How to sell a diamond engagement ring.

You have five options. From highest typical payout to lowest:

1. Private resale via auction-style services. Worthy.com and IDoNowIDont auction your stone to a network of vetted buyers. Net 35-50% of retail after their commission (15-18%). Timeline 4-8 weeks. Best for stones over 1.5ct with GIA certs. They take a strong photo, write a description, and let buyers bid.

2. Private resale via classifieds. eBay, Facebook Marketplace, IDoNowIDont marketplace. Net 35-55% of retail. Timeline weeks to months. Buyer-protection drama is the failure mode. Most rings under 1ct don't sell here — too much competition from new lab-grown.

3. Diamond District jeweler (47th street NYC, downtown LA, etc.). 25-35% of retail. Same-day cash. Bring at least three jewelers your stone before accepting. Diamond-district jewelers know each other and price-match honest competing offers. Don't try this with mall jewelers or chain stores — they're a different market.

4. Local independent jeweler. 20-35% of retail. Same-day to 1 week. Quality varies wildly — a respected family-run jeweler may pay close to a Diamond District buyer; a strip-mall chain pays much less.

5. Pawn shop. 10-25% of retail. Same-day cash. Faster than jewelers, lower offers. Best when speed matters more than maximum price.

What to bring: the GIA/IGI certificate (most valuable thing in the conversation), original purchase receipt if you have it (sometimes increases offer), the ring's setting metal type (gold karat, platinum), and a clean stone (drop it in soapy water for 10 minutes; do NOT polish it).

What to skip: appraisals from random "diamond appraisal" shops in malls — these are not real grading, the appraiser usually has a financial relationship with a buyer, and the "appraised value" is not a price you'll get.
