Is it ethical to buy coral jewelry?

Buying antique and vintage coral reuses material harvested generations ago rather than creating new demand. We do not commission new coral pieces.

How do I care for coral?

Keep it away from perfume, acids and ultrasonic cleaners, wipe with a soft dry cloth, and store it separately because it scratches easily.

Are there import restrictions on coral?

Some coral species are subject to international trade rules. We check every piece before shipping to the United States and will tell you if anything affects your order.

Loose colored gemstones including sapphire, emerald, opal and garnet on a paper parcel — Coral: what it is and what you can bring home

In short

Precious coral is an organic material, the calcium carbonate skeleton of marine coral, about 3 to 4 on the Mohs scale. It was carved and worn throughout the Victorian era and revived in Art Deco and the 1960s. Modern harvesting is regulated, which is one reason antique and vintage coral is the responsible way to buy it.

Coral is soft, warm and easy to carve, which is why Victorian workshops turned it into cameos, beads, roses and hands.

Buying antique coral means buying material that was harvested long ago rather than adding pressure to living reefs today.

An organic material

Calcium carbonate laid down by a colonial animal, carved rather than faceted, and soft enough to bruise against a diamond in the same box.

Species and group: Organic, calcium carbonate. Mohs hardness: 3 to 4. Typical colors: Pale pink through salmon to deep oxblood red, plus white and black.

Fine, parallel growth striations are visible under magnification on genuine coral
Soft enough to scratch easily, so antique beads often show wear at the drill holes
Sensitive to acid, including lemon juice and vinegar, which will etch the surface
Deep red oxblood material is the most sought after in the antique market

Dye, reconstitution and imitation

Coral has been imitated for as long as it has been fashionable, in glass, in dyed bone and now in resin. The tests are simple, but they need to be done.

Our gemologist examines every stone before a piece is listed, and the description states what is known and what cannot be determined without a laboratory report.

Dyeing of pale material to a deeper red: common and disclosed when detected
Waxing or resin impregnation to improve polish
Reconstituted or bonded coral powder is sold as coral and should be identified as such
Glass, plastic and dyed bone imitations are widespread in costume jewelry

Telling coral from its substitutes

Look for growth structure. Real coral is grown in fine parallel lines, and almost nothing that imitates it manages that convincingly.

Genuine coral shows fine parallel or wavy growth lines under a loupe
Plastic imitations have mold lines, air bubbles and warm instantly to the touch
Dyed material often shows stronger color in cracks and around drill holes
Genuine coral is light for its size compared with glass

Victorian coral, and a note on provenance

Nineteenth-century Italian workshops, especially in Naples and Torre del Greco, produced most of the carved coral found in Victorian jewelry, from cameos to naturalistic branch brooches.

Coral returns in Art Deco pieces beside onyx and jade, and again in 1960s gold. Our pieces are antique or vintage material; the age and any visible dye are stated in the description.
