Finding fine Ametrine is not especially difficult. Finding Bolivian material of this size and quality is another matter entirely. Stones approaching 145 carats with attractive color, flawless clarity, and strong cutting have become increasingly difficult to source, making examples such as this genuinely uncommon in today's market.
This remarkable Ametrine weighs 144.56 carats and measures 45.46 x 24.09 x 21.02 mm. The elongated oval shape provides an impressive presentation, allowing the Purple and Yellow colors to reveal themselves across a substantial crystal. The flawless clarity and excellent brilliance give the gemstone a bright, clean appearance, while the cutting has been carefully executed to make full use of the material's natural potential.
Large Bolivian Ametrine has always attracted collectors, but examples combining this size, clarity, and overall quality are encountered far less frequently than many buyers realize. This is the type of gemstone acquired not because it is needed, but because opportunities like it rarely come twice.
A gemstone chosen with intention, not impulse.
One portion of the crystal grew in conditions that favored amethyst color center formation. An adjacent portion grew in conditions that favored citrine aggregate formation. The result is the sharp boundary between the two color zones. Learn more about Ametrine.
