Selling Gold Jewelry: A Complete Guide to Karat, Value, and What to Expect

Karat is the unit of measurement for gold purity in jewelry. Pure gold is 24 karat, meaning 24 out of 24 parts are gold. Every karat below 24 represents a reduction in gold content and a corresponding increase in alloying metals such as copper, silver, zinc, or nickel. These alloys are added to improve durability, since pure 24-karat gold is too soft for most jewelry applications.

The most common karat marks you will encounter in American jewelry:

The majority of gold jewelry we see in Upstate South Carolina is 10K or 14K. Higher karat jewelry, particularly 22K and above, is common in pieces originating from South Korea, Japan, India, Turkey, and other countries where cultural preference runs toward higher-purity gold. The higher the karat, the closer your payout will be to the current spot price per ounce.

This distinction matters enormously and is one of the most common sources of disappointment at the counter.

Solid gold jewelry is gold all the way through. Traditional rings, necklaces, bracelets, and earrings in 10K, 14K, 18K, or higher are typically solid gold and carry full precious metal value based on their weight and karat.

Gold-filled jewelry has a layer of gold mechanically bonded to a base metal core. The gold layer is thicker than plating but the majority of the weight is still coming from copper, brass, or another non-precious metal. Gold-filled pieces are marked with designations such as GF, 1/10 GF, or 1/20 GF. The fraction represents the gold content as a proportion of total weight, so 1/10 GF means the piece is ten percent gold by weight. These pieces have limited precious metal value.

Gold-plated jewelry has an extremely thin electrochemical deposit of gold over a base metal. The gold content is negligible and adds no meaningful precious metal value. Most costume jewelry is either gold-plated or gold-filled.

Items most commonly found as gold-filled or plated: cuff links, watch cases, lockets, buttons, pins, badge frames, and decorative accessories.

We have an XRF spectrometer on site that can non-destructively identify the exact metal composition of any piece in seconds. If you are uncertain whether your jewelry is solid gold, gold-filled, or plated, we can tell you definitively before any transaction takes place.

This is a section that most gold buyers avoid because the honest answer is not what sellers want to hear. We would rather give you accurate information than a pleasant surprise at the counter.

The diamond market has fundamentally changed. The price of natural diamonds has declined approximately 70 percent since its peak in 2011. The primary cause is the rapid development and adoption of laboratory-grown diamonds, which are chemically, physically, and optically identical to mined diamonds and are now widely available at a fraction of the price of natural stones. The secondary market for natural diamonds has contracted significantly as a result.

Very few diamonds in jewelry are individually valuable. Less than one percent of diamonds used in jewelry are of sufficient quality, size, and cut to be worth removing from the setting and selling as individual stones. The overwhelming majority of diamonds in engagement rings, wedding bands, and fashion jewelry fall below the threshold where a stone buyer would pay a meaningful premium.

The practical implication for sellers: in most cases, you will receive more money for your diamond jewelry by selling the entire piece on its gold weight than by attempting to sell the stone separately. The gold provides the reliable floor value. You would need a large size diamond 1 carat and higher to have a meaningful value placed on the diamond. Smaller stones have value but it's not what most people believe they are. We can remove the diamonds and just purchase the gold and you can find a diamond buyer but at the end of the day, we can most likely satisfy you with a fair offer for both the gold and diamond(s).

We are happy to discuss your specific piece in person and give you our honest assessment of where the value lies.

This is the most important concept in gold selling and the one sellers are most frequently unaware of going in.

Bullion refers to gold in its most tradeable form: coins and bars produced to a fineness of 99.9 percent or higher. Bullion is standardized, easily verified, and traded globally at or very near the spot price. A one-ounce American Gold Eagle or a one-ounce gold bar typically sells at 94 to 99 percent of the current spot price because it requires no further processing to reach the market.

Jewelry is not bullion. Gold jewelry must be refined and processed before it can re-enter the bullion market. That refining process costs money and time, and that cost is reflected in the discount a jewelry buyer applies relative to spot price. A reputable gold buyer working at competitive margins should be paying 85 to 95 percent of the gold value calculated from the piece's weight and karat. Buyers paying less than 80 percent are leaving too much on the table for the seller.

Pawn shops and jewelers are legitimate businesses that serve important community functions. But neither is structured to be a competitive buyer of gold jewelry, and understanding why will help you make a more informed decision about where to sell.

Pawn shops operate a dual business model: retail resale and collateral lending. Their primary profit center is pawn loans, where items are held as collateral against short-term cash loans. When they do buy outright, they are purchasing at steep discounts because their business model is built around customers who need cash immediately and have limited alternatives. Many pawn shops pay less than 50 percent of the calculated gold value on jewelry. Moreover, many pawn shops sell their gold scrap to us.

Jewelers make their margin selling new and estate jewelry to consumers. They are not in the business of buying scrap gold, and when they do, they typically require a substantial discount to justify the administrative cost of handling pieces they cannot resell as-is. Many jewelers we know refer gold sellers directly to us precisely because they do not want the complexity of valuing and purchasing scrap jewelry. Their core business is selling, not buying. And, we purchase gold from many jewelers throughout the Upstate.

A dedicated precious metals dealer has lower acquisition costs, established refinery relationships, and a business model that allows for significantly higher payouts on gold jewelry than either of those alternatives.

The valuation process for gold jewelry is straightforward and takes minutes for most pieces.

Step one: Test the purity. An XRF spectrometer reads the elemental composition of any metal non-destructively in seconds, confirming the exact karat and identifying any plating or unusual alloy content.

Step two: Weigh the piece. The piece is weighed on a precision scale. For items with non-gold components such as stones, clasps, or decorative elements that are not gold, those components are accounted for in the weight calculation.

Step three: Calculate the value. The weight in grams is converted to troy ounces, multiplied by the karat purity factor, and multiplied by the current spot price. The offer is a percentage of that calculated gold value based on current market conditions and the buyer's refining cost structure.

A single gold class ring takes less than 90 seconds to value. A full jewelry box with mixed pieces typically takes 15 to 30 minutes to sort, test, and calculate. Items are separated into solid gold, gold-filled, plated, and non-precious categories before any offer is presented.

Gold jewelry turns up regularly in estate situations alongside coins, silver, currency, and other valuables. If you are working through a loved one's estate and the jewelry box contains a mix of fine jewelry, costume jewelry, class rings, watches, and gold pieces, the most efficient approach is to bring everything in together. We separate the categories, test what needs testing, and make offers on everything at the same appointment.
