I could bring to identify if you based in UK ( London - Birmingham )
I've got too many gems but my knowledge is very poor
I am warring about if any of them has some value
thanks

Don't worry too much. I see nothing in those photographs that I think will have a high value.

The possible exception being the native cut ovalish blue stone (next to the oval yellow stone) at the top if picture two. That looks like it has the potential to be a natural sapphire. Take it to a local Gemologist to be tested.

I responded to a question on Reddit yesterday, (very similar inquiry with a pic of several unknowns).
Quote:
I happened to stumble on some cheap cheap cheap copies of Gem Identification Made Easy by Antoinette Matlins.

https://www.alibris.com/booksearch?keyw ... 26&hs.y=38

Although the book is not a substitute for a GemmRaman (cough cough), it will give folks the tools to offer additional solid information along with posted photos.

If you have a couple dollars to spend, I'd scoop one up before they are gone.

Looking closer at the stone I pointed out as potentially a sapphire, I see what looks like color concentrations at the facet junctions. This could indicate that the stone is diffusion treated, or could just be an artifact of the photograph.

Any competent Gemologist can confirm and explain this to you.
