An Intense-yellow 30-carat Diamond Ring.

First, pay attention to authenticity and rarity. The major auction houses, such as Sotheby’s and Christie’s, stand behind the authenticity of the pieces they are selling; they usually provide gemological certifications. Try to buy from a known and reputable dealer.

When it comes to buying rubies and sapphires, value is based on quality, cut, carat, clarity, condition, and country of origin. For instance, the finest rubies hail from ancient mines in Burma (now Myanmar) and are prized for their clean, “pigeon-blood” red.

In the world of antique, vintage, and estate jewelry, signed pieces by the maker can mean the difference between a lovely item and an appreciating asset. A signed object also makes it harder to knock off. The blue-chip makers remain the standard-bearers: Bulgari, Cartier, and Van Cleef & Arpels continue to be coveted by savvy collectors.
