Fine jewelry necklaces

What decides it

Chain length: 40–45 cm sits at the collarbone; layering needs 5 cm steps. Clasp: a lobster clasp is more secure than a spring ring for daily wear. Diamonds: ask for the grading report (GIA or similar) for any stone over about 0.3 carats.

The pieces we would buy

Start with the Van Cleef & Arpels Vintage Alhambra Pendant: single clover pendant. The Mikimoto Akoya Pearl Strand is the better buy if you want a lifetime pearl necklace. Usual prices run from $350 to $200,000. See the full buy-or-skip list or the head-to-head Van Cleef & Arpels Vintage Alhambra Pendant vs Tiffany & Co. Elsa Peretti Diamonds by the Yard.

Buying in the US and Europe

A small motif pendant in 18k gold is the most worn piece of fine jewelry; buy that before a statement necklace. 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

Which necklace length is most versatile? About 42 cm, which sits on the collarbone with almost any neckline. Are lab-grown diamonds fine jewelry? They are real diamonds grown in a lab and cost far less, but they do not hold resale value.

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.
