Light, but not full sun

The faces take the light one at a time, so a point on a shelf changes through the day. Keep it out of direct sun though: amethyst and rose quartz both fade.

Named, treatment and all

Undyed is written undyed. Where the colour comes from a metal coating, the page says so, because that is the part nobody else tells you.

No two points alike

Banding, colour zoning, a tip a degree off centre. That unevenness is what tells you it is stone and not resin, and it is why yours is yours.

Frequently asked questions

What is apatite?

A phosphate mineral, found in blue, green and yellow. The blue variety is the one usually cut for display. It is the same mineral family as tooth enamel.

Is blue apatite fragile?

Yes - noticeably softer than quartz, around 5 on the Mohs scale, and it scratches easily. It is a display stone rather than one to carry loose in a pocket.

Is the colour natural?

Apatite is naturally blue, though heat treatment to deepen colour is common in the trade. We cannot tell you which applies to a given piece.

How should it be cleaned?

A damp cloth only. No ultrasonic cleaners, no heat, no household products - apatite is sensitive to all three.

Cut from rough, not grown

A tower starts as a block of rough stone. It is sawn to a rough shape, ground to its faces, then polished by hand through finer and finer grits. The faces are never perfectly equal and the point is rarely perfectly centred - that unevenness is what tells you it is stone and not resin.

What the colour is telling you

Some of these stones are exactly what they look like. Others are quartz with a metal coating applied under heat, which is where the iridescent blues and violets come from. Neither is a lesser stone, but only one of them is a natural colour, and we say which is which on every listing.
