Not all synthetic saphire crystals are grown in the the same way. This seems to be a sloppy flame fusion product. Some other methods like Flux Grow or Czochralski wouldnt yield any bubbles or the curved stripes within the grown crystal structure but may manifest some other type of inclusions unique to the method. In any case a lab grown sapphire crystal boule is huge compared to the cut stone. So you can select the better parts of it to work with. Also thanks to your magnification we can easily see that this stone is cut very poorly. It's probably a training cut or something.
Can someone please explain to me why natural gemstones are preferable? If synthetic ones are more perfect, have fewer inclusions, nicer color, etc. then why do people scoff at them?
Rarity, really. There methods that can be used to synthesize gems with the appearance of naturally occurring defects, but as I understand they can still be identified with careful inspection. People scoff because when they hear synthetic they don't fully understand what it means. Thoughts of lead-glass filled rubies, or heck, glass itself, even plastic, come to mind. The only thing that over-rides that is either a connection to the cutting process [see below], or choosing synthetic for ethical reasons, in that workers were not exposed to hazardous, or just tedious underpaid conditions so they can own the net result. I cut gems for a hobby. [By the way, the cut on the stone in this video is horrendous.] I cut gunky natural pieces, and while they are not flawless, or have great color+clarity, they have 'personality'. they are not defined by perfect color and clarity, but known precisely for their defects, just like many of the most interesting people in our lives. I am also a materials scientist, and geeked out on Lord of the Rings, so the concept of making your own gem is pretty effing cool. I own synthetic ruby, and plan to cut it sometime soon. It will give me great practice for natural pieces, but beside that, people who know me personally will value it despite not having been delved of the deeps, because they know who cut the piece, and why. By extension, if I could put together my own verneil process and make my own flame fusion ruby or sapphire, it would still be synthetic, but it would be 'artisan' synthetic ;) I could at least call them home-made If you ever want to learn more about gem cutting, or stone shaping in general, look up your local "LAPIDARY" club. they may offer instruction in using faceting machines. It's all down hill from there!
@@Ogg13tube Yeah, that was a native cut stone - almost all such stones have atrocious cuts. They are all cut for maximum stone weight, with little regard to clarity, defect hiding or color maximization. I have re-cut hundreds of such stones to vastly improve them, but the process usually loses a large share of the weight. Often I am lucky to get 50% recovery of the starting weight.
@@buggsy5 Why do you lose so much weight after re-cutting the poorly cut stones? I would think you would lose less than cutting straight from a piece of rough, as the stones are essentially pre-formed (I suppose 50% IS better than straight-from-rough yield in most cases though). The exception would of course be excessively shallow stones where the only way to save it is to drastically reduce the length/width dimensions. A stone cut too steeply (a lot more rare in my experience) shouldn't need to sacrifice too much weight, right?
@@joshharris3040 My apologies for taking a year to answer - I ran across your question by accident. There are several reasons that great weight loss can occur when re-cutting native cut stones. 1) The stone is misshaped, sometimes greatly so. 2) The wrong orientation was chosen so the color is not as intense as it could be 3) The pavilion and crown are tilted in respect to each other 4) The choice of facet angles is wrong. 5) Many stones have too shallow a crown or pavilion, or both (you mentioned that problem). 6) The crown and pavilion facets are not lined up. Keep in mind that most of these cheap stones are cut using a jamb-peg system so all alignments and facet depths/angles are done by eye. My stones are all cut using a meet-point technique, so material loss is somewhat greater than if less care was taken with facet meets. But many of the stones are so bad that it is more profitable to just grind off about 30% of the pavilion and treat it as a piece of rough.
I just purchased a synthetic sapphire for $7. They state it is flame fusion. Its got great color and flawless. However due to how low the price was and how perfect it is, is it possible this is glass? I am new to lab created gems, so I am not sure.
@@ortegon18 This is 100% untrue sapphires will not turn red under UV light, they will do nothing under UV light, they do not fluoresce at all. You are thinking of ruby another type of corundum, it is the chromium that makes ruby red that glow under UV light which sapphires do not have any of.

@@nigelthornberry7513 The only difference between a "ruby" and a sapphire is the depth of the red coloration. In other words, a ruby is just a sapphire with denser and purer red than more common red sapphire.
Isn't this a much more complex subject than you are making it out to be? There are multiple types of crystal synthesis out there. wouldn't it have been better to show the common defects in each type? I mean this may work for this type, but you might see something different in another.
He dose show common defects ie the gas bubbles and curvature of them as well like 10 seconds into the video he says I see no inclusions which is a good indicator this is synthetic. It would be impossible to show all the defects of synthetics because they are constantly changing its better to know what natural and real stones habits are to better determine if something is natural or synthetic. I think maybe you missed that part.
I worked in a sapphire plant for apple. They were going to use it for the screens but changed their mind after wasting millions of dollars. My Kyocera phone has a sapphire screen and it's amazing. The sapphire was perfect and makes the best screens ever apple messed up not useing it.
Any scope of about 10x to 50x/60x with dark field capability would be sufficient. You can buy a basic one for a few hundred dollars (US), but it might not have a camera port.
I don't know why no one did not answer your question sooner because I was asking the same and yes it's a really sapphire it's just not a natural grown sapphire it's just as nice and just as strong

Thank you for your video . 👍
How much is a synthetic sapphire worth?
Please make a video on real emerald stone i want to see that.thanks
How do you get curvature in two completely different directions in a flame-fusion synthetic?
worth per ct?
Awesome. May I know how to differentiate the curved stiae and the polish line? i always get confused
marzk2ya@gmail.com
send me your email pls
Curved lines are inside the stone while polished Line Can be Seen with surface light.
We have same one like this and it’s beautiful 😍
you have all riht, this is a syntheti ruby of the mineral corundum, with lot of bubles.

Use UV light, if it turns red it's a sapphire.

there really arent that many different types, just flux, flame fusion, and pulled which is basically just flame fusion 2.0
Well, I really don't believe they actually managed to make such a perfect crystal with such an old technique. They must have had a lot of patience

what XD
please provide the details of the microscope u used here ?

thanks
Thank you
Thanks a lot
But are the hardness the same or not?
I don't know why no one did not answer your question sooner because I was asking the same and yes it's a really sapphire it's just not a natural grown sapphire it's just as nice and just as strong
And what exactly the refractive index of synthetic sapphire.... Is it same as natural like 1.76-1.78
Yes, the refractive index is identical.

Thanks for NOT telling me anything about the flame fusion process. Why didn't you title it "Identifying synthetic sapphire"?
Dislike!
I have 1.3kg stone the this video
They should be illegle.
Why should they be illegal?
