3.42 ct SERPENTINE – CANADA

Serpentine Serpentine is a mineral that most people recognize as a common rock-forming material, but for those of us who hunt for the extraordinary, it holds a breathtaking secret. I have always been drawn to the diverse textures of this subgroup, but nothing prepared me for the "Angel Wings" found in certain Russian material. These specimens possess a delicate, feathery, and shimmering silver-green chatoyancy that is unbelievably beautiful—looking more like celestial silk than solid stone. While Serpentine is usually reserved for carvings or cabochons, I felt compelled to facet these rare, gem-grade sections. The result is a gemstone that captures a soft, ethereal glow, transforming a humble mountain mineral into a piece of wearable art that seems to flutter with light. The Heritage & Discovery Historical Significance: Serpentine has been used by humanity for millennia, prized by ancient Romans as "lapis nephriticus" for its supposed protection against sorcery and venom. Historically, its name is derived from the Latin serpentinus, meaning "serpent rock," due to its mottled green appearance that resembles the skin of a snake. Beyond its decorative history, Serpentine is geologically significant as a marker of "serpentinization"—a process where water interacts with ultra-mafic rocks from the Earth's mantle. It represents the profound chemical transformation that occurs when the deep earth meets the hydrating forces of the crust. Discovery: As a broad subgroup of minerals (including Antigorite, Lizardite, and Chrysotile), Serpentine has been known since antiquity. However, the specific discovery of gem-quality, chatoyant "Angel Wing" material in Russia represents a modern high-point for the species. Found in the Ural Mountains, these specimens are a testament to the unique metamorphic conditions of the region, which allowed for the growth of exceptionally fine, parallel fibers that create the shimmering effect I find so irresistible. Important Mines: While Serpentine is found globally—from the historic "Precious Serpentine" mines in Afghanistan to the massive deposits in Pennsylvania and California—the Russian deposits in the Sverdlovsk Oblast of the Urals are unparalleled for aesthetic brilliance. I also have a deep respect for the "Williamsite" variety from the United States, which offers a translucent, apple-green hue that rivals fine Jade. For our vault, I prioritize the Russian chatoyant material because its "wing-like" structure is a phenomenon you simply won't find anywhere else. Mineralogical Profile Description: Serpentine is a group of hydrous magnesium iron phyllosilicates that crystallize in the monoclinic or orthorhombic systems. It sits at a 3 to 5 on the Mohs scale, depending on the specific variety, making it a soft and tactile stone. It is characterized by its greasy, waxy, or silky luster. The "Angel Wing" effect is a result of extremely fine, fibrous inclusions that reflect light in a sharp, chatoyant band. When I facet this material, I must align the pavilion facets perfectly with these fibers to maximize the shimmer. Unlike the common, opaque green rock, gem-quality Serpentine is often translucent to nearly transparent, offering a depth of color that ranges from pale lime to deep forest green. It is a dense, "tough" mineral despite its low hardness, making it a joy to polish to a mirror-like finish. Chemical Formula: (Mg,Fe,Ni)₃Si₂O₅(OH)₄
