Verified Trust
Your listing displays the IGI Verified badge - giving buyers independent proof of authenticity before they commit. Fewer questions. More confidence. Faster decisions.
IGI Verified Listing Program
Authenticate with IGI before your listing goes live — buyers see the verified badge upfront, and eligible listings can ship soon after a sale.
Why should you pre-authenticate?
Luxury jewelry pieces carry high value as well as emotional significance. Pre-authentication gives the pieces you plan to sell trusted certification before they go live. Strengthen listing credibility before buyers commit.

Your listing displays the IGI Verified badge - giving buyers independent proof of authenticity before they commit. Fewer questions. More confidence. Faster decisions.
Because your item is already authenticated and held at a GEMGEM hub, it ships the moment it sells - no waiting on the seller to prepare and dispatch. Eligible listings can ship soon after a sale from day one of going live.
The IGI authentication fee is rebated in full from your commission after your item sells, ships via Fast Ship, and the buyer confirms delivery when the review period ends. A successful sale means your net authentication cost is zero.
Two ways to sell
Both options are legitimate paths. Pre-authentication suits sellers who want maximum buyer confidence and faster fulfilment from day one.
The standard path. Your item is listed immediately. Authentication happens after a buyer commits.
Your item is verified with IGI, then kept in secure custody so it is ready to ship fast when it sells. Buyers see the IGI badge and can buy with full confidence.
You pay the IGI authentication fee upfront. After the buyer confirms delivery and the review period ends, the fee is rebated in full from your commission. You pay it temporarily, not permanently.
Standard listings may still require buyer-side authentication after purchase. Pre-authentication is for sellers who want the IGI Verified badge and Fast Ship before going live.
Pre-Authentication Pricing
One upfront IGI pre-authentication fee covers inbound shipping to the hub, IGI authentication, listing preparation, and hub handling. Optional inbound insurance is available at checkout. Rebated in full from your commission after a successful sale.
High-value pieces above $100,000 are managed individually with dedicated concierge handling. Contact our specialist team for a custom authentication process, logistics plan, and quote.
How It Works
Step 3 of 5
IGI gemologists examine and certify your item - typically 3-7 business days after receipt. If IGI confirms a higher value band, you will be asked to pay the tier difference or arrange a return before the process continues.
If It Doesn't Sell
Pre-authentication improves your chances significantly - but here is what to know if your item remains unsold or you choose to withdraw.
Your listing stays live for the full listing period with the IGI Verified badge and Fast Ship label still active.
If you choose to withdraw, you may request your item back from the authentication hub at any time.
Inbound shipping was included in your pre-authentication fee. If you withdraw, return shipping and any return insurance you choose are separate. GEMGEM provides guidance before anything is arranged.
The rebate applies only on a completed sale with confirmed buyer delivery. It does not apply if the item is unsold, withdrawn, or the transaction does not complete.
The pre-authentication fee covers inbound shipping, IGI examination, listing preparation, and hub handling regardless of sale outcome. The rebate is GEMGEM's commitment to sellers whose items find buyers.
