From a gemological standpoint the peridot s structure is the reason its sparkle is so compelling, peridot is gem quality olivine, a magnesium iron silicate that crystallizes in the orthorhombic system, this structure produces measurable birefringence and a refractive index range roughly between 1.65 and 1.69, the combination of relatively high refractive index and defined birefringence allows well proportioned facets to act as efficient mirrors, when light enters the stone it is refracted and internally reflected along complex paths before exiting as bright flashes of light, the mixed brilliant cut has been tailored to exploit these optical properties, brilliant facets create rapid scintillation while the step facets near the pavilion preserve color saturation, excellent polish and precise facet junctions maximize light return and crispness of sparkle, peridot s vitreous luster and intense color intensity enhance perceived brilliance even though its dispersion is more modest than that of diamond, the result is a lively, multidimensional sparkle that reads as brightness and depth on the wrist or in a display, for an educated buyer this 31.68 carat Burmese peridot offers a superior combination of natural color, top tier clarity, expert cutting and untreated origin, qualities that translate into lasting aesthetic value and strong collectibility, The Natural Gemstone Company is pleased to offer this rare specimen with full provenance and gemological transparency.
