ALROSA Diamond Inspector detects colorless and near-colorless* polished:
- True natural diamonds.
- Enhanced/man-treated natural diamonds**.
- Non-diamond imitations, including moissanites, cubic zirconia, rhine-stone/rock-crystal, spinel, amethyst etc.
- Synthetic diamonds grown by HPHT or CVD methods (further lab-testing needed***).
Stones could have various cutting shapes**** and carat weight ranging from 0.03 to 10 carats.
* — near-colorless relates only to yellow color D-K and doesn't relate to blue, green, pink and other low-intensive colors;
** — this result is almost 100% evidence of laboratory processing (ennobling) of diamonds (only in very rare cases, natural diamonds could be slightly ennobled by nature (not man));
***- some rare natural diamonds (less than 1.5-2%) could have the same optical properties as CVD, HPHT-synthetic diamonds. A set of expensive lab-equipment could define the authenticity of diamond with 100% level of confidence;
**** —the device is designed for the analysis of diamonds, the shape of which has a flat facet with a circular area of more than 1.5 mm in diameter (more than 3.2 mm2).
