How to Spot High-Quality Moissanite: A Buyer’s Checklist

Moissanite has become a top choice for those looking for a brilliant, affordable, and ethical diamond alternative. However, not all moissanite stones are created equal. If you want to invest in high-quality moissanite jewellery, you need to know what to look for.

This buyer’s checklist will help you identify top-grade moissanite so you can make an informed purchase.

✅ 1. Check the Brilliance and Fire

One of moissanite’s most distinctive qualities is its exceptional sparkle. High-quality moissanite has:

• High brilliance – More white light reflection than diamonds.
• Intense fire – A rainbow-like sparkle that’s unique to moissanite.
• Consistent shine – Even sparkle throughout the stone.

💡 Tip: Compare moissanite under different lighting conditions (natural, indoor, LED) to ensure its brilliance is consistent.

✅ 2. Look for Premium Cut Quality

The cut of moissanite plays a crucial role in its overall beauty. A well-cut stone:

• Maximizes brilliance and fire.
• Appears symmetrical and well-proportioned.
• Has precise facets that reflect light evenly.

Best Cuts for Moissanite:

✔ Round Brilliant – Offers the most sparkle.
✔ Oval – Elegant and elongates the finger.
✔ Cushion Cut – Vintage appeal with soft edges.
✔ Princess Cut – A modern square cut with sharp brilliance.

💡 Tip: Avoid shallow or deep cuts, as they reduce the stone’s sparkle.

✅ 3. Choose the Right Moissanite Color

Moissanite comes in different color grades, similar to diamonds.

• Colorless (D-F) – The most premium and purest white.
• Near-Colorless (G-H) – Slight warmth, but still bright.
• Slightly Tinted (I-K) – More noticeable yellow or grey hues.

💡 Tip: If you want a diamond-like appearance, choose D-F color moissanite.

✅ 4. Check for High Clarity

Most moissanite stones have minimal inclusions since they are lab-created. However, clarity still matters.

• Flawless to VVS clarity – No visible inclusions, premium quality.
• VS clarity – Tiny inclusions, not visible to the naked eye.
• SI clarity or lower – Inclusions may affect brilliance.

💡 Tip: Always check the stone under 10x magnification for clarity.

✅ 5. Verify Moissanite Carat Size (or MM Size)

Unlike diamonds, moissanite is measured in millimeters (mm) instead of carats because it is lighter.

💡 Tip: When comparing moissanite to diamonds, focus on mm size, not carat weight.

✅ 6. Look for Certification

High-quality moissanite stones are certified by gemological institutes such as:

• GRA (Gemological Research Association)
• GIA (Gemological Institute of America)
• IGI (International Gemological Institute)

💡 Tip: Always request moissanite certification to verify its authenticity.

✅ 7. Choose a Trusted Seller

Buying from a reputable jeweller ensures you get a genuine, high-quality moissanite stone. Look for:
✔ Positive customer reviews
✔ Transparency about grading
✔ Warranty or return policy

✅ 8. Consider the Setting and Metal Choice

A well-chosen ring setting enhances the brilliance and durability of your moissanite.

Best Metal Choices:

✔ Platinum or White Gold – Enhances a colorless moissanite’s sparkle.
✔ Yellow Gold – Complements slightly warmer moissanite tones.
✔ Rose Gold – Adds a romantic, vintage touch.

💡 Tip: Choose four or six-prong settings for security and elegance.

✅ 9. Test for Authenticity

To confirm you’re getting real moissanite, do the following tests:

✔ Fog Test: Breathe on the stone—moissanite clears quickly, while fake stones stay foggy.
✔ Thermal Conductivity Test: Moissanite conducts heat like a diamond (a jeweler can verify this).
✔ Rainbow Effect Test: High-quality moissanite has a fiery rainbow sparkle, unlike cubic zirconia.

💡 Tip: Buy from trusted retailers with verified authenticity.

Final Thoughts: Choosing the Best Moissanite

High-quality moissanite is a brilliant, durable, and ethical choice for those who want the luxury of fine jewellery without the high price tag. By following this buyer’s checklist, you can confidently invest in a moissanite stone that will shine for a lifetime.
