Finding the Right band-rings for You

If you’re shopping for antique and vintage band rings, you likely know that this particular kind of ring is among the most versatile in jewelry.

You don’t need a special occasion to dazzle friends with a flashy sapphire band ring or to make a statement with a wide band ring — this accessory knows no boundaries, and many different iterations have materialized over the years. Whether you’re seeking an unadorned modern sterling-silver band ring for everyday wear or dual gold wedding bands for the big day, there are lots of options waiting for you.

On 1stDibs, there are enduring antique wedding bands to be found dating from the Victorian and Edwardian eras. Jewelers who were active during the reign of Queen Victoria — specifically, the Romantic period — designed rings with large colorful gemstones and decorative motifs, while the jewelry of the latter era was all about the exquisite diamond, platinum and pearl creations made by such famous names as Cartier and Boucheron. Matching wedding bands, which may reduce the stress of wedding-band shopping if you prefer a traditional route, afford you and your partner the chance to have the engagement ring and wedding bands in the same metal and design.

And because band rings aren’t necessarily relegated to black-tie events, they’ve come a long way, design-wise. David Yurman’s band rings, for example, are well known for their integration of mixed metals, and the celebrated jewelry designer’s powerful silver and gold bracelets, rings, pendants and earrings frequently express his iconic industrial-cable motif.

A simple and chic band ring goes with anything, from the evening gown you’ve chosen for a weekend gala to the jeans and vintage tee you’ve thrown on for a casual lunch with colleagues. Browse a distinctive collection of contemporary and vintage diamond band rings, gold band rings and other accessories on 1stDibs today.
