The trade-offs

Good: superb. Not so good: pricey. Read the skip-if line before you spend: skip it if you want small.

What to buy instead

Instead, consider the Van Cleef & Arpels Vintage Alhambra Earrings ($5,000–$7,000): clover earrings. Better if you want VCA.

Instead, consider the Van Cleef & Arpels Perlée Hoops ($4,000–$6,000): perlée hoops. Better if you want delicate.

Instead, consider the Bulgari Serpenti Earrings ($4,000–$8,000): serpenti earrings. Better if you want Bulgari.

Before you buy

Backs: screw backs or secure push backs reduce the risk of losing a stud. Weight: big drops and hoops in solid gold can be heavy; check weight for all-day wear. Metal: 18k gold and platinum are hypoallergenic for most people; avoid mixed alloys if sensitive.

Buyer tip

Diamond studs are where certificates matter most: compare carat, color and clarity across houses, not only the brand.

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.

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.
