GRA Certification

What Is GRA Certification — And Why It Matters To You

Select ShelbyCo Moissanite Pieces include a GRA Certificate of Authenticity for complete peace of mind.

What is GRA?

GRA (Gemological Research Association) is an independent gemstone grading authority that evaluates moissanite stones based on internationally recognised standards. Each certified stone is assessed for:

• Carat weight
• Cut quality
• Clarity grade
• Colour grade

Your certificate confirms that your moissanite matches the specifications advertised — no guesswork, no inflated claims.

What This Means For You

✔ Proof of Authenticity
Your moissanite is professionally graded and verified — not an imitation stone.

✔ Guaranteed Quality Standards
The certificate details the exact quality characteristics of your stone, so you know precisely what you’re receiving.

✔ Added Confidence When Gifting
Whether it’s an engagement ring, anniversary gift, or personal investment, certification provides reassurance that your piece meets premium standards.

✔ Transparency & Trust
We believe luxury should be backed by documentation. Certification ensures clarity and accountability.

A Smarter Alternative To Traditional Diamonds

Moissanite offers exceptional brilliance and durability — often exceeding the sparkle of traditional diamonds — at a fraction of the cost. With GRA certification, you receive the beauty and performance you expect, supported by verified grading.

Luxury should feel secure.

With ShelbyCo, it does.
