Got old gold jewelry sitting in a drawer? You might be sitting on more money than you think. Whether it’s a broken necklace, a ring from a past relationship, or inherited pieces you’ll never wear, gold holds real value—and pawn shops are one of the quickest ways to turn it into cash. But here’s where most people get tripped up: they walk into a pawn shop with no idea what their gold is actually worth, which makes it nearly impossible to know if they’re getting a fair deal. Understanding how pawn shops evaluate gold puts you in a much stronger position—before you ever walk through the door.
This guide breaks down exactly how gold is valued, from purity and weight to current market prices, so you can sell with confidence.
Gold Purity: The Starting Point for Any Valuation
Not all gold is created equal. The purity of your gold—how much actual gold is in a piece compared to other metals—is the single biggest factor in determining its value.
Gold purity is measured in karats (K). Pure gold is 24K, but pure gold is soft and impractical for everyday jewelry. Most pieces are alloyed with metals like silver, copper, or zinc to improve durability. Here’s how the most common karat values break down:
- 10K gold — 41.7% pure gold. The minimum karat that can legally be sold as gold in the US. It’s more durable and affordable, but carries less gold content.
- 14K gold — 58.3% pure gold. The most common karat in American jewelry. A good balance of durability and gold content.
- 18K gold — 75% pure gold. Often found in higher-end and luxury jewelry. Richer in color and more valuable per gram.
You can usually find the karat stamp on the inside of a ring band, the clasp of a necklace, or the back of a pendant. Look for markings like “10K,” “14K,” “18K,” or their decimal equivalents (417, 585, 750).
If you can’t find a stamp, don’t panic. A pawn shop can test the gold for you—more on that shortly.
Weight and Market Prices: The Math Behind the Offer
Once purity is established, weight is the next piece of the puzzle. Gold is weighed in troy ounces or grams, and even small differences in weight can significantly affect what you’re offered.
Here’s a simplified version of how the calculation works:
- Identify the purity (e.g., 14K = 58.3% gold)
- Weigh the piece (e.g., 10 grams)
- Calculate the gold content (10g × 0.583 = 5.83 grams of pure gold)
- Apply the current spot price — the live market price of gold per gram or troy ounce
Gold prices fluctuate daily based on global markets, so the timing of your sale matters. Checking the current spot price on a site like Kitco or the London Bullion Market Association before your visit gives you a solid benchmark.
Keep in mind that pawn shops don’t pay spot price—they need to account for overhead, resale margin, and risk. Most reputable shops offer somewhere between 50% and 80% of the melt value (the raw value of the gold content). The more knowledgeable you are going in, the better positioned you are to negotiate.
How Pawn Shops Test Gold
A professional pawn shop won’t just take your word for it—they’ll test your gold before making an offer. This is actually a good thing. It protects both parties and ensures you’re being paid for the real value of what you have.
The most common testing methods include:
Acid Testing
A small scratch is made on the piece, and acid of varying strengths is applied. The reaction (or lack thereof) reveals the karat purity. It’s fast, widely used, and reliable for most jewelry.
Electronic Testing
Electronic gold testers use electrical conductivity to estimate purity without scratching the piece. They’re quick and non-invasive, though slightly less precise than acid testing for unusual alloys.
X-Ray Fluorescence (XRF)
XRF machines scan the surface of the gold and provide a detailed breakdown of its metal composition. This is the most accurate and non-destructive method available, and is increasingly common at established pawn shops.
The Magnet Test
This one’s a quick preliminary check—real gold isn’t magnetic. If a piece sticks to a magnet, it’s likely gold-plated or made from a different metal entirely. Reputable shops use this as a first filter, not a final answer.
Free Gold Testing and Appraisals
One thing many people don’t know: you don’t have to pay to find out what your gold is worth. Many pawn shops—including Diamond Jewelry and Loan in Los Angeles—offer free gold testing and appraisals before making an offer. There’s no obligation to sell.
This is worth taking advantage of. Getting a professional assessment not only tells you the accurate value of your pieces, but also gives you a fair baseline if you plan to shop around or sell elsewhere.

Get the Most Out of Your Gold
Walking into a pawn shop informed makes all the difference. Before your visit, take a few minutes to:
- Check your pieces for karat stamps so you know what you’re working with
- Look up the current gold spot price for a real-time benchmark
- Weigh your gold if possible using a kitchen scale (measured in grams)
- Ask about free testing and appraisals—a trustworthy shop will always offer this
Gold doesn’t depreciate the way most assets do. If you’ve got pieces collecting dust, now might be the right time to find out exactly what they’re worth.
