Hi Adele and welcome to the forum.
What do YOU think about the quality?
Certainly, you've compared these to other examples.

Hi

Yes, i have checked many other emeralds and what confuses me is the concept of impurities.

From what i read green color of Emerald comes from chromium or vanidium impurities and black inclusions of the trapiche from carbon impurities

I have seen other trapiches way greener and with much more carbon so they are full of impurities and I have hard time to connect "quality" with "impurities"

So, I am unable to tell anything about the quality of my stones and that's why i am here, to ask the experts.

Thanks

By comparison to this collection, yours look beautiful. Certainly similar to some of the best above.

Thanks for the images but what do you think of all small black inclusions found in mine making the emeralds look hairy inside?

when too many is to much?

Thanks

It all depends too what you intend to do with your stones.
If you intend to keep them in a box on a white backing as collection items, high domes with strong green emerald color will look fine, high quality.
But as soon as you want to set this kind of stone for a ring or pendant they will look dark and dull and the star might be nearly invisible.
For jewelry, flat slices, not too much colored, will look better and set off the star better.
So the quality might be reverse to what you think at first.
In that way trapiche emeralds are tricky.

Beautiful trapiche emeralds - I like them too.

Many show a nice additional effect - a cat eye in each emerald segment.

Move the stone a bit and the cat eye runs from the center to the outside and back. Six little cat eyes...

Hope your stones are not to flat to see it.

I prefer them with an emerald core like the top left, the third from the left and top right.
