Here is a pretty stone! These concave Ametrines are extremely popular, and sought after when we have them in stock. The color is primarily a light yellow, but there is a spot of purple in the center. Ametrine is a naturally occurring purple and yellow bi-color variety of Quartz that is formed by a unique twin law ("Brazil Law Twinning") where two separate individually colored crystals are intergrown to form an alternating "radiation" pattern of purple (Amethyst) and yellow (Citrine) triangles when viewed down the c axis. The two colors are oriented based upon their position inside the crystal to create the famous bicolor gemstones. This stone has been concave cut to produce that lovely radiant pattern of the flash. We have set countless numbers of these concave cut stones into jewelry and they are stunning when set. Enjoy!
