A Laminate usually surrounds the diamond on the outer surface,until it is remove by grinding or picking the laminate off by hand. It's like slag or the impurity's that have been pushed to the outside edges that surrounds the diamond

[@mikesamen7472]

When you apply a UV light on a rough diamond, do you see any electron moving inside it?

[@ThirteenPercentHxC]

Hello im an artisinal gold and diamond miner in southern California. Ive discovered a local diamonddiferous kimberlite pipe and have the specimens to prove it. What should i do?

[@leahtramble9608]

Everything you guys described and explained in your lecture. Your presentation says that I have 2 diamonds. I'm looking at them with magnification 2 diamond magnifiers. I have a diamond tester and it also says. They're diamonds and is. So I guess the only thing that will certify my curiosity and confirm is to take it to a GIA specialist. I don't have any technical questions per say , however the frosted the groves and bubbles the platelets are all there..

I have come across POINTS NAIVE DIAMONDS. Here in India, the IGI, GIA and other diamonds examiners, PROBABLY NOT READ AND UNAWARE OF OTHER METHODS OF TESTING. ie Spectrometers, Refactometer

[@Kumars-Rocks-n-gems-show]

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

Do the irregular and ballas shapes break or cleave? Or do they cleave irregularly or crush, or is there always cleavage?

[@JoseEduardoEguiaGonzalez]

Me podría hacer favor de comunicarse contigo creo que te agradecería ver qué es

[@mitchelldavis4517]

a lot of the minerals in Arkansas fit every of these descriptions. Are these all diamonds?

[@solimanel-deeb8922]

Yes. Run Mitchell run, grab 'em all.

[@karent7460]

I have rock test possitive dismond I need help

[@gloree5751]

I have a coaches found in Kimberling. the man. rolled over and brought the diamonds up. my problem is these stones have a dual refractive or they give a dual pocket on xray. the overlay of the optical property's prevents the light spectro from reading the stones properly. this also with laser focused through the stone shows layering that makes holograms. I need to get these certified. and they maybe needed for optical advancement. they pass all old tests but they don't work on the new testers.

Interesting. Tell me we're you ever able to get proper insight? Where would one go to sell a major diamond discovery in size and to reveal a undiscovered region that is diamond rich unbeknownst to the local population of that area? Thank you for your time and help. I also have a bunch of diamonds, meteorites and Dino skull fossilized that reads as diamond on my digital tester yet is too big for me to do my normal gravity test. Most ones I find have a purple glow under a blacklight. One of the meteorites glows a strong purple with the porous center glowing bright pink with holographic features. Before I broke a piece off when flashing g with a cell camera it completely looked different in shape and look. It shined like a bright clear Metalic diamond shaped like a rabid or ferocious looking chip munk or alien head of some sort but menacing about the size of my hand or say a grapefruit size. I can be contacted at [e-mail] or text me at 410-924-0397. Also have what I believe is sapphire but very large slab turning from blue to red at one half side. It's about the size of a roomba self driving vacuum cleaner and veryheavy/dense. I have a greenish orange meteorite football size with diamond looking features but can't definitively say for sure. I really need to find a appraisal source familiar in rough uncut diamonds , sapphires, and meteorites. I am willing to sit 50/50 the proceeds derived from any sales obtained from the selling of any stone or item I have with someone willing to partner with me with knowledge and/or resources to facilitate the appraisal and categorizing correctly of my collection and sale or leading to the selling of anything mentioned. Arbitration welcomed and rewarded handsomely if you don't fit the bill but know another who may have the abilities needed and can run with the ball to score. Any insight welcomed. Also looking for a parasitic dr for correct diagnoses of the parasite I've been infected with that local drs have no experience in testing for or diagnosing or treating and would prefer to turn the other way and either misdiagnose or label as fear of parasites chalking up as purely mental without any due dilligence based purely off opinion , speculation, & assumptions at the risk of my declining health. God bless all of my fellow rockhounds out there.❤
