About GRA Certification

Gemological Research Association (GRA) Certification

At Rubielle, every certified moissanite piece is accompanied by an independent GRA certification.

GRA (Gemological Research Association) is a recognised gemological authority that evaluates and grades moissanite stones according to established standards. Each certified piece includes an individual grading report detailing carat weight, cut, colour, clarity, measurements and a unique identification number.
This is not a marketing claim. It is documented proof.

 

• Not All Moissanite Is Equal
  

The rapid rise of moissanite has led to a surge in uncertified, misrepresented and falsely marketed stones.
Many pieces are sold as “certified” without legitimate documentation. Some stones are inaccurately graded. Others are not moissanite at all.
Low prices often come at the cost of transparency.
If a stone does not come with independent certification, you are relying solely on a seller’s word.

 

 

• At Rubielle, We Do Not Rely on Claims. We rely on verification.

Every certified moissanite piece includes:
• An official GRA certificate
• A unique report number
• Independently documented grading
No assumptions. No vague descriptions. No shortcuts.

 

 

• Know What You Are Buying
  

Moissanite is an exceptional stone — when it is genuine, graded and properly represented.
Certification protects your investment.
Integrity protects our name.
Luxury is not only about brilliance.
It is about accountability.
