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 yooperlite?
A syenite rock containing sodalite, found on the shores of Lake Superior in Michigan. The name is recent - from "Yooper", the nickname for people of the Upper Peninsula.
Why does it glow under UV light?
The sodalite within it fluoresces orange under long-wave ultraviolet. In daylight the rock looks ordinary and grey, which is what makes the effect striking.
Do I need a special lamp?
Yes - a long-wave UV torch, 365 nm. Ordinary blacklight bulbs and phone screens will not do it.
Does it glow on its own?
No. Fluorescence is not phosphorescence: the rock glows only while the ultraviolet light is on it, and stops the moment you switch off.
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.
