My diamond turns light violet in the sun....

[ianchang1]

Hi All,

According to the paperwork (GIA + GCAL), my diamond has no fluorescence, yet it glows light violet in the sun.

It''s an Ideal Cut, and I''m wondering whether this has anything to do with this intriguing effect. If so, what''s the science behind it? Can anyone shed some light?

Thanks!

It could be reflecting blue from the sky, this happens a lot. Or you could be seeing coloured light/ fire in the spectral blues.

yap, probably just the sky.

To test fluor, buy a cheap dark light, those that use to test for dollar notes and go to a dark room/closet and shine the light on the stone and see.

If your diamond has fluor it should look like this under UV light. This is an I colour diamond with strong blue fluor.

This is the same diamond in the sun. This is not a reflection from the sky.

This photo was taken indoors with no lighting. You can see the effect the fluor has on the diamond in making it look super blue/white.

In this photo you can see that it''s picking up the blue of the surroundings and it''s not the fluor showing (although I''m sure it looks bluer because of it).

My diamond also does not have flourescence but mine also looks blue in certain lighting. Once a jeweler even asked me if it was a blue diamond.

No clue why - but you are not alone!

Thanks for all your replies. My diamond, though, does not look blue at all. Is it possible to have a diamond that fluoresces light violet?

Could a reflection of a blue sky produce a magenta hugh? I''m just not sure how that would work...the paperwork says it''s non-fluorescent....could both GIA and GCAL be wrong?

To me fluorescence can look violet sometimes. I don''t think the sky or fluorescence could produce magenta, you might see reddish/ pink sparkles with fire or coloured light sometimes but not overall/

Were you wearing a purple shirt when you noticed it

In direct sublight, most ideal diamonds go "dark" and to me this darkenss looks a little bluish/purple at times, probably from the blue sky.

An error is, of course, always a possibility but GIA and GCAL are both capable and reputable outfits. I think your risk that they both screwed up on exactly the same thing is extremely low and it’s reasonable to rule this out.

When you look into a diamond, the reflections you see are of the environment about you. It’s just jumbled up a bit so it’s difficult to recognize specific things. It’s common for jewelry stores to have dark ceilings with lots of bright spotlights distributed about for this reason. It’s not what most of us would choose for our homes but it makes diamonds really zing.

In your case I think it’s likely that what you’re seeing is the colors from the environment around you. Possibly it’s the sky, or your own clothing, or nearby buildings, shrubs or a nearby car. Look around and see what’s there. You can easily test this by simply wearing a different blouse and looking at it in a different place and seeing if you get a different look.

I saw two D cushion diamonds. One with very strong florescence and one without. Photos were taken by a window.

Hmmm good point, it could''ve been the clothes.....then perhaps I should wear transparent clothing, and then my fluorescence worries will be over. Fluorescence for jail time - a fair trade.

But seriously, I''ve heard that diamonds cut ideally can cause this magenta-eminating effect on its own. Is this true? If so, can someone explain how this happens?

Thanks in advance!
