Thank you so much. Is beautiful. Probably by fusion flame.

Most likely, as stated in his similar listings.

The price is outrageous. Judging by the au domain, I'll assume it's in AUD, which should equal about 300 USD, and it's still outrageous for a 1ct lab ruby.

This is nearly 3ct, precision cut by a very skilled cutter: https://precisiongem.com/gemstorenew/gemstore.html?store-page=Ruby-Lab-Created-p709305410



Nearly 3 times the size, and still less expensive.

I think I just bought that one recently! Here are a couple pics. It's very sparkly, but it doesn't look like any natural ruby I've ever seen. In terms of natural stones, I would say it's a little bit more like an almadine or rhodalite garnet, one with absolutely zero brown. It sparkles a LOT but it doesn't seem to have flouro - I took it outside to see if it pops and it didn't seem like it did. I could be wrong though. The sparkle is absolutely insane and the precision cutting is beautiful. The color is a little dark and it feels very fairytale Ruby if that makes any sense - like the kind of deep red you would see it in an illustration or a movie.

Is a beautiful Ruby, in absence of seeing under sunlight I would say this is not what I'm looking for in terms of color.
Thank you to much

There are only a handful of companies producing lab grown gem material. I would suspect that most cutters are buying from the same sources. The differences you see are in the photos. The same gem photographed with different cameras can look different. Now factor in the type of light, and the RAW image processor when converting the image from RAW to a JPG. Also you need to consider any processing on the photo. Most photos need some processing to make them look for realistic. Take the images above by Indylady. The color balance is off. The white on the gem jar should be white, but it has a strong blue with green. This needs to be corrected and is very simple to do, even your iPhone Photos app and fix this.

All lab grown ruby will have very strong fluorescence, usually stronger than most natural ruby material.

As someone else in this thread pointed out, you could never tell the difference between a flame fusion ruby and a pulled Czochralski once the material is cut. It would take a well equipped lab to tell them apart.

Thank you for weighing in, Gene!

Here are two lab rubies I cut a few years ago. One is flame fusion, one is pulled Czochralski. Which is which? Cut to the same design.

I found a few nano sital that might be red-red, if you're interested. Or maybe not. I really can't tell from the pics:

Here's a red cubic zirconia that might be bright red. I guess you'd have to see in person to know for sure if anything is the shade you're looking for.

Is #1 flame fusion? Uninformed guess.

 

[Dr_Diesel]

@Jade2 Please be aware that some sellers will claim they are using Czochralski pulled material (because it fetches a higher price), but in fact sell you flame fusion material. Unless you plan to get a lab certificate for your lab-grown ruby (or have a microscope and know what to look for), you may never know the truth about what you actually purchased.

$300 for a traditionally cut 1ct lab ruby is truly an absurd price. I would be suspicious of any seller who is asking such a price. It sends up big red flags for me.

You can buy stones like the one you're showing for literally 8-10 baht per carat ($0.23-$0.29) in Bangkok's Chinatown, which is a big hub for lab-grown corundum.

The cost comes from the supply chain, cutting costs, etc. That stone probably cost no more than 200 baht ($5.77) to cut. A precision-cut stone, especially from a skilled US cutter, costs significantly more.

Caveat Emptor

Thank you so much, I imagine is too usual paying much more for these stones. I will keep searching.

Thank you so much

 

[seaurchin]

Thank you so much

You're quite welcome. They all look either pinkish or orange-ish on my screen but who knows, maybe one or more are red-red in real life. The only red-red "gem" I recall having was glass but I guess that wouldn't be very durable. I'm surprised a pure red shade is so hard to find because my guess is it would be wildly popular!

My experiences with various lab rubies was exactly the same.
Zero brown - dark red. Some with touch of purple. Some with the man made inclusions - some not.
Sparkly. Very.
Fluorescent under a torch - but not with that ‘natural ruby lively aspect’ under normal natural lighting.
Pictures were incredibly hard to take and get accurate results - as was pointed out upthread - to what the various lab rubies looked like in comparison to natural ones sitting next to them - to my eye.

I think it comes down to what specific ruby look one is wanting to duplicate with mm material. If it’s not the look you want - as much as someone else states it looks just ‘like a ruby’ - if it doesn’t scratch the particular itch you want, It doesn’t.

@Jade2 - imo it’s well worth bringing in multiples from different vendors/sources to find what your eye is looking for.

So it seem always there is something "unnatural" in lab grown Rubies's color.

I think it's the clarity. Most natural rubies don't have the clarity of the lab grown gems. Some have a little silk or slightly less transparent which gives them more of a glow and softer look.

Have you by chance one Ruby made by Jeff? I would want to see more "natural" photos of hes stones.
Thank you.

That's a Flame Fusion ruby. Every lab that grows these numbers them the same, and they are all pretty identical. Here's the numbers for red, going from pink to a dark ruby. Pink is really just a lighter tone red.
As I said before, the differences you see are difference in the photography and lighting.

 

[dk168]

Thank you. I asked Jeff for more photos but he didn't want.

That's normal, based on my previous experience with him.

He has already provided a video of his stone.

For the price he is charging, I understand why he is reluctant to put in the time and effort to take more photos, etc. etc...

I need to see a natural photo and a video made without edition to decide.... I understand Jeff's stones will be great, and I was thinking on buying him seriously, but not without seeing "real photos".
Thank you!

This is true, I believe is necessary to see a lot of them and comparing.

I can appreciate your need to see more real photos before purchasing.

However, I am trying to advise you to be realistic about your expectations when you request for additional photos/videos for a stone that has very low profit margin for the vendor that may not result in a sale.

[VividRed]

This is true, I believe is necessary to see a lot of them and comparing.

Synthetics have the same properties of natural stones. Specifically in corundum: pleochroism. That means that you will never find a pure red ruby, it will always have some pink or some purple. Or it will be very dark, in which case it will be red and brown.

I have 20+ synthetic rubies from multiple vendors. They all look very red, but not pure red. For pure RED get a spinel, but it will not be cheap. Most are pinkish red or orangy red.

Yes, for example, the stone I showed you firstly is great to me. I seem the photos I received from the seller as real and natural.
I'll wait to receive photos from other sellers or cutters that I like the same or more to compare, and if I don't receive them, I'll probably end up buying that first one. What bothers me is that it's a bit expensive.
Thank you so much.

Thank you so much for your advise. I'll search the spinel.
Could you also recommend me a Ruby vendor?
Thank you.
