Moody stones: Post them here!

[oncrutchesrightnow]

Wow! That's an amazing range of colours!

I have to say that the range of background colours (presumably all the same skin) suggests inconsistent exposure and white balance. Do these colours match what you see?

Yes, these are the colors I see under different lights. Best I can remember… bathroom, bathroom, daylight, airport, airport, back porch light, bedroom, back porch light, morning daylight, front porch light, morning daylight, back porch light, back porch light, the rest are afternoon daylight (IIRC). But I may have gotten some of them mixed up. This stone is crazy.

Here is how it looks most often


And then in bright sunlight under just the right angle… matte black


GIA says dark brown pink. IMHO there is purple in nearly every light. My understanding is that GIA does not list color modifiers if they make up less than 15% - that is one explanation for not listing purple.

I took a chance based on Leibish’s excellent photography, customer service, and return policy. Here is a still from their video. This is the image that sold me… I see pink, orange, brown, and purple.


I was so happy to find that notwithstanding the lack of purple modifier in the report, this diamond is more burgundy than maroon.

I am going to check the rating on my front porch light and then carry a flashlight around in that particular wavelength because no way did I expect to see that kind of purple.

Thank you! Amazing stone!

As others on this thread have noted, red/pink/purple garnets are notoriously shifty. I'm thinking that this stone may have a similar absorption spectrum, though no doubt for different reasons. It's very impressive to see these shifts in a diamond.

Thanks! I don’t want to hijack the thread but have read some interesting articles from GIA on color shifts in pinks. blues, violets, and greys.

Here’s a fun pic:

Great example!

I'm thinking this may be one of the articles you mentioned:
https://www.gia.edu/gems-gemology/s...-blue-gray-violet-diamonds-allure-of-the-deep

Note the section titled Hydrogen, especially Figure 6 and Figure 7. This seems to fit your stone very well. See also Figure 12, which says that in almost all violet-ish diamonds, the colour is caused by hydrogen defects.

I have zero clue what color this diamond is except “not green.”

I would call it "chameleon diamond"!

Thanks for taking the time So the violet (i.e dark purple) seen under certain lighting conditions could be hydrogen lattice defect... The brown-pink seen almost all the time could be graining typically seen in many pink diamonds? When it turns black it is almost like having two polarized lenses at 90 degree angles. Maybe the hydrogen defect and the graining are “interfering” somehow? Anyway I bought this stone because ooo pretty but the science is kind of interesting.

This is a spinel band I bought off LT, it is quite the moody one but most of the time I see it as light pink/periwinkle shade.

oncrutchesrightnow, that thing is nuts. As in amazing, never boring, find another one like it nuts.

Thank you all for humoring me!

This moody spinel needs its own stash of Midol

Thats also a very moody no heat sapphire. Very tiny bit milky and goes as more intense blue as more sun he gets. Very unusual "behave"!

I'm obsessed with this sapphire. I've been chasing it's equivalent for what feels like forever. Hopefully, I'll find one someday because this is right up there for me in perfection

This is one of the coolest stones around- it's like having at least five looks at any one time in one ring. Any stone lover would flip!

But I'll start. Here's my opal. Opals love directional light. Top, hero pic in light from a distant window - soft but directional (see shadow). Below, under a cloudy sky. Still shows colour, but much less vivid and lively.

More googling, more questionable results... But all reputable pages seem to reference this article - which I've just started to read but seems like it will (actually) answer a lot of the questions we've been tossing out. Interested in your thoughts if you have time to read it! Starts on Pg 34 - Frozen Opal Fluids and Colloidal Crystal Fire: Gem Opal Deposits in the Heart of Australia

Sapphires invented moody. They own it.
