DIAMOND RETAILER REVIEWS
The best retailer is the one that fits your purchase.
A retailer can have a huge inventory and still be the wrong fit for your decision. Compare the shopping tools, evidence, policies, service, and total purchase before choosing where to buy.
Your consultation is free. Retailers can pay us a commission on qualifying referrals at no extra cost to you. Read how referrals work.
START WITH THE PURCHASE
What matters most to you?
✓Seeing the actual diamond clearly
✓Cut and light performance evidence
✓Selection at a specific budget
✓Return, upgrade, and shipping terms
✓Help comparing two finalists
A score is the start of the comparison.
Read the category scores and the written evidence behind them. A strong customer service score does not answer whether the listing shows the diamond clearly. A large inventory does not guarantee that the right stone is easy to find.

Retailer details, prices, policies, inventory, and tools can change. Confirm the current terms on the retailer's site before buying.
RETAILER SCORE VERSUS DIAMOND REVIEW
A high retailer score does not approve every diamond on the site.
The score evaluates the shopping experience, selection, tools, service, price, and policies. The actual diamond still needs its own review.
A TRADE DETAIL WORTH KNOWING
The same diamond can appear on more than one site.
Match the grading report number and measurements before treating two listings as two different stones. When they match, compare the current total price, return terms, shipping, and service.
Six categories. No mystery total.
01
First impressions

Which tools, guarantees, upgrade terms, or services improve the actual buying decision?
BEFORE YOU PAY
Check the terms that protect the decision.
✓The return window starts and ends on clear dates.
✓Any restocking, resizing, or setting exclusions are in writing.
✓Shipping is insured in both directions when a return is needed.
✓The report number and listing details match the stone.
✓Upgrade, warranty, and buyback language means what you think it means.
Comparing two listings?
Send both links, both asking prices, and the question you want answered. If the report numbers match, say so.
Compare two diamonds↗SEPARATE THE SELLER FROM THE STONE
A good retailer can still list a diamond you should skip.
Retailer quality and diamond quality are separate decisions. Use the seller review to understand the buying environment. Use the grading report and visual evidence to evaluate the actual diamond.
Keep the referral relationship visible
Some retailer links can earn Your Diamond Guys a commission on a qualifying purchase. The review should still tell you what the available evidence supports and what it does not.
