If you have old or unwanted jewellery containing stones or gems, maybe inherited pieces, broken items, or simply things you no longer wear – you might wonder: can you sell them? The answer is yes, but there are several legal, practical and financial factors to understand. Here’s what you need to know before selling jewellery with gemstones in the UK.
Why jewellery with gems may have extra value.
Jewellery that includes genuine gemstones (precious or semi-precious) often carries more value than simple metal pieces, because:
- Stone value: Well-cut, high-quality stones (diamonds, rubies, sapphires, emeralds, etc.) can be worth significantly more than the metal or setting alone. Even semi-precious stones (amethyst, aquamarine, garnet etc.) may add value if they are in good condition.
- Design, age, provenance: Antique or vintage jewellery or pieces from reputable makers may command premium prices. Pieces with provenance, strong craftsmanship, or certain styles in demand could sell for more.
- Metal + stones: The value of precious metals in the setting (gold, platinum, silver etc.) plays a part, but stones often are the deciding factor in what someone might pay.
Legal & regulatory things to check.
Selling jewellery is not just about finding a buyer, there are legal and regulatory issues you need to be aware of, especially when gemstones are involved.
Hallmarking of precious metals
If the jewellery piece is made wholly or partly from precious metals (gold, silver, platinum, palladium) above certain weights, then by law it must be properly hallmarked. The hallmark certifies the metal’s purity.
Key points:
- Gold must be over 1 gram to require hallmarking.
- Silver must be over 7.78 grams.
- Platinum 0.5gram, palladium 1 gram, etc.
- It’s illegal to describe something as gold, silver etc., in the course of trade, if it is un-hallmarked and over the weight threshold.
So, when selling something with gemstones, you’ll often also need to think whether the metal part is hallmarked or needs to be. If not, or if you’re selling “as is,” transparency is important.
Disclosures about the gems
Buyers will reasonably expect certain information about the gemstones:
- What kind of stone is it (e.g., natural, lab-grown, treated)? If a gem has undergone treatment e.g. heating, oiling, fracture filling , this should be disclosed.
- Any certification or documentation you might have (e.g. gemological certificate, original purchase papers) helps. Certification adds trust.
- Condition: whether stones are damaged, chipped, loose etc. These materially affect value.
Who buys jewellery with gems?
If you decide to sell, there are several kinds of buyers. The best option often depends on how much your piece is worth, how fast you want to sell, how willing you are to provide documentation, and how “perfect” the piece is.

Buyer / Route
|
Pros
|
Cons
|
|---|---|---|
|
Jewellers / gemstone buyers |
Expert valuers, potential to get fair price for both metal & gem; they understand stones. |
They may offer less than retail replacement value; often keep some margin; they might reject items in poor condition or without documentation. |
|
Online jewellery-buyers / “sell for cash” services |
Convenient; often provide a free valuation or quote; can accept items by post. |
You might get lower offers; risk of shipping damage; postage / insurance costs; if gems are small or damaged, they may be treated as scrap. |
|
Auction Houses |
Good for antique, rare, designer, or especially valuable gemstone jewellery; competition may drive price up. |
Fees and commissions; you may need to wait for the auction; cost of getting the piece ready, possibly cost of certification. |
|
Private sale (online marketplace, local buyers) |
Potentially higher if you find the right buyer; you control price and timing. |
Need to verify authenticity/trust; risk of scams; you need to take good photos, provide documentation; price negotiation; possibly take longer. |
What affects price & how to get a better deal?
Knowing what determines value can help you get more when you sell.
- Gemstone quality
The “4 Cs” – (for diamonds:Cut, Carat, Clarity, Colour) apply. Similar criteria (cut, clarity, colour, carat / size) apply for other gemstones. The better the gem, the more value. Certification helps. - Metal type & weight
If the setting is precious metal (gold, platinum etc.), its weight and purity add to value. Heavy, solid items are worth more than lightweight or plated ones. - Condition
Chips, cracks and loose settings reduce value. Stones need to be secure. If gemstones are missing or damaged, offers will drop. - Provenance and style
Maker’s marks, designer brands, period or antique styles command higher prices. Pieces trending in style may have greater demand. Original packaging or paperwork helps. - Market and demand
The more buyers interested in your type of gem or style, the better. Rare stones or popular gems mean more competition. Also, global market prices for gold, platinum, and gemstones fluctuate. Timing can matter.
Challenges & things to watch out for
Even though you can sell jewellery with gems, it isn’t always straightforward. Some common pitfalls include:
- Low offer vs perceived “value”: Inheritors often see high insurance or retail values, which may not reflect what a buyer will pay in resale. Auction or second-hand market values often are lower.
- Loose stones or missing documentation: Without certificates or with loose settings, buyers will discount heavily.
- Small or low-quality gems: Gems that are tiny, poorly cut, or treated may add negligible value; in some cases, buyers may treat the piece as scrap, focusing only on precious metal.
- Legal compliance and risk: Misstating metal purity, failing to disclose treatments or using unmarked precious metals , can expose sellers to legal risk.
- Shipping & insurance costs: If selling online, especially rare or high-value pieces, you’ll want insurance, secure packaging, and trustworthy courier, those costs need to be factored in.
Steps to sell safely and maximise return.
Here’s a suggested roadmap to follow, to sell unwanted gemstone jewellery smartly:
- Get an appraisal
If possible, have a reputable jeweller or gemologist assess the gemstone(s), document weight, cut, clarity, treatment status. Even a rough estimate helps. - Find documentation
Receipts, certificates, maker’s marks, photos of condition will all help. If you don’t have them, any hallmarks on the metal parts are useful. - Decide your route
Choose whether to use jewellers, online buyers, auction houses, or private sale depending on value & urgency. - Prepare the item
Clean it sympathetically if required/possible and ensure settings are secure. Use quality photos if selling online. - Disclose honestly
Be clear about any damage, treatments, documentation etc. Full honesty builds trust and protects you. - Compare offers
Get multiple valuations/quotes. Offers can vary widely depending on buyer’s expertise, overheads, demand. - Check credentials of buyer
If using an online buyer, check reviews, business credentials, whether they are members of trade bodies (British Jewellers’ Association, etc.). Auction houses or jewellers with good reputation are safer. - Understand costs and fees
Auction fees, commission, shipping, insurance, any restoration costs should be factored in.
Summary: Yes, but do your homework
In short, you can sell old or unwanted jewellery that contains stones or gems. But how much you get, how easy it is, and how much hassle is involved depend on:
- The quality, type, size, condition of the stones
- The metal type and whether it’s hallmarked.
- The documentation or provenance you can provide.
- The buyer you choose.
- Legal obligations (hallmarking, honest disclosure etc.)
If you’re prepared, you’ll be able to convert jewellery items you no longer want into cash or trade-in, or reuse without unpleasant surprises.
