Earth-mined Bolivian ametrine weighing 12.09ct ETW in an oval rose cut, featuring slightly included clarity, natural purple and yellow coloration, and unheated character.

This ametrine displays the distinctive combination of amethyst's purple hues and citrine's golden-yellow tones. Its unheated character preserves its naturally occurring color distribution, while the rose-cut faceting creates an elegant arrangement of reflections that highlights the gemstone's contrasting colors.

Ametrine is a naturally occurring variety of quartz that contains both amethyst and citrine color zones within the same crystal. Its unusual coloration results from differences in the oxidation states of iron within the quartz structure. This combination of two familiar quartz varieties in a single gemstone gives ametrine a distinctive appearance that appeals to collectors and jewelry designers.

Bolivia is the world's principal commercial source of natural ametrine, particularly the famous Anahí deposit. Bolivian ametrine is recognized for its attractive purple and yellow color combinations, making geographic origin an important part of the gemstone's identity.

At 12.09 carats with dimensions of 16.8 x 13.5 x 10.0 mm, this ametrine offers impressive visual presence. Its substantial size and oval rose-cut shape make it particularly well suited for a custom statement pendant, where the contrasting colors and distinctive faceting can be prominently displayed. It also makes an appealing addition to a collection of larger faceted gemstones.

With a hardness of 7 on the Mohs scale, ametrine offers good scratch resistance for jewelry when handled with reasonable care. Its combination of generous dimensions, natural color zoning, and elegant rose-cut styling provides numerous possibilities for distinctive custom designs.
