Also consider the Cartier Solitaire 1895 ($9,000–$50,000): classic solitaire. Buy it if you want Cartier engagement.

Also consider the Cartier Love Ring ($2,000–$3,500): screw-motif band. Buy it if you want a Love piece.

Buyer tip

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.

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.
