what this tweezer called? i need one

This weekend we’ve been screening and picking little sapphires from a Helena mine and I was thinking about adding them to pottery pieces. Is it possible? Is it done?

Great video, thank you

It's a torture to listen.

Smit, how the yellow is in diamonds are caused by nitrogene. cause, she say it is not, in the video titled "Where Do Yellow Type Ib Diamonds Form in Nature? | GIA Knowledge Sessions Webinar Series" .

Superbe WoW

The reason these stones have cracks is that they're "hard"! 😱 Anything thats hard "will" crack. 😳

Sorry but the shape is the swan shape you mention at 17:03 - 17:28 I believe. It is the triangular head and tail coming from it

Great informative video. Thank you for your due diligence.. I would like to speak with you possibly to introduce a new concept I have stumbled across by accident but is life & history changing. I have on video proof of another way diamonds in nature are formed. Amazingly enough it doesn't take millions of years as believed. I've seen it done overnight. This was done by a translucent worm like parasite that is intradimensional. I know, I know, believe me it sounds like a mad man ranting but I have the proof both in video and still images taken from this video. A portal the size of my hand opened on the hood of a car and this parasitic translucent worm comes through contorting itself into the shape of a serpentine looking skull head . I've also noticed before the repetitive snake or dragon looking shapes within the shape and sometimes internal structure of both diamonds as well as other crystals and minerals. I theorize these worms infected dinosaurs with their huge mass and as they died and became extinct and buried there was a layer formed of them and eruptions shatter these groupings pushing them up in what we call kinderlite pipes. I have been infected by this parasite myself and when using blacklist they glow blue under the skin

I appreciate it! Thank you guys for your good job 👍 😊

excellent presentation

Thankyou everytime for your teaching and sharing,Sir ! Very helpful for me learnig about diamonds and other gems.😍

Ye kaha pr hai

Do you like to buy

I have some stones different colours

Pyrite is desirable in Lapis Lazuli...it helps establish authenticity....fine distribution is great... streaks less so... Calcite is not good, it weakens the stone and distracts from the colour...

Boa noite... Tenho 90% de certeza de ter uma Safira amarela ou incolor ..em estado bruto. Densidade testada . 3.94 Peso real 115 g. ( 515 CTS) Totalmente translúcida... Como obter contato de credibilidade com vcs ???

Natural diamonds are not rare in nature

so GIA can take any stone they want sent in for testing , call it radioactive, and pretend that its the government that took it ? that is SO bad

Wow Excellent

聽說有一度燒（一次燒）、二度燒（二次燒），真有這種情况嗎？燒過以後裡面的雜質沒有了，那麼裡面看得到有雜質的還是完全乾淨的才是有價值的呢？

У меня тоже есть не гретый фиолетово- синий танзанит , 12 ct. Я его очень люблю. Он всегда разный , он живой .

Where can i get a gia certificate for a big colored diamond in Europe? I'm from the Netherlands.

Is there kimberlite in cracks of a rough diamond like a small strip of yellow in a crevas

Olá Edu, sou Kennedy Oliveira, Sou da Secretaria de Mineração de Pindobaçu, adorei o seu trabalho sobre Serra de carnaíba, gostaria de ter o seu contato, para discutir assuntos de vosso interesse…

How much?

👍

A culet! <gasp!>

I must criticize the lack of objectivity and clear bias of the GIA. Whether synthetic or natural, a diamond is a diamond. This video looks like an ad campaign

Sir, if someone wants to get his stone tested, how can he get it done from your lab? I am Vijay Pratap Goswami from India. Sir, please give me information about this subject. It will be a great favor to you. I have created a channel of my stone on RUclips with the ID of which like and comment. done this is my id

Very nice video

Would you agree that, GIA doesn't know how large diamonds are formed. GIA doesn't certify the names of mineral inclusions, GIA doesn't have knowledge on points naive diamond s of RAMULA KOTA. GIA DON'T INFORMATION on latest diamond mines. GIA DON'T HAVE EXACT INFORMATION on diamonds with less than 3.25 specific gravity. The certificate being issued by the GIA ARE NOT SACROSANCT IN MANY WAYS.
