a GRA Certificate refers to a Gemological Research Association (GRA) Certificate, which provides an official evaluation and certification of a gemstone’s quality, typically focusing on diamonds or diamond alternatives like moissanite.
This certificate assesses various aspects of the stone, including:
- Carat weight (size of the stone)
- Cut (the quality and style of the stone's facets)
- Clarity (any inclusions or flaws within the stone)
- Color (how colorless the stone appears)
- Other characteristics, such as the origin of the stone
If you're purchasing a moissanite with a GRA Certificate, this document verifies the stone’s authenticity and quality, ensuring it meets certain industry standards.
