. Found in unique formations throughout the world, jasper is ideal for creating custom jewelry. Various forms of this material are also made into decorative items, including but not limited to vases, ashtrays, and bookends. Physical properties of jasper: • Color: Wide range of red, yellow, green, and multicolored patterns • Luster: Smooth, polished surfaces with a waxy sheen • Transparency: Opaque • Hardness: Mohs 6.5–7, durable for wear and carving Jasper has been valued throughout history for its aesthetics and practical uses.

Azurite – Deep Blues from Arizona's Historic Mines Azurite is a copper carbonate hydroxide mineral with a characteristic deep blue to violet-blue color. Some compare its color, known as "azure," to the deep blue ocean or evening skies above desert landscapes. Speaking of desert environments, here at Gallery TCR, many of our azurite specimens for sale are from Arizona mines, which have produced some of the finest azurites in the world. Azurite forms in copper-rich areas, often alongside malachite, chrysocolla, and other secondary copper minerals. High-grade azurite from Arizona (a.k.a.

It’s also high in demand among in-the-know designers and lapidarists because of its rarity and ability to add a sense of je ne sais quoi to jewelry and ornamental pieces. Gem silica properties: • Color: Bright blue to vivid green • Luster: Waxy to vitreous • Transparency: Translucent to opaque, depending on the specimen • Hardness: Mohs 7 Interesting details: Gem silica forms under very specific conditions in copper-rich environments, making high-quality specimens extremely limited.
