The checklist

  • 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.

Set your budget

The fine jewelry necklaces we researched sell for $350 to $200,000 in the US. Decide how often you will wear it first; the most expensive piece is often a skip for everyday life.

Buyer tip

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

Buying in Europe

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.

Before you buy a fine jewelry necklace: the essentials

Buying a fine jewelry necklace is easier once you know which details actually change how it looks and lasts, and which are just marketing. This guide covers exactly that, plus the budget to plan for, sizing and buying across the US and Europe, and the pieces we would buy today.

The checklist

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.

What to spend

The fine jewelry necklaces we checked sell for $350 to $200,000. Below that range you usually lose materials or make; above it, make sure you are paying for craft and not only the name. Today the Van Cleef & Arpels Vintage Alhambra Pendant is the safest buy, and the Tiffany & Co. Return to Tiffany Heart Tag is the most affordable one we would still recommend.

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.
