My super rare neon green Russian demantoid, no treatment. It is almost 1ct (0.95ct) and would be about 2ct if it didn't have this spot right in the center. Because of this inclusion the price was good for me to buy my dream stone in this color. It got a very warm welcome in group Inclusions on FaceBook one year ago. I am going to set it since my daughter says she loves the stone for what it is and will proudly wear the piece of jewelry after I pass away.

Another little stone is super rare and very small. Deeper green Russian demantoid, 0.51ct, 4.8mm. The seller loves taking pictures of such rare stones on top of the US dollar bill. Already set in 14K YG cute solitaire ring.

0.46ct tiny Russian Alexandrite. Didn't get good pictures of it.

I've got Alexandrite (of course) Painite, Taaffeite, Jeremejevite, Bixbite, Serendibite, Benitoite, Pezzotaite, Cuprite, Japanese iridescent garnet, Hauyne etc. All were posted years ago but I removed the photos a few years ago when I saw a seller using my images! Don't know if it counts but I've got a very large Pezzotaite also. I guess it depends on what your definition of extremely rare stones is.

This is my new grandidierite. It has the same colour and glow as some of my Paraiba which I was so surprised about. I’m trying to think of a design now! Sorry for the photo - it was a windy day and I took a risk trying to photograph it and in the end panicked and took photos through the plastic!

Ooh. Is the grand faceted? I can’t quite make it out!

 

[LD]

Yes it is. It’s beautiful. It has a slight window but I can forgive it because of the colour! Here’s the sellers photo so you can see it more clearly.

I'm impressed that you can keep it all straight what is what, after you lay them all out like that! As a consumer and not a gemologist, I would be afraid to get the stones mixed up. As it is, some of my jewelers can't tell the 1-1.5mm spinels from sapphire, demantoid garnet from mint/grossular garnet, red rubies from red spinels etc. Is it easier to remember or tell the difference if the different gems are bigger than melee size?

 

[Nosean]

No, this is no problem. As a collector I know each and every stone in my collection and so it is impossible to mix them. I made this video only with the small stones.

Reviving a zombie thread for a new purchase. Although it’s not strictly speaking a COLOURED stone.

I recently bought a 3ct, loupe clean, colourless, emerald cut Jeremejevite.

I know the pale blue ones are more desirable but I fell in love with the clarity and that it is absolutely colourless (no overtones or greyness).

It is currently with my jeweller for setting but when I get it back I will add some pics. Not sure if this is rarer than my grandidierite or not, but am super excited!

 

[Lentibulariaceae]

Ah, the rare gemstone hoarder has found the rare gemstone thread
My current favorite, although not rarest, is my shield cut, 0.49ct Benitoite

The color on this would be considered essentially perfect, and it’s loupe clean too!

What is your rarest?

 

[Lentibulariaceae]

What is your rarest?

Not actually sure! That one is definitely up there, two other contenders off the top of my head:
0.37 ct vayrynenite, from Pakistan. Unfortunately this one has a surface reaching inclusion so it’s not very stable, but it is a fine collector piece!

0.44 ct pastel pink poudrettite from Burma. Most of the (already extremely rare) poudrettites on the market are cut from a large colorless crystal that was found in the early 2000s. This guy is pretty big for the species and an uncommon color, so I’m pretty sure it surpasses the benitoite in rarity.

I’m also currently scouting out a Zektzerite, so that might be our new winner eventually!

 

[AntiqueFreak]

Here’s my grandidierite. I can’t remember the weight but I think it’s between 2 and 4 carats. It’s in the safe right now and I can’t check right now!

Love that vivid orangey pink colour!

Love that vivid orangey pink colour!

It’s so lovely isn’t it! It’s almost as bright as some of my spinels, it’s a shame it cannot be set.

I saw a similar one on thegemtrader.com recently I think - the same one?

Thanks for sharing, bet with that cut its crazy dispersive. I have yet to find the perfect blue one but I have a couple oddity pieces. Here's a bicolor and a heated orange. They are in the 0.6-0.7ct range. The blue is a little darker in real life.

It is that same gemstone, yes! The bicolor is amazing, really interesting little guy.

 

[toomuchB]

Yeah, it has an interesting shallow (but not windowed) shield/oval step cut and several naturals (intact original rough skin) on the underside of the stone which are very cool under a loupe.

Here is the finest bicolor I've seen, 1.83ct with a great split - owned by @poetry_in_stone (instagram account is private, so screenshots instead of a link)

Cool!!

 

[Ionysis]

Finally here!

 

[Ionysis]

You would not believe how sparkly this is in real life. It’s loupe clean and absolutely colourless. I tweaked the CAD several times to make sure the setting was low enough to the finger and the side stones gave finger coverage all the way across. Was so worth the extra attention to detail.

Think this is my new favourite ring!

What an incredible Jeremejevite!
