RARE Ametrine (aka Bolivianite) set in solid gold pierced earrings

These are unique gem earrings purchased directly in Cochabamba, Bolivia. Amethyst is a purple quartz. Citrine is a yellow quartz. Quartz that displays bands of both purple and yellow is known as ametrine. Gem-quality ametrine is sourced from only a single site in Bolivia so it is rare and desirable, and is also called "Bolivianite" or "Boliviana" by locals. This could be a family heirloom and no one else will have these earrings! So special.
