How much is a gold chain worth? The honest answer is: it depends on three things, and none of them is fixed. Your chain’s value comes down to its weight, its purity, and the price of gold on the day you walk in the door. That’s the real question most people are asking when they dig an old necklace out of a drawer: what will a buyer actually pay me for this?
This guide covers both halves of that question. First, how to work out a realistic dollar figure for your chain or necklace before you ever speak to a buyer. Second, how to find a buyer who pays you fairly for it, rather than one who counts on you not knowing the difference. One thing worth setting straight from the start: the number you get offered will always be lower than what the piece would cost new in a store. That is normal, and on its own it does not mean anyone is trying to cheat you.
What Actually Determines Your Gold's Value
Three levers decide the number: how much your piece weighs, how pure it is, and what gold is trading for that day. Move any one of them and the value changes with it.
Weight: Buyers typically weigh jewellery in grams, though you may also see pennyweight used, especially in older price sheets (one pennyweight equals about 1.55 grams). A heavier chain is not automatically worth proportionally more if its purity is lower, so weight only tells part of the story on its own.
Purity, or karat: Pure gold is 24 karat, but it is too soft for everyday jewellery, so most chains are alloyed with other metals. The karat stamp tells you what fraction of the piece is actual gold. A 10k chain contains less pure gold, gram for gram, than an 18k or 22k chain, so purity has a direct and significant effect on final value.
The current spot price: Gold trades on a global market, and its price per gram moves throughout the day. Whatever figure you calculate is only accurate for that moment, which is why checking a live price source matters more than relying on a number from last week or from memory.
| Karat | Purity (Gold Content) | Typical Use |
|---|---|---|
| 10K | ~41.7% | Everyday wear, kids' jewellery, budget pieces |
| 14K | ~58.3% | Most common chain and necklace karat in North America |
| 18K | ~75.0% | Higher-end jewellery, better durability-to-purity balance |
| 22K | ~91.7% | Traditional and cultural jewellery, softer metal |
| 24K | ~99.9%+ | Pure gold, rarely used in everyday chains |
How to Calculate What Your Gold Chain Is Worth
Once you know the weight and karat, the formula is simple: weight in grams, multiplied by the purity factor for that karat, multiplied by the spot price per gram, gives you the melt value.
Worked example 1 — a 14k gold chain: Say your chain weighs 15 grams. Fourteen-karat gold is about 58.3 percent pure. If the spot price that day happened to be a certain amount per gram, you would multiply 15 by 0.583, then by that day’s spot price, to land on the chain’s melt value. This is only an example figure. Always check the live spot price before doing your own math, since it changes daily and sometimes hour to hour.
Worked example 2 — a gold necklace: The same formula applies to a necklace’s value. A 20-gram, 18k necklace would be calculated as 20 multiplied by 0.75, multiplied by that day’s spot price per gram. The math does not change based on whether the piece is called a chain or a necklace; only the weight and karat differ from item to item.
Keep in mind that this melt value figure is not what a buyer will hand you in cash. It is the starting point for the offer, and a rough online cash-for-gold calculator will only ever get you an estimate in this same range. What comes next explains why the final offer sits below this number.
Why You Get Less Than Melt Value When You Sell
This is the part that catches people off guard, and it is also where a lot of unfair suspicion gets aimed at buyers who are actually being reasonable. Understanding the gap helps you tell a fair scrap gold chain price from a genuinely bad one.
Scrap gold pricing and refining costs: Once your chain is sold, it is typically melted down and refined back into pure gold before it can be resold or reused. Refining costs money and takes time, and the buyer also carries the risk of gold prices shifting before the metal is processed and moved on. That built-in cost and risk is baked into the scrap gold chain price you are offered, and it is standard across the industry, not a sign of a particular buyer trying to shortchange you.
What a fair payout looks like: As a rough guideline, a fair offer commonly lands somewhere in the range of 70 to 90 percent of true melt value, though this varies by buyer, by karat, and by local competition. An offer noticeably below that range, especially if it comes with pressure to accept quickly, is worth questioning. An offer at the high end, or one that comes with a clear written breakdown of weight, karat, and rate per gram, is a good sign you are dealing with someone straightforward.
How to Identify a Legitimate, Reputable Gold Buyer
This is the step most guides skip entirely, and it matters just as much as knowing the number. A correct valuation means nothing if you hand your gold to the wrong buyer.
Signs of a trustworthy buyer: A legitimate buyer weighs your piece in front of you, on a visible, calibrated scale, and explains the karat testing method they are using before touching your jewellery. They will tell you the current spot price they are working from and show you their math, rather than simply naming a final number. Look for a buyer who is properly registered as a business, who gives you a written offer or receipt before any cash changes hands, and who is comfortable with you taking time to think it over or get a second opinion elsewhere.
How to check a buyer’s reputation: Before you commit, look up independent customer reviews rather than only testimonials on the buyer’s own website, and pay attention to how they respond to negative reviews, not just the star rating. Confirm the business is properly registered and has a real, verifiable physical presence, and check whether they are affiliated with any recognized industry or trade associations. A quick search for the buyer’s name alongside words like “complaint” or “review” often surfaces useful red flags fast.
Red Flags and Common Gold-Selling Scams
Most gold-selling problems fall into a few repeating patterns. Learn to spot these and you avoid the vast majority of bad experiences.
Pressure tactics and “today only” offers: Any buyer who tells you the price is only good for the next ten minutes, or pushes you to decide before you have had a chance to think, is using urgency to stop you from comparing offers. A genuine buyer will not lose interest in your gold overnight.
Weighing and purity tricks: Watch for scales that are not visible to you, magnets hidden near the scale, or acid testing done out of view. Some less scrupulous buyers will also round karat down or claim a piece is lower purity than its hallmark states, without clearly explaining why.
No paperwork or written offer: If a buyer refuses to put the weight, karat, rate per gram, and total offer in writing before you agree to anything, treat that as a serious warning sign. Legitimate transactions leave a paper trail.
How to Compare Offers and Get a Fair Price
Getting a fair price is less about finding one perfect buyer and more about giving yourself the information to compare properly, including knowing how local jewellers and online gold buyers tend to pay differently.
Get at least three quotes, and try to get them on the same day, since the spot price moves daily and comparing a Monday quote to a Thursday quote is not a fair test. Ask each buyer for their per-gram rate broken down by karat, in writing, so you can compare like for like rather than a single vague total. Remember that you are always allowed to decline an offer and walk away. A buyer who reacts badly to that, or tries to talk you out of leaving, is telling you something important about how they operate. If one offer comes in noticeably below the others, that is usually the outlier worth being suspicious of, not the norm you should expect.
Before You Sell: Quick Checklist
- Confirm the weight and karat of your piece independently, ideally before you visit a buyer
- Check that morning’s spot price so you have a rough value in mind
- Separate pieces by karat, and remove clasps, stones, or other non-gold parts if you can
- Get multiple written quotes before accepting any single offer
- Verify the buyer’s reputation and business registration before handing anything over
FAQ
How much is a gold chain worth when you sell it?
It depends on the chain’s weight in grams, its karat or purity, and the current gold spot price on the day you sell. Multiply those three figures together to get the melt value, then expect a buyer to offer a percentage of that number, not the full melt value or the original retail price.
How can I find out how much my gold chain is worth at home?
Weigh it on a gram scale, check the karat stamp usually found near the clasp, and look up the current spot price online. Multiply weight by the purity percentage for that karat, then by the spot price per gram. Online cash-for-gold calculators can also give a quick estimate, but treat the result as a starting point rather than a guaranteed offer.
How do I know if a gold buyer is legitimate and trustworthy?
Look for a buyer who weighs your piece in front of you, explains their testing method, and shows you the spot price they are using. Check independent reviews, confirm they are a properly registered business, and make sure they are willing to give you a written offer before you agree to sell.
What percentage of the gold's value should a fair buyer pay?
There is no single fixed number, but offers in roughly the 70 to 90 percent range of true melt value are generally considered reasonable, depending on karat and local market conditions. Refining costs and market risk are the main reasons the payout sits below full melt value.
