Facts, Fiction, and FAQs – Exploring Nuances of Lab Grown vs. Natural Diamonds

Thanks a lot Garry for sharing.


she said "...so actually this is pretty true, a blue fluorescent diamond must be a natural diamond..."

So this is completely wrong and CVD diamonds can have blue fluorescence because of N3 impurities, it's rare but not impossible (For sure there will be growers that will try to grow Blue fluorescent CVDs more and more)

It's a yes and no issue V.
In my playing around the key difference is the frequency and intensity of the LW UV.

But the concept she described is accurate.

Thanks Garry,

Do you mean under different wavelengths and intensities of UV light we might see the blue fluorescence of a CVD diamond?

I mean CVD can have pure blue fluorescence, the color of fluorescence I consider important not the wavelength

Am I right?

When we upgraded last summer to 2ct D Si1 i made sure it would be easy to id as a Natural - saved a bit $ too with the Strong FL

Yes, different reactions to different frequencies V.
And unlikely you would get a synthetic piece like FreddyBostons just posted.

Thanks @freddyboston and Garry,

Although rarely CVDs can have blue flourecence but it's not imppssible.

A few melee CVDs with blue flour. I saw in person and this material will be found more and more.

I remember the time that there were no IF/D CVD diamond in the market.

Nice ring you have @freddyboston

How much damage have your 2 rings caused each other so far Freddy?

 

[freddyboston]

So far so good Garry - wedding ring is thinner / diamonds sit lower than new e ring (beefy 3mm) plus wedding has looser size so can wear higher up finger to give some separation. Didn't want to Solder and not a fan of spacers.

OK, you are aware of the risks. A spacer of any metal will be required as the platinum will not be worn away, so even a cheap thin white gold will work.
Do you have a loupe to identify the damage.
Nothing you wrote would make me comfortable.

Thanks Garry - my wife's stubborn - says spacer would put too much metal on her finger - i asked her next time she's visiting the local jeweler to ask them to take a peek - if there is problem maybe they can convince her.

Dont wait a day - buy a loupe -
I've seen the needle and the damage done
A little part of it in everyone
But every junkie's like a settin' sun

Happy to report I was able to convince her Gary and placed an order for a spacer today. Since i have your ear - I'm curious your thoughts if there will ever come a time when certification labs start looking at transparency as part of the clarity grade ? Our Si1 got hit for the table crystal (scary at magnification / eye clean real life) Were not for that it's a remarkably clean and bright stone.

Re transparency: my book soon to be out. It has two themes. Cut quality and light performance AND transperancy.
I am also writing an article for gemologists publication with a scientist friend on haze in diamonds including blue fluorescent stones.

My type of diamond. If the crystal was off to the side it can still be SI1 if it's quite a bit larger. And being near the top of the stone there are little to no other reflections of it.
