Amethyst will not photograph true to colour. What ever the time of day. Why not? Any suggestions please. Ginna

Do you mean natural amethyst crystal? Highly reflective surface. Can you back-light?

Other stones photograph perfectly normally. Yes it is a purple natural amethyst, but comes out blue. These are set in silver by my husband who makes silver jewellery for a hobby.

Perhaps if you posted some examples and included the equipment, as well as lighting, you are using, someone here could help.

I suspect the difference has to do with light reflecting internally off of the silver mount.Other stones photograph perfectly normally. Yes it is a purple natural amethyst, but comes out blue.

What is your lighting source?

Night light and then indoor daylight were my light sources. Have had no trouble with colour shift photographing other stones set in silver - a similar pendant with green amethyst and a cabochon star ruby set as a ring.

If it allows for it, try playing with the whiye balance settings to compensate for the color shift, it should help.

Two statements from Wiki (because nobody believes me when I say it):
Amethyst is a violet variety of quartz often used in jewelry.
Pure violet cannot be reproduced by a Red-Green-Blue (RGB) color system, but it can be approximated by mixing blue and red.

Ginna, try the RGB settings below (from Wiki) for a close approximation:

Purple is a very difficult color to photograph. My son's football uniform was purple and my D70s never got it right. Tom Hogan sent me an explanation which I'm sure you can google. I understand high end cameras i.e. D800 get it right.
