Laboratory-Grown Diamonds: Updates and Identification | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on April 16, 2020.
Diamonds are made of tetrahedrally-bonded carbon atoms that give them the highest hardness, molar density and sound propagation velocity of any natural material on Earth. These unique properties make them significant in the technology sector, but also produce the beauty and rarity that make them among the most sought-after gems.
The demand for such a versatile and valuable material has led to rapid advancements in diamond growth technology in the last decade. GIA senior research scientist, Mike Breeding, PhD, delves into HPHT and CVD diamond growth processes and how UV fluorescence patterns, phosphorescence reactions, and diamond inclusions are among the many clues that help researchers separate natural from laboratory-grown diamonds.

Thank you for the lesson. I now know that my SW/LW UV lamp is very important to identify these.

[@tinah142]

Thanks for the chemistry lesson. As a consumer, I prefer lab grown diamonds. I just came here to learn the differences between HPHT and CVD. I took 2nd year chemistry classes in undergrad and I was able to understand your presentation. Thanks for not dumming it down too much.

Wonderful & informative video! Thank you!!!

[@rarenaturalstones3905]

excellent,much appreciated!

[@tinalleight5255]

This video is so helpful identifying lab grown! Thank you

[@olarhegge8210]

Excellent video,, very helpful

[@aismagiloff]

Thx! Got many interesting facts.

[@ruslanmukhameduly218]

Thank u for such lectures

[@georgepierce4537]

Very knowledgeable and Comprehendable

[@ejalfa780]

Thank you for the education

[@colombiaemeralds]

Great hope one for emeralds!!

[@wiktor-alekswloch8875]

Fenomenal ..

[@sherencorigiano]

Absolutely fantastic session with informative details. Thank You.

[@istitutodigemmologiagenova1976]

Thanks for sharing 🌈🌈🌈

[@stevehawkins5245]

Really hard to hear - had to call it quits. But awesome info.....

[@giovannimarceno3790]

Grazie GIA DIO VI BENEDICA

[@istitutodigemmologiagenova1976]

Giovanni Marceno ci uniamo alla benedizione 🌈

[@tanishqg4053]

Wanted to go back to the molar density of Diamonds. Aren't Osmium and Iridium the densest materials for a given volume??

[@maximhollandnederlandthene7640]

Amazing 🤔

[@user-pv8xj4vj6b]

❤ধন্যবাদ

[@brittnijangrow]

Lab diamonds 💎 for the win! 💍 cannot think of one reason to purchase at mined prices.

[@diaman]

Hello , is there a GIA in Cambodia?

[@jennanylen3617]

good presentation - however the speaker has a terrible connection to the microphone... he sways in and out of range so the volume is very in consistent..

[@HamZa-ew1mr]

Omg omg omg please go for glass filled ruby

[@irwanhassan7312]

I am going to cut and paste on my facebook so people don't get confused.

[@unclefroggyiscool]

the audio is really bad

[@anastacyahdaughter5982]

So true 😩

[@4lifevideo643]

Hello, is it possible to get the subtitle in German?

[@lucianovasco4654]

Bom dia, excelentes aulas. Gostaria de saber sobre o processo CVD, sem a semente não forma mesmo um diamante? A deposição de carbono em cima de outro substrato não formaria um diamante? Obrigado.

[@forestdeshawn180]

you probably dont give a damn but does any of you know of a method to log back into an instagram account? I was stupid lost my account password. I appreciate any assistance you can give me.

[@caseyjeremy1602]

@Forest Deshawn Instablaster ;)

[@forestdeshawn180]

@Casey Jeremy i really appreciate your reply. I got to the site on google and im trying it out now. I see it takes quite some time so I will reply here later with my results.

[@forestdeshawn180]

@Casey Jeremy it worked and I now got access to my account again. I am so happy:D Thank you so much you saved my ass!

[@caseyjeremy1602]

@Forest Deshawn happy to help xD

[@TS-lc9hj]

Can this be reuploaded with captions, please?

[@pongusamanont946]

So all lab grown diamond will have fluorescence?

[@mitchelldavis4517]

Why are impact diamonds not of more importance or desirable than lab grown?

[@Amariellah]

Hello I would like to buy rough cut pure lazuli lapis any idea where I can find it

[@gabbybliss5602]

Opaque Motives great thanks for the info I’m on my way there

[@carolewhitby8531]

gem collector on gemoporia.com

[@GhostTraderz]

So Lab is exactly the same as natural ?

[@taymoormirzadi2982]

Did you even watch the video?

[@Paul-ft4pd]

Yes

[@maan1450]

I like ur vids very informative but very poor audio quality.

[@mikefeng4759]

中文：实验室培育钻石 English：Lab grown diamonds

[@hw5947]

Although very interesting the sound quality is awful and voice sounds automated.

[@baileymay5476]

I love my lab grown diamond

[@regnummer]

Can you repeat that?

[@MrCGangsta]

funny how the best meterials are abundant on earth almost like its all pre planed

[@mikefeng4759]

GIA verification of diamond cultivation in the laboratory lags far behind IGI

[@geoffgeoff143]

Ok but in no man's land as far as technical level goes. Few errors. Poorly scripted

[@kcwizard72]

"Be worried you have a lab grown diamond" Why be worried? What if I just want to know? Sounds biased against lab grown diamonds...smh.

[@user-kpkxgtj]

Maybe the "worry" is due to fear of paying natural diamond prices for a lab grown stone? That being said many who benefit from the diamond trade do seem biased in favour of natural diamonds.
