VERBAL PRE-GRADE &
EVALUATION
If you’re considering investing in a piece of jewellery or a diamond, it is essential to have the piece evaluated to ensure you are getting what you paid for. With so many fakes on the market, a verbal pre-grade and evaluation will give you piece of mind and assurance that what you’re buying is real.
AOBUT US
Our aim is to break the monopoly and restriction of the existing interest groups within the scope of the law, so that consumption can return to reason and let the gem return to its original source. Take your own way and let others follow.

Take your own way and let others follow.
