20 Questions to Ask Before Buying Moissanite Online (That Most Buyers Never Think to Ask)

August 27, 2026

Most moissanite buyers do some research before purchasing — they read a few comparison articles, look at some photos, and check the price. But very few buyers ask the specific, targeted questions that separate a great moissanite purchase from a disappointing one. The difference between a ring you'll love for a lifetime and a ring you'll regret often comes down to questions you didn't know to ask.

This guide gives you the 20 most important questions to ask any moissanite seller before you spend a dollar. Some of these questions will be answered on the seller's website. Others you'll need to ask directly. All of them matter.

Questions About the Stone's Quality

1. What is the exact color grade of the stone?

Don't accept vague descriptions like "colorless" or "near-colorless." Ask for the specific GRA color grade: D, E, F (colorless) or G, H (near-colorless). DEF is the highest quality tier. GH stones may show a slight tint in certain lighting conditions. Every Moissanite Shine stone is DEF color.

2. What is the exact clarity grade?

Ask for the specific GRA clarity grade: VVS1, VVS2, VS1, or VS2. VVS1 is the highest clarity grade available in moissanite. Every Moissanite Shine stone is VVS1 clarity. For a complete explanation of clarity grades, see: Moissanite Clarity Grades Explained.

3. What is the cut grade, and what are the specific cut proportions?

Ask for the cut grade (Excellent, Very Good, Good) AND the specific proportions: table percentage, depth percentage, and crown angle. Two stones with the same Excellent cut grade can look dramatically different depending on their specific proportions. For a complete explanation, see: Why Two Same-Grade Moissanite Stones Look Different.

4. Does the stone come with a GRA certificate?

A GRA certificate is the industry standard for independent quality verification. Without it, you're taking the seller's word for the stone's quality. Ask for the certificate number so you can verify it in the GRA's online database. For a complete guide to reading a GRA certificate, see: How to Read a GRA Certificate: A Step-by-Step Visual Guide.

5. Is the certificate number verifiable online?

A genuine GRA certificate has a certificate number that can be verified on the GRA's official website. Ask the seller to confirm that the certificate number is verifiable, and verify it yourself after receiving the ring.

6. What is the stone's carat weight — actual weight or diamond equivalent weight (DEW)?

Moissanite is lighter than diamond. A stone described as "1 carat" may mean 1 carat actual weight or 1 carat diamond equivalent weight (DEW). The GRA certificate will show the actual carat weight. A 1 carat DEW moissanite has an actual weight of approximately 0.88 carats.

Questions About the Setting and Metal

7. What is the metal purity of the setting?

Ask for the specific metal purity: 14K gold (58.3% pure gold), 18K gold (75% pure gold), or platinum (95% pure platinum). Avoid sellers who describe their metal as "gold-plated" or "gold-filled" without specifying the base metal — these are not fine jewelry metals.

8. Is the setting rhodium-plated, and if so, how often will it need re-plating?

White gold settings are typically rhodium-plated to achieve their white color. Rhodium plating wears off over time and needs to be renewed every one to three years. Ask the seller whether the setting is rhodium-plated and what the re-plating process involves.

9. Can the ring be resized, and if so, by how many sizes?

Not all ring styles can be resized. Eternity bands and rings with stones all the way around the band typically cannot be resized. Ask the seller whether the specific ring you're considering can be resized, and by how many sizes in each direction.

10. Is the stone set securely, and what type of setting is used?

Ask about the setting type (prong, bezel, flush, pavé) and whether the stone is set securely. Prong settings require periodic inspection to ensure the prongs haven't loosened. Bezel settings are more secure but show less of the stone. For a complete guide to setting types, see: Moissanite Ring Settings Explained.

Questions About the Seller's Policies

11. What is the return window, and what are the conditions?

A reputable moissanite seller should offer a minimum 30-day return window. Ask about the conditions: Does the ring need to be unworn? Are there restocking fees? Who pays for return shipping? A seller with a short return window or restrictive conditions is a red flag.

12. Is resizing included, and for how long after purchase?

Many reputable sellers offer free resizing within a specified period after purchase. Ask whether resizing is included, how long the free resizing window lasts, and whether there are any conditions. We offer free resizing within 30 days of purchase.

13. What does the warranty cover, and for how long?

Ask for the specific terms of the warranty: What is covered? What is excluded? How long does it last? A genuine lifetime warranty covers the stone forever — not for 90 days, not for a year. Our Lifetime Gemstone Warranty covers your stone forever. For a complete explanation, see: The Lifetime Warranty Explained.

14. Is there an upgrade program, and what are the terms?

Some moissanite sellers offer upgrade programs that allow you to trade in your current stone for a larger or higher-quality stone in the future. Ask whether an upgrade program is available and what the terms are. Our Lifetime Upgrade Program allows you to upgrade your stone or metal at any time.

15. How is the ring shipped, and is it insured?

Fine jewelry should be shipped with full insurance and signature-required delivery. Ask the seller how the ring is shipped, whether it's insured, and what happens if the package is lost or damaged in transit. We ship all orders fully insured with signature-required delivery.

Questions About the Seller's Credibility

16. How long has the seller been in business?

A seller with a long track record is more likely to be reliable than a new seller with no history. Ask how long the seller has been in business and look for verifiable evidence of their history — customer reviews, social media presence, and business registration information.

17. Are the customer reviews verified and independent?

Ask where the seller's customer reviews are hosted and whether they're verified. Reviews on the seller's own website are less reliable than reviews on independent platforms. Look for reviews on Google, Trustpilot, or other independent review platforms.

18. Can I see photos of the actual ring I'll receive, not just stock photos?

Many online jewelry sellers use stock photos that may not accurately represent the actual ring you'll receive. Ask whether you can see photos of the actual ring — or at minimum, photos of rings made with the same stone and setting that you're ordering.

19. What is the seller's process for handling defects or quality issues?

Ask the seller what happens if the ring arrives with a defect — a loose stone, a scratched setting, or a quality issue. A reputable seller will have a clear, customer-friendly process for resolving these issues. A seller who is vague or evasive about this question is a red flag.

20. Is the seller's contact information complete and verifiable?

A reputable seller should have a complete, verifiable contact information: a physical address, a phone number, and an email address. A seller who can only be reached through a contact form or social media DM is a red flag. Verify that the contact information is real before purchasing.
