Let's play a game... rainbow gems.

[PrecisionGem]

Here are some rough Spessartine Garnets from Africa. The far right is what is now mostly being found in Nigeria, which is more of a burnt orange, and some are even more red.

Loving the crystal on the far left! I always enjoy seeing our favorite stones in their rough state.

YELLOW is next!

 

[PrecisionGem]

Here are 5 different yellow stones. Stones you don't often see. I leave it up to the group to identify them, at least for a few hours before I edit a picture with their identities.

Ooh, I love games! Is the greenish yellow one a titanite? Could there also be danburite in there? Just guessing

How fun! I’ll guess sapphire, helidore, Mali garnet, yellow grossular garnet and chrysoberyl. I’ll take one of each, please

I like the game too

I like the guess on the greenish yellow rough being sphere~ But I would also guess it is a Mali garnet?!

That yellow colour on the far left stone is bright and intense, that makes me think it’s not sapphire as many yellow sapphires don’t seem to get that level of saturation. However it’s also not the general shape of tourmaline, so…Helidore due to its more honey hue.

Those on the far right… do remind me of typical chrysoberyl.

God, I have no idea on those on the right of the green yellow one..!

I had the same thought, and decided to go with sphene just for fun.
I was also trying to make sense of the clue that they are “gems you don’t often see” - that seems applicable to both.

 

[PrecisionGem]

No Sphene and no Mali Garnet and no Helidor or Chrysoberyl. Had I thought of those I would have included them in the photo, so good guess.

Since those gem types are ruled out, does that mean the other guesses we’re right? If so, that would mean there are danburite, grossular garnet and sapphires in the picture. Possibly the sapphires are from Montana since you mention they are stones you don’t often see.
For the other two I’ll guess yellow zircon and yellow tourmaline.
This game is harder than it looks .

And before we move to green, I just want to contribute my own Fanta~ ORANGE

 

[Crimson]

Wild guesses Brazilianite? Yellow apatite?

Here's my (very) random guesses... sapphires, citrines, chrysoberyl, and the last two groups could be topaz (or beryl) and tourmaline?

These are great guesses... haven't looked at the answers yet!

 

[Autumn in New England]

I only got one right so far!

 

[PrecisionGem]

The two big stones next the the danburite are Scapolite from Tanzania. The other stone with the green cast is a quartz. They call it lime quartz.

Yay! Thank you, Gene for a game within a game.
Now it is time for GREEN.
I received this. I think it is a cat’s eye chrysoberyl. Does it look like a chrysoberyl to you? it is set in 22K gold.

Me too I went too far with the clue that the stones are not what we’d encounter often. Otherwise I would have guessed scapolote.

Are lime quartz and lemon quartz the same thing?

 

[Daisys and Diamonds]

@PrecisionGem that lime quartz looks yummy
is it made into jewlery ?

Thank you, @Daisys and Diamonds I think it is quite an old piece, judging from the design of the chain and the setting. It gives me warm, old-world feeling.

You are right, I meant lemon quartz. For some reason I always get limes and lemons mixed up. Last time my wife sent me to get a bottle of lime juice, I brought how lemon juice.

As far as the quartz goes, these are also know as Ouro Verde quartz. It's irradiated with cobalt-60 gamma rays and then heated. Usually starting out with clear quartz.

Yes, it looks like chrysoberyl to me.

It doesn't look like the artificial (fibre optic glass) cat's eye in this thread - it's clearly better cut and polished:

Note especially the last post, showing the flat back with striations.

That said, many minerals can show cat's eyes. As always, you can't tell from pictures. The 22K gold setting is a good sign (against that, the stone could have been replaced...). FWIW, my gut feel is that it's chrysoberyl.

 

[Starstruck8]

Blue: Labradorite, inexpensive but with fascinating iridescence. This specimen seems to be a single crystal (because the schiller plane spans the whole surface).

Thank you, @Starstruck8 You are so knowledgeable about gem phenomena!

and our rainbow. in back after a bit of a sluggish patch
pink is next
thanks to @Starstruck8 @icy_jade and @Nick_G

you know i can't help but think of all those rock hounds who pop up out of nowhere hoping they have just found something really valuable on the beach or out of grandma's button jar (i did see an antiques roadshow once where someone actually found a tiny faberge egg that way) and now we have the perfect thread for their finds regardless of what they turned out to be ( ....well so long as its a real stone)

its not very often on PS all natural gemstones get to hang out together like this and it makes this a very intetesting and pretty thread

here is something red i wish i had more off
the NZ $100 note
that's Lord Earnest Rutherford
he was the first person to split the atom
that's a yellowhead on the back

 

[Daisys and Diamonds]

opps its pink and i posted a red note
honestly that took way too much effort to just delete that post

 

[Daisys and Diamonds]

so back to something pink...
i scratch my head trying to think of something pink
but i had this poster on my bedroom wall as a kid
its Jessica from Logan's run - the tv series


i just watched the movie on netflex and was shocked Jessica was in a green dress and was played by Sister Julianne from call the midwife
