Description

Bi-color ametrine presents an attractive look when rough stones are carefully chosen to produce a stone that's as close as possible to half amethyst and half citrine. Rarely seen with a perfect half-and-half split, the exact proportions from stone to stone vary slightly, giving each stone a unique appearance. This ametrine gemstone coordinates well with either amethyst or citrine, as well as with complementary color stones.

Ametrine is a rare quartz containing both citrine and amethyst; it is created when a temperature gradient exists across the crystal during its formation. Colors range from medium-dark to bright orange in the citrine, and vivid purple to violet purple in the amethyst—larger stones present more saturated hues. Almost all ametrine comes from mines in Bolivia.

The octagon cut is a rectangle cut that features traditional faceting as well as step cuts. The table is larger on this cut, which both enhances the color and highlights the step cuts.
