Greetings !
A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks and occasionally organic materials that are not minerals are also used for jewelry and are therefore often considered to be gemstones as well.
GDI Laboratory helps you with certification after verifying the product with laboratory tests and let's you relax with the product after being checked and tested.
A gemstone certificate is a document issued by a gemological laboratory that has been licensed. Some gemstone certificates only confirm the weight and authenticity of the gemstone. Others, especially in the case of diamonds, will specify color and clarity grades.
