8 Tips to Increase Your Gold & Diamond Resale Value
Last time on the blog we talked about what influences the resale value of gold and diamonds. Now that you know what goes into that value, let’s take a look at how you can increase your value! While the market value of gold and diamonds plays a role, there are several ways you can maximize your resale value before selling. From proper maintenance to choosing the right buyer, small steps can lead to a significant difference in your final payout. At Stewart Kuper Jewelers, we want you to get the best value for your jewelry. Here’s how you can make sure you walk away with top dollar.
8 Tips to Increase Your Gold & Diamond Resale Value
1. Keep Your Jewelry in Good Condition
While gold itself doesn’t lose value due to scratches or tarnish, the condition of your jewelry can impact how much buyers are willing to pay. A well-maintained piece may sell for more than one that looks worn out, especially if the buyer plans to resell it as-is rather than melt it down.
For diamonds, chips, cracks, and cloudy stones can reduce their value. Keeping them clean and storing them properly helps maintain their appeal.
- Clean your jewelry regularly using a soft cloth and mild soap.
- Avoid harsh chemicals that can damage gemstones and metals.
- Store your pieces separately to prevent scratches, especially for diamond jewelry.
If your jewelry needs professional cleaning or minor repairs, doing this before selling can sometimes increase its resale value.
2. Know the Purity and Weight of Your Gold
Buyers determine the value of gold jewelry based on its karat purity and weight. Higher-karat gold contains more pure gold and is worth more. For example, an 18K ring will fetch a higher price than a 10K one of the same weight because it contains more gold.
You can check the karat marking on your jewelry (e.g., 10K, 14K, 18K) or have it tested by a jeweler.
At Stewart Kuper Jewelers, we provide free evaluations to determine the precise purity and weight of your gold.
3. Get a Certification for Your Diamonds
If you’re selling a diamond, having a certification from a reputable gemological lab—such as GIA (Gemological Institute of America) or AGS (American Gem Society)—can increase its value. Certified diamonds typically sell for more because buyers trust their quality and authenticity.
If your diamond isn’t certified, consider getting it evaluated before selling. While it’s an extra step, it can help prove its worth and ensure you get a fair price.
4. Sell When Market Prices Are High
Gold and diamond prices fluctuate based on supply, demand, and economic conditions. Selling during a time when gold prices are high can significantly increase your payout.
To check current gold prices, you can look up the spot price of gold online or visit a trusted jeweler like Stewart Kuper Jewelers for an up-to-date market evaluation.
Diamond prices are influenced by trends and demand. Popular diamond shapes and sizes tend to sell for more, so it’s worth checking the market before selling.
5. Sell to a Trusted Buyer
Where you sell your jewelry matters just as much as what you’re selling. Different buyers offer different prices, and not all of them are transparent or fair.
Avoid:
- Pawn shops – typically offer low prices since they resell at a markup.
- Mail-in gold buyers – May have hidden fees and low payouts.
Choose:
- Reputable jewelers and gold buyers – These offer competitive prices and honest evaluations.
At Stewart Kuper Jewelers, we provide fair, transparent, and competitive offers with no pressure to sell. We base our prices on real-time market rates and offer instant payment.
6. Sell Whole Pieces Instead of Scrap
Gold buyers often melt jewelry down for its gold content, but some pieces may be worth more intact. If you have designer or antique jewelry, it may have added value beyond just the gold weight.
For example, a branded ring from Tiffany & Co. or Cartier could sell for more than its melt value because of its prestige and craftsmanship. Before selling, check if your jewelry has brand markings or unique designs that could increase its worth.
At Stewart Kuper Jewelers, we assess your jewelry holistically and offer higher prices for valuable designer pieces.
7. Keep Your Documentation
Original receipts, diamond certificates, and appraisals can boost the resale value of your jewelry. These documents verify authenticity and quality.
If you have any paperwork related to your jewelry, bring it along when selling. If not, we can help you get an updated appraisal at Stewart Kuper Jewelers.
8. Compare Offers
Never accept the first offer without comparing. Different buyers may offer different prices, and shopping around ensures you get the best deal.
At Stewart Kuper Jewelers, we encourage customers to compare offers because we’re confident in our competitive pricing. We’ll even match or beat offers from reputable buyers in many cases.
