Chatoyancy of a Satin Spar Sphere: the mineral selenite (satin spar) is often found with parallel fibrous crystalline structures that reflect light in luminous bands (chatoyancy) that appear to move as the specimen is rotated. Selenite fibers are also very clear and will act as a natural form of fiber optic transmission- the sphere looks transparent when the camera lens peers down the fiber bundle direction. ➡️ Follow the link in my profile for info on where to get a polished selenite sphere and

Gemstone Chatoyancy and Stars: illuminating gemstone cabochons reveals rays and stars where light is scattered by microscopic parallel crystal fibers of rutile (titanium oxide) or magnetite that grow within the different mineral species. These fibers grow to be in alignment along the axes of the crystalline structure producing the illuminated rays: 6 point star (synthetic red ruby-aluminum oxide with trace chromium), 4 point star (black diopside- calcium magnesium silicate), and a simple “tiger

Chatoyancy is light moving across structure. Tiger eye showing sharp bands of reflection. Cat eye golden petersite drawing a single line of light. Double-flash black gugan reflecting from layered surfaces. Light shaped by structure and pattern, not surface. Live at HardStuPH. #crystaltok #crystalsph #chatoyancy #tigereye #petersite

Chrysoberyl cat’s eye is a very rare and unique gemstone that allows the light to play across the stone in an effect called “chatoyancy” from the French word oeil de chat. This wonderful phenomenon is seen as the light passes across the stone resulting in a wonderful feature that will always make this ring stand out. Made in 18 carat gold in the early 1900’s, the elegant oval cabochon stone as well as its colour and of course the effect it displays, will make certain that this ring is always lov

Assay on Instagram: "🔮 One of the strongest Cat’s Eye effects we’ve ever seen. So sharp… it doesn’t just show one—it shows three. This gem doesn’t play around. The chatoyancy (that glowing line across the stone) is so strong, it splits into three distinct eyes under the light."
