Cartier’s Trinity Ring Ranks as the Best Jewelry Investment Piece in 2026
According to a January 2026 report on the high-end jewelry market, Cartier’s Trinity Ring has grown more in value than any other classic piece over the past 5 years. The study by FashioNica, a vintage handbag shop, analyzed iconic jewelry pieces from heritage brands to identify which have increased in price the most since 2020.
The research documented and analyzed classic pieces from brands like Cartier, Bulgari, Chanel, Van Cleef & Arpels, Hermès, and Tiffany & Co. Researchers then looked at how much prices have grown by comparing what each piece costs today against its price five years ago. The study also measured consumer interest by tracking how often people search for these pieces online and how well they hold their value after purchase.
1. Cartier Trinity Ring
Cartier’s Trinity Ring has seen the biggest retail price surge among all the heritage pieces. Five years ago, this three-band design cost $1,420, and today it sells for $2,350, a 65% jump that beats everything else in the ranking. More than 200K people search for this ring online each year, and when owners resell it, they get about $2,000, which is 85% of what they originally paid.
2. Bulgari B.Zero1 Ring
Bulgari’s B.Zero1 Ring comes second with a 41% price increase from $2,700 to $3,800. The ring’s bold design appeals to many buyers, with more than 67K people looking it up online every year. B.Zero1 also holds its value quite well, even if you decide to resell it. They typically go for $2,800 on the second-hand market, meaning you can get about 75% of what you paid.
3. Chanel Coco Crush Bracelet
Chanel’s Coco Crush Bracelet is also among the best jewelry investments. Over the past five years, its price has climbed 36%, going from $11.5K to $15.7K. Fewer people search for this piece compared to others. Despite the lower consumer interest, it still holds strong resale value at $10K, about 63% of the current store price.
4. Chanel Coco Crush Ring
The Coco Crush Ring climbed 33% from $2,450 to $3,250 over the past five years. Many people want this piece, with 35K checking it in online shops every year. It also keeps its worth well after purchase: owners who sell theirs usually get around $2,500 back, about 77% of what they originally spent. Plus, this ring costs less than most pieces here, making it an easier way to own Chanel fine jewelry.
5. Van Cleef & Arpels Alhambra Necklace
Van Cleef & Arpels’ Alhambra Necklace rounds out the top five with a 33% price increase from $4,300 to $5,700. This necklace is one of the most sought-after pieces, with 2.6 million people looking it up online each year, far more than any other design studied. With that level of interest, its second-hand market price now sits at $4,800, keeping 84% of what you’d pay at the store.
A jewelry market analyst commented on the study: “The Trinity Ring contains about 7 grams of 18k gold, worth roughly $750 in raw materials at today’s prices. But the piece retails for $2,350, meaning the Cartier name adds about $1,600 in brand value; more than double what the metal itself costs. And that $1,600 difference represents the value of owning a piece that’s been iconic since 1924.”
