Fine jewelry rings

What decides it

Size: get sized at a jeweler, in the afternoon, at normal temperature; many rings cannot be resized. Profile: low-set stones and smooth bands suit daily wear and do not snag. Metal: platinum is durable for diamond settings; 18k gold is softer and shows scratches.

The pieces we would buy

Start with the Cartier Trinity Ring: three interlaced bands. The Tiffany & Co. Setting Engagement Ring is the better buy if you want the classic engagement ring. Usual prices run from $1,000 to $100,000. See the full buy-or-skip list or the head-to-head Cartier Trinity Ring vs Tiffany & Co. Setting Engagement Ring.

Buying in the US and Europe

Check if a ring can be resized before buying: eternity and some sculpted rings cannot be resized at all. Buying in Europe: gold jewelry in the EU and UK is often hallmarked (750 for 18k gold). Ask for the hallmark and, for any diamond over about 0.3 carats, a grading report from GIA, HRD or IGI.

Quick answers

Can designer rings be resized? Plain bands usually can, by the brand. Eternity rings and many sculpted designs cannot. Is a Cartier Trinity worth it? It is a timeless three-gold design that suits men and women. You pay a design premium over plain gold bands.

Luxury prices move in a different rhythm from everyday shopping. The great houses (Chanel, Hermès, Louis Vuitton, Dior, Rolex) raise prices once or twice a year, often in January and in spring, and almost never discount their icons. Seasonal pieces, colors and many shoes, coats and knitwear drop 30–50% in the end-of-season sales in January and from late June. Watches from brands such as Omega, TAG Heuer, Longines and Breitling, and most fragrance, see the best prices around Prime Day and Black Friday. Judge any deal against the usual price we show.

Buy from the fashion house, an authorized retailer or a reseller that authenticates and guarantees every piece, and keep the receipt, the dust bag, the box and any warranty card: they matter for repairs and for resale. Swiss watches carry a 2- to 5-year international warranty when bought from an authorized dealer, and buyers in the EU and UK also have a legal guarantee of at least two years on new goods.

How we make the call: we read the house’s own product details and care guides, compare materials and construction, follow owners’ long-term experience and track the usual retail and resale prices. A piece gets “Buy” only if we would tell a friend to spend that money on it. No fashion house can pay for a verdict.
