With our Emerald sets, the natural emeralds are sourced directly from Columbia.  We have included a natural emerald, oiled natural emerald and an impregnated natural emerald.  In these emerald sets, you may see two and three phase inclusions, growth tubes, intersecting veils, angular growth zoning, and the characteristic spectrum which will help you define the natural gem from a synthetic and imitation Emerald in this set.  All the sets come with a Flux Melt Emerald and Hydrothermal Emerald and a Garnet-topped doublet (a favourite in many practical gemmological exams).Buy high quality emerald gem sets at an affordable price.
