The facts
What queen Conch Shell actually is
Mineralogically, queen Conch Shell is shell of the large Caribbean gastropod Aliger gigas, used for carving, beads and cameo — Crossed-lamellar aragonite CaCO3, crystallising in the aggregate system.
The colour is caused by carotenoid-type pigment in the pink lip. That is worth knowing because it determines what heating, light and time can and cannot do to the stone.
A refractometer reads 1.50-1.68, and the specific gravity sits near 2.78-2.90; cleavage is none.
Where queen Conch Shell comes from
The recognised sources are Bahamas banks, Turks and Caicos Islands, Belize, Honduras and Jamaica and Florida Keys, USA (harvest prohibited).
Origin affects price in this material, so we name the locality on every quote rather than the country. "African" or "Asian" tells a buyer nothing.
How queen Conch Shell is treated
CITES APPENDIX II - the shell, the meat and conch pearls all require CITES documentation to cross borders, and this catches tourists constantly. Florida bans harvest outright; several range states have moratoria, and CoP20 (2025) again reviewed queen conch trade. Colour fades in sunlight. Untreated as a rule.
None of this is a problem when it is said out loud. It becomes one the moment it is left out.
What queen Conch Shell is confused with
The usual confusions are Other pink shell, Pink coral and Dyed shell beads.
The separation is rarely a matter of opinion: refractive index 1.50-1.68 and specific gravity 2.78-2.90 settle most of it in a minute, and magnification settles the rest.
What queen Conch Shell is used for
Queen Conch Shell is bought by carving and sculpture, jewellery, decorative objects and mineral collecting — and each of those trades wants a different form of the same material.
We quote each application in the unit that trade actually buys in, by the block, by the carat or by the piece.
Durability and care
Hardness 3-4; cleavage none. That combination decides what it can safely be set into.
Below about 5.5 a stone will be scratched by ordinary household dust, which is largely quartz. That does not make it unusable — it makes it a pendant, an earring or an object rather than a ring worn every day.
Warm water, mild soap and a soft brush. Avoid ultrasonic cleaners on anything fracture-filled, stabilised, dyed or visibly included.
What queen Conch Shell costs
Indicative pricing for queen Conch Shell is $10-60 per whole shell where legal; carved cameos and beads $30-500.
That is a range, not a quote. Colour, size, clarity, cut and origin move the figure a long way inside it, and the only honest price is one given against a specific stone. Send us what you need and we will price it.

Bahamas banks, Turks and Caicos Islands, Belize, Honduras and Jamaica and Florida Keys, USA (harvest prohibited). Origin affects price, so we name the locality rather than the country on every quote.
Is queen Conch Shell hard enough to wear every day?
Not really. At 3-4 on the Mohs scale it is softer than the quartz dust in ordinary household dirt, so it scratches with wear. It suits pendants, earrings and objects better than a daily ring.
How much does queen Conch Shell cost?
Indicatively $10-60 per whole shell where legal; carved cameos and beads $30-500. Colour, size, clarity and origin move the price a long way within that, so treat it as a range and ask for a quote against a specific stone.
What is queen Conch Shell confused with?
Most often Other pink shell, Pink coral and Dyed shell beads. A refractive index of 1.50-1.68 and a specific gravity near 2.78-2.90 separate it quickly.
What is queen Conch Shell used for besides jewellery?
carving and sculpture, decorative objects and mineral collecting. Each of those trades buys it in a different form and a different unit.
