Supplier: Tourmaline, ruby, emeralds, sapphires crystal
Generally found in an area close to the gold town of Shakiso in the southern part of Ethiopia, the beauty of the emeralds is exceptional. As with any gem deposit, Ethiopia produces emeralds with a wide range of quality. Much of the material is a commercial grade, often heavily included with black mica crystals. However, some truly amazing gems have come from this deposit as well. The top-quality stones from Ethiopia are grass green or green with a hint of a blue hue, and have no need for� oil enhancement. Our stones are even more exciting because of their saturation. Our bright, saturated greens are comparable with the stones from the mines of Colombia. Some dealers describe the color as \"glowing\" or having a \"neon\" quality and compare it to Paraiba tourmaline in this regard.
