How to recognise a genuine Saint Lucy’s eye
Two different opercula circulate under the same name. Telling them apart saves you paying Corsican prices for a tropical charm.
First of allNeither a stone nor a shell
Saint Lucy’s eye is an operculum: the small calcareous door a sea snail closes behind itself for protection. The Mediterranean one comes from the rough star shell, Bolma rugosa. Polished on one side, it reveals a spiral resembling an eye — hence its name and its reputation for warding off the evil eye, the ochju.
No animal is taken for the operculum alone. Some are gathered washed up on the shore; others come from shellfish caught for their meat.
The testSolid, never hollow
This is the simplest and most reliable criterion. A genuine eye is a solid, dense piece of calcareous material, surprisingly heavy for its size. A resin imitation sounds hollow, weighs little, and often shows a spiral that is too regular — drawn rather than formed.
The white face proves nothing: it is the result of polishing. In its natural state, that side tends towards dark.
The real questionMediterranean or Pacific?
Both are natural, and both are sold legitimately. But they differ in origin, in rarity and in value. The problem begins when the second is presented as the first.
| Saint Lucy’s eye (Mediterranean) | Shiva’s eye (Pacific) | |
|---|---|---|
| Shape | Rather elongated, fairly flat | Thick and rounded, domed |
| Colour | Spiral tending to orange and pink | Grey, green, brown or white tones |
| Size | Rather small | Often noticeably larger |
| Availability | Rare | Common, imported in volume |
Our rule. We sell both, and we always say which is which. Many sellers present Shiva’s eye, the more common one, as a Mediterranean Saint Lucy’s eye. We do not — it is a matter of honesty, and it is also what sets us apart.
Frequently askedWhat people ask us most
Mine is grey-green. Is it a fake?
No. It is very probably a Shiva’s eye from the Pacific — a natural material too, simply from elsewhere. It is no less beautiful; it is just more common.
Can I collect them on Corsican beaches?
No. Sand, pebbles and natural material on the shoreline belong to the public maritime domain: removing them is not permitted. It is little known, and widely ignored, but that is the rule.
Is it a precious stone?
No, and the term would be incorrect. Saint Lucy’s eye is an organic jewellery material, like mother-of-pearl or coral. Gemmological terms are regulated and do not apply here.
How do I care for it?
There is nothing to do. It is polished to shine and may take on a slight patina over time — that patina is part of its charm.
What metal is it set on?
Depending on the model: silver, gold plate, gilded brass or steel. The label always states it, and for precious metals the hallmark is the guarantee.
The test takes three seconds, in your hand. We show you both side by side — the difference is obvious once you have held them.
