Most people who sell jewelry online walk away with less than they should have. Not because the jewelry market is broken, but because they never knew what their jewelry was worth in the first place.
The gap between what your jewelry is worth and what you're offered is almost always a knowledge gap.
This guide covers what you should know before engaging in the selling process in the online marketplace, so you can choose the best place to sell your jewelry and feel confident about the outcome.
Unvault offers free AI-powered valuations in about 60 seconds, with no commitment required. Learn more about how Unvault works.
Understand What Your Jewelry Is Worth
Before you photograph anything, fill out a form, or request a quote from anyone. You need a baseline understanding of value.
There is no single number for any piece of jewelry. There are three distinct types of value, and confusing them is how sellers end up feeling shortchanged even when an offer is technically fair.
Melt value
This is what your jewelry is worth as raw metal, based on weight and gold purity. A 14K gold chain weighing 20 grams contains roughly 11 to 12 grams of pure gold.
Gold Melt Value = Weight × Purity × Gold Spot Price
If gold is trading at around $70 per gram, that puts the melt value at approximately $800. That number is your floor, and it's the number cash-for-gold business owners work from.
Fair market value
This is what a willing buyer would pay in an open market with no pressure from either side. For fine jewelry with strong demand, designer branding, or notable gemstones, this can be meaningfully higher than melt value.
This is the number a legitimate resale platform works from.
Retail replacement value
This represents what it would cost to replace the piece at a jewelry store today. This is the number on most insurance appraisals, and it is almost never what you will receive when selling.
It can be two to four times the actual resale value of a piece. If you have an old appraisal document in your jewelry box, use it as a reference for the piece's characteristics, not as a guide for what to expect from any buyer.
Understanding these three numbers before you engage with anyone puts you in a completely different position. You’re able to evaluate whether the offer is fair and a competitive price.
What Else Affects the Value
Gold purity matters enormously. A 24K piece is pure gold. A 10K piece is roughly 42% gold.
The purity is stamped directly on most pieces as a hallmark, often reading 10K, 14K, 18K, or 750 (which means 18K in European notation).
Beyond metal, gemstones, designer brand, and market demand all affect resale value. A plain 14K gold chain and a signed Cartier bracelet in the same weight class will receive very different offers.
Condition matters too. Clasps that work, stones that are secure, and surfaces that are clean all factor into a final valuation.
Know Your Value Before You Sell Anything
Rather than calling a jeweler or pawn shop or mailing your luxury watches to an unknown buyer and hoping for the best, you can now get an instant valuation before committing to anything.
How Unvault Works
Unvault is built specifically for this moment. Upload photos from your phone and receive an AI-powered valuation backed by live precious metals pricing, before you decide whether to sell.
No pressure, no upfront commitment, no guessing. The process takes roughly 60 seconds.
For pieces where you have documentation, original packaging, or receipts, including those alongside your photos strengthens the valuation.
Provenance matters, particularly for designer or estate pieces.

Where to Sell Your Jewelry Online
Not every platform is right for every type of jewelry. Here's how the main options compare.
Evaluation Platforms
Platforms like Unvault show you the price upfront before you ship anything. The selling process is fully transparent:
- Insured shipping is provided
- Authentication is video-documented
- If the final offer doesn't work for you, the piece comes back at no cost
Payouts from transparent resale platforms typically run 70 to 85 percent of gold value, compared to 50 to 60 percent at cash-for-gold shops.
For fine jewelry with designer provenance or strong market demand, the gap can be even larger.
This model removes the information imbalance that makes traditional jewelry sales feel so one-sided. You know what your piece is worth before you commit to anything.
Auction Houses
Auction houses like Sotheby's or Heritage Auctions work well for rare, high-end pieces with real collector appeal. For a signed estate diamond ring or a mid-century brooch with strong provenance, the upside can be meaningful.
For everyday gold jewelry, inherited pieces, or handmade jewelry without a collector following, the timeline and fees rarely justify the process. Auction is a long game, and a slow bidding day can return less than you expected.
Consignment Platforms
Online stores like The RealReal accept fine jewelry on consignment and list it to a broad audience of luxury buyers.¹
Designer names tend to perform well here. Tiffany, Cartier, and Van Cleef move. Generic gold or unsigned pieces often sit unsold, and you may wait months for a jewelry sale to close.
Consignment is worth considering if you have a recognizable designer piece and aren't in a hurry. If neither of those is true, a direct sale is probably the better path.
For designer gold pieces where speed and pricing transparency matter, direct buyers like Unvault can offer a faster alternative to consignment.
Peer-to-Peer Marketplaces
E-commerce platforms like eBay or Etsy give you direct access to potential buyers and the possibility of a better sale price. The tradeoff is that you handle everything yourself: photography, listing copy, pricing decisions, shipping, and any disputes.
For sellers who have the time and experience to manage listings, peer-to-peer can return more per piece. For most people selling personal jewelry, the friction and uncertainty aren't worth it compared to a transparent, managed process.
What to Look for in a Platform
Selling fine jewelry or diamond jewelry online requires trust. A few signals separate reputable platforms from the rest.
Insured Shipping
Non-negotiable. Any legitimate jewelry buyer provides a prepaid, insured label.
If a platform asks you to ship on your own dime, that's a red flag.
Video-Documented Authentication
This builds trust in a way anonymous platforms can't. Knowing that the physical evaluation of your piece is recorded gives you real recourse if any questions arise.
Upfront Valuations
Platforms that show you the offer before you ship put you in control. Platforms that don't are structurally designed to benefit the buyer, not the seller.
A No-Cost Return Policy
The clearest signal of a fair process. If a platform won't return your piece at their expense when you decline an offer, you should question what their incentives are.
How to Get the Best Price
One thing experienced sellers learn quickly: the first offer you see is rarely the only one available.
Know the Spot Price First
Know the current gold spot price before engaging with anyone. It's freely available online and updated in real time.
Running a rough calculation based on karat and approximate weight gives you a floor number to compare against any offer you receive.
Compare at Least Two Platforms
The range of offers across different jewelry buyers can be surprisingly wide for the same piece.
Platforms that show valuations upfront make this comparison easy without shipping your jewelry multiple times.
Gather Your Documentation
Receipts, previous appraisals, and gemstone certificates all strengthen your position. For vintage jewelry or antique jewelry, provenance documentation can meaningfully affect the final offer.
Photograph Carefully
Natural light, a clean neutral background, and multiple angles give platforms the clearest picture of what they're evaluating.
For diamond jewelry or heavily set pieces, close detail shots of the stones are worth including. For any piece with a hallmark, a sharp close-up of the stamp is one of the most useful images you can provide.
When Selling Makes the Most Sense
Not every piece needs to be sold. But there are situations where the financial case is clear and the decision, while emotional, becomes easier once you know the actual numbers.
Inherited Jewelry
Pieces that belonged to a parent or grandparent may carry enormous sentimental weight but go unworn for years. Selling can feel like a betrayal…until you realize what that piece is worth.
Knowing your grandmother's bracelet is worth $2,400 changes the conversation in a way that vague uncertainty never does.
Engagement Rings
After a relationship ends, this is a deeply personal category. The right timing and platform matter, and there's no universal answer. What's worth knowing is that the resale market for diamond jewelry is better than most people expect.
Getting a clear valuation is the first step, regardless of what you decide to do with it.
Unworn Pieces
Jewelry that hasn't been worn in years, that no longer fits your style, or that lives in a drawer rather than on your body is already not serving its original purpose.
Selling it converts a dormant asset into something you can actually use.
Major Life Transitions
Downsizing, estate planning, and divorce often prompt a genuine reassessment of what to carry forward. Vintage jewelry, antique jewelry, and pieces accumulated over decades may include things you love, things you're neutral about, and things that simply no longer belong in your life.
