I'm sorry, but I think the person who shouldn't comment more is you.
Whoever acts and writes like this, completely discredits himself.

my one comment was uncalled for so I apologize for that rudeness. But that’s it.
 
What an amazing diamond! I think stop wasting your time with us idiots and pay to have it certified. I’d fly to a gia reporting center, definitely. Then get the most extensive report. Money is no object, this’ll be millions. You should definitely invest in yourself here- you’ve done the research!!

Definitely needs insurance before sending to GIA. The policy for a 7.5 carat green diamond should only come in around a modest $600k or so.
 
Obviously OP is either having a laugh at our expense, or has decided (against all logic and proof) that he or she has a green diamond rather than obviously synthetic spinel/YAG. Either way, this thread is pointless.
 
The replies sound like Chatgpt.
 
How valuable is a 7.50 carat fancy green / old european cut diamond?
This type of "reverse chameleon" diamond instantly turns white in dark light, but green at daylight.
In incandescent light it has a blue-gray appearance.
Possesses intense fluorescence, like kryptonite.

Hi,

It's for long time ago but anyway

for measuring specific gravity a person gonna need an accurate scale and a glass of water and a calculator

specific gravity is accurate enough for the first assessing

also never trust regular diamond testers in the market especially those that measure the hardness, but real accurate testers are good too

this does not seem to be a diamond but at least you should find out what it is and try your chance.

don't recommend to give this kind of thing to a person to test it for you, maybe you get really lucky and it's a diamond (but I don't think so)

Hi sir!
I'm sorry to reply to you now, I hadn't seen your message.
Thank you very much for giving me your advice.

The density test confirms that it is a diamond.
A very rare diamond, with an alexandrite effect // not a chameleon diamond.
Its color changes with different types of light: Sunlight, bright light (LED) and incandescent...

I think with your mounting data, it would be wise to consider sending the material in for formal testing.
 
You suspect that you have a natural green diamond of THAT magnitude, yet you still haven't consulted with a graduate gemological appraiser and sent it to GIA for grading?
Why?
"Why" is the only question that needs an answer, at this point.

Hello!!
I'm not in any hurry to certify it and I'm not going to send anything by mail either, when it's less cold I'll go visit NY:)
I don't need the money so, in fact I prefer to look at it from time to time because it is hypnotizing.

I contacted one of the best and he advised me, same thing.Screenshot_20240220_153337_Gmail.jpg
 
Round 2... 3???
 
I can't tell if you believe this or you're trolling?

Well, even if you don't need the money, then that is not the point at the crux of the matter: you get such a diamond graded and appraised so that you can properly insure and store is safely, for as long as you own it.
Anything short of this for a single diamond assuredly worth well into double-digit millions of dollars is quite irresponsible, in my humble opinion.
What I truly think is that, at the heart of the matter, you may suspect that it isn't truly a diamond and you don't want to face the disappointment of having that fantasy shattered.

or boredom, confusion/delusion.
 
Did you grandmother tell you how she obtained it? Did she own any other especially wonderful pieces?

I assume you're just enjoying it and not needing paperwork right at this moment. Are you keeping it loose around the house? Or planning to set it after it's certified? I'm just curious over here.

My grandmother spent the last 10 years of her life with Alzheimer's....
I deduce this was a gift from my grandfather to my grandmother.
They kept some of their parents' jewelry, for example this Victorian Daisy ring / Circa 1860 or this Ottoman pendant from early 18th century:)
Antique&Ancient jewllry is the best

Well, when I have it certified, depending on its market value I will sell it loose.
 
Antique jewelry is one thing; green diamonds are in a completely different class. No one would cut a green diamond like that as it would be too valuable to waste carat weight on that cut. If you really believed it was diamond, I am sure you would have already been to the GIA lab for analysis. ‘Nuff said - show us the cert when you get it!
