Synthetic Emerald Refractive Index. the lennix synthetic emerald, currently n~anufactured in france, is a dark green, moderately transparent to translucent. birefringence of natural emerald ranges from 0.004 to 0.010, while synthetic emerald will hardly ever go over 0.004. refractive index, or ri is one of the most important signatures of a gemstone. The fluorescence of malossi synthetic emeralds might hint at. 230 rows for gemologists, refractive index and double refraction (birefringence) serve as important clues for identifying gems. synthetic emerald of russian manufacture. emeralds exhibit double refraction, meaning they refract light in two different patterns. in contrast, synthetic and treated emeralds often display inclusions that are visual evidence of their artificial. national gem lab is providing unique gemstone identification chart to search easily from our search bar to find refractive index, hardness & specifc gravity. table 1 shows average values of refractive index, birefringence, and density for colombian emeralds, other world deposits and some synthetic emeralds. the refractive indexes of the synthetic gems ranged from 1.560 to 1.580 while the natural gems had refractive indexes from 1.571 to 1.598. The following table lists these values for a variety of stones found in jewelry and gem collections. measuring a stone’s refractive index (ri) and specific gravity (sg) are the first steps. This article provides a general discussion of the technique used togrow these stones. synthetic emeralds can usually be distinguished from natural gems by the presence of characteristic inclusions.
