Emeralds have been always among the most expensive colored minerals, a segment that includes rubies, sapphires and alexandrite. The market's need for high-quality analogues of emeralds has resulted in elaboration of the materials, which possess all the physical, chemical and optic properties of the natural stone - created gems. Experienced specialists from RusGems recrystallize low-quality natural emeralds which undergo a multiple-stage technological process to create an ideal gem using the hydrothermal method of growth. The structure of a recrystallized emerald is identical to the organic and can be identified only by certified gemological laboratories.
Specific features of synthetic crystal of Colombian Emeralds are:
- Bright color. Green stone with intensive blue tone of medium or low saturation. This stone has the color identical to the one of the Colombian analogue
- A set of impurities, which defines the structure and imperfections, is identical to the one of a natural Colombian emerald. Natural emeralds as well as HTE emeralds contain vanadium and chromium impurities
- Absolute correspondence between diagnostic properties of the HTE emeralds and natural Colombian emeralds. This means that it is extremely difficult to identify recrystallized material. For example, a well-known testing approach, which employs the Chelsea filter, helps to identify the emerald crystals of RusGems as the ones that are identical to natural Colombian emeralds
- Thus, it is impossible to distinguish the artificially created stone from the natural prototype based only on its color and visible flaws
