AMETRINE SIGNIFICANCE: Ametrine is one of nature's most remarkable gemstone phenomena - a single quartz crystal displaying both amethyst (purple) and citrine (yellow) color zones. This bi-color variety occurs naturally when temperature variations during crystal formation create different oxidation states of iron within the same stone. Bolivia's Anahi mine produces virtually all commercial ametrine worldwide. TREATMENT TRANSPARENCY: Heat treatment and irradiation to enhance or create color in quartz varieties is standard industry practice. Natural color ametrine can occur, but distinguishing natural from treated color using current gemological methods is scientifically challenging. These enhancement methods are permanent, stable, and universally accepted in the international gem trade. SIZE RARITY: Ametrines over 50 carats with strong purple-yellow contrast and perfect transparency are exceptionally rare in commercial markets. Most ametrines show subtle color transitions or are under 20 carats. This 54+ carat specimen with dramatic bi-color display represents museum-grade material suitable for elite collections or high-end jewelry commissions. FANCY CUT ADVANTAGE: The specialized fancy cut is specifically designed for bi-color stones to maximize visual impact of the purple-to-yellow transition. Unlike standard cuts, fancy cutting creates optimal facet windows that showcase the dramatic color phenomenon - ideal for appreciating nature's artistry in this unique quartz variety. VERSATILITY: With excellent hardness (7 on Mohs scale) and substantial size, this ametrine is ideal for statement cocktail rings, dramatic pendants, or museum displays. The combination of size, bi-color drama, and transparency makes this specimen suitable for luxury jewelry at accessible pricing compared to other bi-color gemstone varieties. Clarification on "See Comments" treatment disclosure: When a certificate states "See Comments" under treatments, this indicates standard industry practice. Heat treatment or irradiation to enhance color in quartz is universal and has been practiced for centuries. This enhancement is permanent, stable, and fully accepted in the international gem trade. We sell all stones with full transparency and competitive market pricing. ===================================================================== For a detailed Certificate Report Please copy and paste this link in your Browser: https://app.scaglobal.com/verify?report=TH25G114898&date=10%2F07%2F2025&pin=4188&tenant=888888 Or Scan the QR code in the images. ===================================================================== Please read the below Information's and terms for your better understanding.
