Difficult enough with a lot of light, imagine trying to take close up photos in the dark.
Here you go!


This is under the desk- obviously not "pitch black" but fairly dim. Even though it's in a dark spot, the stone still finds some light to reflect, hungry little fella ( hunger for light )

Now let's hit him with the Handy Dandy Pocket Ultra Violet Spotlight


BINGO- now you can see a lot of detail and wow- it's BLUE!

great new stone D, very beautiful.

Cool photos. And I can testify to how difficult it is to even get the blasted camera to focus in the dark. Never mind actually take a sensible picture.

However, David, you've got to explain this to me. In private, just here in this little thread. No big public disclosure needed. It's not like Lion Woods - no, what's he called? Leopard? Puma? Ah, yes, that's it, Cheetah Woods.

I know you've got big hands, and that you are very dexterous, not least because you are a musician, BUT

One hand to hold the tweezers. Check.
One hand to hold the handy dandy UV LED light. Check.
One hand to hold steady and point the camera. Err...

And you still need another hand to actually press the button and take the picture.

Now, what I really, really want to know is: where are your feet???

BTW- I intend to continue this series with more photos- including some of the weird fluorescent colors we have- and also to add videos.....

Loving that stone!!!

That is just awesome!!!

Some of the melee on a ring of mine have a strong blue flour as well.  I always love it when I go in lighting where they just glow

I wouldn't mind seeing WHITE fluorescence.  That seems odd to me but strangely captivating, too!

Here's the same diamond in sunlight


Interesting how blue fl can dull a yellow diamond's color- while the yellow FL seems to add to it.

...but the pear is yellow fluoro...

I think what David is saying about the dulling is not referred specifically to either of the stones in this thread. I have seen it happen in FIY stones, where it can really take the edge off the yellow; in fact I suspect in lighter yellow stones blue fluoro might actually show the stone to be darker than it is without UV

Ah! I had misunderstood!

Super interesting OMC!  I didn't know that about diamonds.  neato!
