Citrine is quartz generally occurring in a golden color. Citrine occurs naturally in Scotland and in the Ural Mountains of Russia. Much citrine available today is actually smoky quartz or amethyst that has been heat-treated to achieve its characteristic color.

Jasper is opaque chalcedony quartz that comes in a wide variety of colors and patterns, depending on the trace minerals present in the stone. Landscape jasper, which seems to show miniature earth scenes, and ocean jasper with its characteristic green swirls are both popular. Jasper was used for decorative and medicinal in many ancient cultures and the Babylonians believed it was beneficial to women's health.
