Synthetic Ruby made by the Flux process

- This is a synthetic Ruby made by the Flux process. It uses platinum crucibles and the platinum breaks off during the process and gets trapped within the gemstone. The platinum platelets are very irregular in shape and sometimes have very sharp edges and are commonly found in the triangular shape.
Hello Lucas:
Tom Chatham here...grower of flux rubies. One correction on your video: The platinum crystals do not "break off" the crucible walls....the platinum actually dissolves in our flux and then crystallizes on the growing rubies. In actuality, we are growing platinum, a basic element. Although we can grow platinum crystals, we cannot produce more than we start with, since platinum has no breakdown. These crystals are actually a pain for us and do nothing to help the growth of ruby...and sometimes gets in the way. However, I can state this: If a platinum crystal is found in a ruby, it is definitely lab grown...most likely a Chatham stone.
thanks,

Hey Tom, please advertise your gems via social media a bit more. If nothing, just make lab videos for youtube (things you are comfortable to show on camera)... I really like that lab gems are an ethical alternative. Iphones have good video making capabilities these days. All the best, loved your dad's story in an interview you gave.
Good analysis
Good job.
What happens if you use titanium instead of platinum?
Hi Lucas, thanks for another very informative video.
Which tool are you using -- I have dark field illumination but it does not have different lights and higher magnifications... Could you please tell me the Manufacturer name or send link -- where to buy it?? And where can I buy the Diffusor plate ?
Thank you.
what is the difference between Hydrothermal vs Pulled (rubies / emeralds) ? How is a pulled ruby different from a hydro rubies? Which is better, more resistant, better looking?
Hi great video as I am trying to understand how to identify real vs lab grown vs fake rubies and sapphires. I have a stone with inclusions that look like strands of fiberglass, not straight like all the silk pictures I’ve seen. I know that it’s hard to comment with such little information but curious your thoughts on what this could be. I tested with a diamond tester and it’s reading 9 on it.
can you please upload about natural growth lines video tell how they are in real and synthetic
Hi ! That is a great looking gem, I was wondering were could I find information on the production process? Thank you a lot !
+MinuteMenu I think you could find some on Wikipedia. I have found a number of sources through Google.
Hi Which method is the better way to grown sapphire? Flux grown or flame fusion or pulling?
Flux grown
Super
Can I use this process to make ruby for laser?
@Gadolini Rutherfordium Really? This is great. Thank you very much :)
@@o.429 you would only need to use the flux method if you are planning on counterfeiting Ruby's to sell for millions. As this method makes it neatly impossible to tell if its fake
think it is titanium or tungsten. not platinum
Why use platinum as a heat resistant material? The melting point of tungsten is twice that of platinum, and platinum is much more expensive, so why not use tungsten instead?
Tungsten is nicely flammable at the temperatures needed; the furnace would need to operate in inert atmosphere.
Tungsten is also a fairly reactive metal, oodles of the stuff will dissolve into the mix.
The last nail in the tungsten crucible coffin is its extremely brittle nature.
Doesn't bend, shatters like glass.
Greg Gallacci ahh I see now
Platinum is used for it resistance to chemical interaction. Tungsten would not work.
@@tomchatham8896 I assume iridium would address this, that is if you could get enough of it to make a crucible.
The flux material is highly reactive. Tungsten would not work. Must be a Nobel metal. Gold, Platinum, or iridium works.
Tungsten titanium
