While the Ari system testers are somewhat useful, they are expensive and in the end we have large numbers of questionable stones that need to be sent out to the lab. Not ideal ! The New mossanites are tough to ferret out, the doubling and side pipes have been greatly reduced. Those of us that hunt down jewelry for resale at auctions and shops are in a difficult place now.
Hey! I agree with your thoughts on the Ari. Regarding the new synthetic moissanites... I have not heard before that their BR is reduced.... do you know the new BR value, or how/why this is happening?
@@TheGemAcademy Forever Moissanite company produces the hardest ones to ferret out, but no idea how they accomplish that. New ways of handling cutting on all of them have reduced doubling to almost none through the table facet, and the hair like side pipes we used to look for with a loupe are also mostly gone as any sort of I.D. feature. I am a long time estate jewelry guy selling at open air antique shows, mostly into colored stones and art deco/georgian stuff. Diamonds for me are kind of an afterthought or accent stone in a larger genre of design. But it's getting tough , I have all the Presidium dual testers and a ton of eye experience and try to stay away from larger 2Ct. + diamonds as being too risky.
I'm wanting to buy a Single round diamond with some smaller diamonds on the side. All Laboratory. HPHT or CVD ? G quality and above. Hopefully you can help this novice out. Thx very much Nevada USA Engagement ring 💍
Hi I was wondering if you have used the Gemtrue Veritas Diamond CVD/HPHT and moissanite tester ,as I'm wanting to buy it but I did buy the Gemtrue multi Experior from them and it was terrible testing moissanite as diamond and then mix readings again and diamonds as moissanites was not accurate at all ?
Hi! I have not tried this instrument, but have contacted the company in the past to try and understand the technology better - to which I wasn't given details for the way it works, and therefore I ca't really predict its limitations or accuracy. It has not been tested as part of there ASSURE Testing Program, so there is no independent data regarding accuracy for this equipment either (that I'm aware of). Be nice and specific regarding the type of pieces you mainly work with and what you are trying to assess and maybe I can recommend something for you :)
@@TheGemAcademy hi thanks for the fast reply,and yes it's strange that there is no data or reviews on the tester ,I like how it's compact and voice activated and that it has nature diamond,lab grown diamonds and moissanite. but yes if you can recommend a tester that does all three like the Veritas that is accurate that would be helpful or if you ever hear that the Veritas does work without false readings I would love to know 🙂👍 keep posting your videos they are great and love watching them 😊
@@oakleymills4847 Hmmm...no. I know none that can identify diamond and moissanite that do not have limitations! These often test incorrectly so you often have to do more tests anyway. A bigger budget may get you closer to what you need (however please bear in mind that all screeners only identify most natural diamonds and refer everything else - so all stones are not identified per se) A great option for a screener (that does moissanite too) is Sherlock Holmes Detector or Dr Watson (same technology, different sizes) This tells you when a diamond is definitely natural and refers stones that are laboratory-grown diamond and all simulants along with some natural diamonds.... so further observations and tests are required to identify these stones BUT this is the same for all screeners - even the Veritas. Plus this a machine can test lots of stones at once. Another machine would be the DiamondSure. This is more expensive and can only test one stone at a time - but does the task of identifying natural diamonds and moissanites, and referring all laboratory-grown diamonds (along with a small percentage of natural diamonds) for further testing. There is no one machine that does it all every time :) I hope this is helpful!
Hi, I have the Veritas Diamond tester. It only reads loose diamond/ CVD/ HPHT lab grown. All the so-called treated HPHT (processed) read as Moissanite. It reads only D color to I color diamonds.
I've bought several diamonds from a small family coin and jewelry store. They sell used jewelry and they're very honest and reputable. My only concern is how can they tell if the diamonds are lab grown or natural? They use a Diamond tester but I'm not sure which kind. They are confident they are selling natural diamonds. What is the percentage of lab grown diamonds now that have flooded the market?
Without speaking with them myself, I do not know. Maybe they have trustworthy wholesalers who have the equipment necessary to verify the stones. Maybe they have the necessary equipment themselves. If the stones you have purchased have a diamond report, this is 3rd party verification of what they are. However, these do not typically come with small stones. Best way to find out how they know is to ask them and explore these questions and answers. If you want to verify what they are saying for yourself, you could send the item for valuation (which is an excellent routine to do anyway to make sure you're correctly insured). As for percentage, its hard to know as everyday the percentage is changing. However, sales of laboratory-grown diamonds jewellery took up 10% of the 'diamond' jewellery sales by the end of last year. :)
@@mikes5411 I haven't tried it! Though I can't see why it shouldn't work perfectly well. Whatever tester you use - read the instructions so that you use it correctly and know how to clean it aaaaaaand don't forget that it's just for colourless stones aaaaaaaand don't forget that some synthetic moissanites test asdiamonds and some HPHT laboratory-grown diamonds test as moissanite so you need to verify these by eye too!! 🤗
I have different testers with me. The easiest way way to differentiate between diamond/synthetic diamond and Moissanite is the specific gravity test. Buy the kit. It costs around $100. from the company Mineralabs. Testers do not provide the accurate result. A 6.8 carat HPHT treated diamond read as 2.417 RI on Presidium Refractive Index Meter II and the same stone read as 3.22 SG - which indicates as Moissanite. Diamond Specific Gravity is 3:52.
Great stuff Julia. Learned something today- electrical conductivity in Syn Moissanite
Thank you so much, Ronnie. It's so good to hear from you! I miss you and want to visit again! :)
you are great!
That's so wonderful to hear! Thank you so much :)
Great channel
You know I kinda prefer synthetic Moissanites now
Oh yeah? What do you love about them?
@@TheGemAcademy when I look at it side by side a diamond...it seems brighter? Also the price 😶

I want to send you a picture of my diamond
@@diamondmeteoriteandotherro8507 Feel free! I get a lot of that, so only special things please :)
Use a refractometer, that works.
I'm wanting to buy a Single round diamond with some smaller diamonds on the side. All Laboratory.
HPHT or CVD ?
G quality and above.
Hopefully you can help this novice out.

Hi there What is the best moissanite tester in your opinion thank you Happy Early New year Keep on pumping great content!
Hey! I'm a big fan of the GemTrue multi-tester. Great price and a great reliable unit 🤗 Thank you so much for your compliment! Happy new year to you!
@@TheGemAcademy Thanks for the speedy comment back! What are your thoughts on the gemoro ultratester 3+??
