Many people own jewelry pieces that have been tucked away over the years—gifts from loved ones, inherited family heirlooms, or items that simply no longer suit their style. While some of these may be sentimental keepsakes, others have the potential to hold significant market value. If you’re considering selling or just want to better understand what you own, learning how to identify a valuable piece is a smart place to start.
Here’s what to look for when evaluating the potential worth of your jewelry collection!
Check for Hallmarks
Start by looking for small, stamped markings, usually on the inside of a ring or clasp. These hallmarks can reveal important information like metal purity (such as 14K or 18K for gold, 925 for sterling silver, or PLAT for platinum) or the maker’s mark. A well-known designer stamp from brands like Cartier, Tiffany & Co., or Van Cleef & Arpels can instantly increase a piece’s value.
It doesn’t necessarily mean the piece isn’t valuable if you don’t see a stamp. It may just need a professional evaluation to confirm what you have.
Look Closely at the Stones
Real diamonds and gemstones have specific traits that make them stand out. Diamonds, for example, reflect both white light (brilliance) and rainbow-colored flashes (fire). You can use a loupe or magnifying glass to check for clarity and overall quality.
High-value gemstones like sapphires, rubies, and emeralds may show signs of age or hand-cutting, which can add vintage appeal. Unusual gemstone cuts or one-of-a-kind settings may also suggest the piece comes from a particular design period, adding to its value.
Notice the Craftsmanship
Fine jewelry, especially vintage or estate pieces, often includes craftsmanship that’s hard to find in today’s mass-produced market. Look for hand-engraved details, milgrain edging, or delicate filigree work. These features are common in pieces from the Edwardian, Art Deco, or Retro periods, and they are typically valued by collectors and buyers alike.
Consider Its History
Was the piece passed down through generations? Purchased many years ago during a significant event? Jewelry with a story or historical context can sometimes hold more value, especially if it’s connected to a well-known design era or carries sentimental significance that translates to buyer interest.
Don’t Let Value Sit in a Drawer
You don’t need to be a jewelry expert to uncover a hidden gem in your collection, but having a professional evaluation can make all the difference. A quick look by the right set of eyes could reveal that a long-ignored item is more valuable than you ever imagined.
