If only I was in the market for new bling right now.
I love these warm rocks, and the prices aren’t bad either!

Maybe I could learn to like icy colors with this .99ct unicorn.

Not specifically related to Rhino, I know, but Yoram is asking for comments on CVD rough vs Mined rough!

If he receives positive comments regarding how people like the end, polished article, and how the original form is ultimately relatively irrelevant, hopefully he might be encouraged to cut some!!

Cool!!I ordered a lab grown emerald cut from Jonathan. He’s patiently working on setting cads with me. I’ll post it when I get it.![]()
I'm pleased to see that a PSer has commented to say the proprietary cuts in MMDs would be awesomeI'm glad you posted this @OoohShiny -- why aren't more people commenting favorably on Yoram's post!!

Well, they are exactly the same material as Mined diamonds (bar the 'grain' from their growth patterns, which requires a machine to detect) so no-one outside a lab or without a loupe (to read the inscription) would ever knowI’ve just discovered the existence of these and I am already planning projects. Does anyone have any photos to post of pieces they’ve created with the AV euros or cushions? I’m think of doing some 2ctw euro studs and possibly a piece for my mother. I just love the price and feel like no one will ever know since they’re so beautifully cut!
Tell that to the snotty sales woman at the jewelry store I went to last week. Made the mistake of telling her my ring was a lab grown diamond. She looked at it under the loupe and proclaimed she could tell it wasn't a natural diamond and she could never get a lab diamond. Queue massive eye roll from me. I just stopped shopping and walked out when she said that. Considered calling her manager after I got home to tell him she lost any business from me by not only being rude about my ring, but showing how little she knows about diamonds.Well, they are exactly the same material as Mined diamonds (bar the 'grain' from their growth patterns, which requires a machine to detect) so no-one outside a lab or without a loupe (to read the inscription) would ever know![]()
You should ask her exactly how she can tell a lab diamond apart from a Mined diamond (without looking at the inscription)Tell that to the snotty sales woman at the jewelry store I went to last week.

This is the sort of judgmental people that will probably never overcome the MMD 'stigma'!
lolI really wanted to tell her off but this is one of the stores in Philly that seems to have the most stock and I don't want to burn the bridge so I can keep going back and trying things on. I'll never buy from them, but it's really useful to be able to see how different sizes and styles look on my finger.
I don’t see the big deal? The salesperson could tell it was a MMD with a loupe and may never get one. She looked at it under the loupe and proclaimed she could tell it wasn't a natural diamond and she could never get a lab diamond.
You can't tell whether a diamond is natural or MM under a loupe. No one can.I don’t see the big deal? The salesperson could tell it was a MMD with a loupe and may never get one. Now, if she was rude that is a different story.
But that is a specific brand of MMD, which is marketed as having an internal marking added so it can be identified as MMD - they are not graded by a grading lab so do not have girdle etchings marking them out as MMDs.
Ah yes, I see where you are coming from now - perhaps the sales assistant managed to spot the logo within the diamond. (Sorry, I'm a bit slow today... lol)Agreed. In this case it is a Lightbox diamond that the salesperson viewed which can be identified with a loupe because of the Lightbox logo.
Welcome to the Dark Side!Some questions, will a colour grade "H", for example, in a CVD equal the same colour in a mine grown Diamond (GIA)? Does the same goes for clarity?
I recently stumbled upon the term "Stria" which is typical for CVD's (to my understanding), what more can be said about that?
Some clarification on my waffling!GIA only grades MMDs/Lab Grown Diamonds into 'Colourless' and 'Near Colourless' at this moment in time, which is not very helpful, so most grading reports are done by IGI, GCAL and others.
...
Clarity is much the same, in that both are graded under 10x magnification, but there are different inclusions to look out for.
GIA has issued reports for laboratory-grown diamonds for more than 10 years. In March 2019, following the guidelines from the FTC, the Institute announced it will change the name of the reports to GIA Laboratory-Grown Diamond Reports starting in July 2019.
To reduce the potential for confusion, GIA grading reports for laboratory-grown diamonds look significantly different from those for natural diamonds. In addition, the terms used to report color and clarity grades for laboratory-grown diamonds are different from those used for natural diamonds.
Instead of D-to-Z color grades, broader category terms (Colorless, Near-Colorless, Faint, Very Light and Light) are used.
Clarity grades, which are abbreviated on natural diamond reports (VVS1, SI2, etc.), use broader descriptive category terms (i.e., Very Very Slightly Included, Slightly Included) on the reports for laboratory-grown diamonds.

Are colour grades on these reports softer than GIA? Maybe... so IMVHO, aim for D-F colours and you should reduce risk of seeing tint (if that bothers you).
Some MMDs have a brown or pink undertone, though, so one should inspect any stones for that. (Again, it might not bother you, but buy in full awareness!) IIRC that is found more in HPHT stones, although the manufacturers seem to be treating stones (by heating, I think) to remove that tine.

The Stria/layering within CVD has been put forward as a cause of reduced clarity/fire/brilliance, but I've not yet seen any posted quantification of this.
Have a read of the links on this thread as it should help explain a few things better than I can, and includes discussions on Stria!
