- GIA Grad + Founder and Front Man of F&B Michael walks us through a breakdown of Ruby gemstones. He is able to answer frequently asked questions about the gemstone that is sometimes referred to as "Pigeon Blood" rubies. If you're into red gemstones then you're in for a treat. Enjoy!
Be sure to tune-in the upcoming weeks for more in-depth educational "Geminars" where Michael will dive deeper into specific types of colored gemstones.
Enjoy!

Thanks for taking the time to show us this elaborate explanation.
Much appreciated.
Your lab ruby also has a deeper pavilion which adds weight.
I've gotten nice flame fusion synthetic rubies very inexpensively including some gigantic ones, all a very rich red. I put a 30mm long checkerboard cushion in a ring for some outrageous bling.
Excellent 👍👍👍👍👍👍
Great information--thank you!
Good guide
Thank you so much.
Very helpful, thanks
Thanks for your great videos and for the wealth of information they contain.
Would love to see these gemstones under uv light, and if you can tell the diffrence between real and lab created by using uv light. Not for ruby only, but for blue spinel and sapphire as well.
Thanks for a very informative presentation! I am weighing the purchase of a ruby necklace from Jaipur, India where the stones are described as oil color enhanced. Is this a heat treatment same or similar to the process you described? I understand this treatment is also used for emeralds. Heard elsewhere that emeralds are also formed from corundum. I think you mentioned emeralds briefly in passing. Just subscribed!
You should have also put a 20$ ruby (real lab made) from Ebay for comparison.
Those 20 dollar rubies are mighty nice. They are made using the flame fusion method which is much less expensive.
I am curious....is that 20 usd per carat? or 20 dollars for a "large" ruby ?
@@superfluity-of-naughtiness777 20 For a large Stone Bro 😂
I have one that looks like veins running through it. Is it a lab created?
What about rough rubies ? Can be cut ?
What year synthetic Ruby was created
Thank you.I have a red stone that I thought as ruby because the diamond selector 2 showed the hardness of10 moh scale.I went for GIA test.The GIA test answered that it was a lab created stone.I have more than 15 red and yellow and white polished stones.All stones are with the hardness of 10 moh scale by the test of my two diamond selector 2.Do those stone worth any US$?
no something is off with your diamond selector buy a better quality machine
You don't know what you're talking about! That crap tester of yours can not tell the hardness of stones, only if they are that kind of gem! And the only tester on the market that can tell you what kind of gem it is, is the
Gemoro Testerossa! And it can not tell you how hard it is or if it is a natural or lab !
How can you differentiate between the natural and lab created ruby from market life eBay? Most of the merchants don’t even know what is “natural vs lab created”.
@@Voduyendoidien : microscope! Lab created ruby/sapphire have half round striations because it forms in
a tube , natural Ruby has slightly V'd
striations.
@@rrfields65 sheesh, the man was simply honestly asking a question...you don't have to be so damn rude about it..
Ruby was in the old days used too describe ANY red stone and some of the mst famous ''rubies'' form the middle ages are Red spinels The wording of Pigeon bloods came form the mine owners whose mines had this colour ...Marketing is not new xxx
I want to see the natural and synthetic white and pink sapphire under the microscope at the same time, then I will know the difference between the two, thank you professor. ،F .
are synthetics dichroic
Yes.
The VERY BEST quality rubies are the LAB GROWN rubies made by something called the flux growth method, and sold almost exclusively by a company named Chatham Created Gemstones. Most MINED rubies set in "fine jewelry" (ie SOLID 14k or 18k GOLD ), except for the tiniest "melee" OR the MOST EXPENSIVE solitaires look pretty darn ugly. Walk into a Kay or Zales jewelry store, and ask to see a solitaire ruby, and you will almost inevitably be presented with something that looks like a "Red Hot" candy or a very purplish red stone that looks very dark and sleepy. Most people will be very surprised because these look nothing like the rubies seen in movie depictions, or books showing high quality ruby jewelry (which I can guarantee, Kay or Zales does NOT stock.) This is because clear, vividly red (i.e. "Pigeon Blood") rubies are incredibly rare. Far more rare than diamonds of equal size. A nearly flawless, one carat, pigeon blood ruby, sourced from Burma (where the very finest rubies in the world come from) can cost $10,000-30,000. These stones are among the rarest on planet earth. If you want to own a stone that is, in every way possible, superior to this Burma ruby, you need only look for a store that features Chatham rubies. These synthetic gems are BY DEFINITION, required to be chemically, optically, and physically identical to a mined ruby. It's ONLY difference, will be the cost ($300 to $800 per carat) and the fact that it will look as good, or in most instances, far better than that $30,000 mined stone. It is VERY IMPORTANT to note that Chatham flux grown rubies are made with a rather exotic process that dissolves the chemicals that make up a ruby (alumina and chromium) in a platinum iridium "cooking pot" that has been filled with molten molybdenum and lithium solution called flux. The process takes about eight to twelve months to complete, and uses a tremendous amount of energy. Those platinum iridium cookers are necessary because those metals can withstand the heat of molten flux without melting through, and cost hundreds of thousands of dollars. There is however, a process that costs far, FAR less, and produces stones not terribly inferior to Chatham gems. This process, called flame fusion, simply drops powdered alumina doped with chromium through a very hot flame. As the powder falls through the flame, it melts, and lands on a spinning platform where it slowly builds up. The finished product is every bit as much a ruby as either the Chatham, or mined stone. However, because it takes about an hour to create, the cost of even a well cut stone of ten, twenty, or even fifty carats, is only around a hundred dollars. These stones do not have as developed a crystal structure as either the mined stone, or the Chatham lab gem. This results in a rather "fake look" when fashioned into cheaply and indifferently finished machine cut stones. Indeed, every class ring with a red stone is home to a flame fusion ruby. However, if handled carefully by an experienced and conscientious cutter, VERY fine appearing stones can be cut from flame fusion rough.
First comment bro
Did you paid that much for a lab made ruby?
Surprised why you didn't mention Rubies from Kashmir and Afghanistan and Pakistan?🤔🤔🤔
Great video, but the lab created 2 carrot ruby priced at $900-1000 is about 10-20x actual market prices with hydrothermal being the more expensive. It’s making me question the overall accuracy of this otherwise helpful and informative video.
The lab-created ruby in this video is almost certainly a Chatham Created Ruby, based on the price and cutting style. Chatham Created Gems are the best of the best, and are quite expensive. They use the flux method to grow their rubies, which is a solution process similar to hydrothermal. Flux/hydrothermal rubies take much longer to grow than melt processes like Czochralski (being the higher quality melt method) and flame fusion (the fastest and cheapest process available). Flame fusion rubies can be bought for a few dollars per carat. Flux rubies tend to be the most expensive, often even more than hydrothermal.
@@joshharris3040 I got a "lab created" ruby from Kohl's department store closeout...Do you think it would be a flame or flux or hydrothermal product...offering an "opinion" would be great!
Why is that lab created that expensive but the same size lab created at department stores and large retailers is very very cheap? Are they not really lab created? I’m confused now.
Modern Magus thank you, that is very helpful information.
Because they are selling you a red spinal gemstone , not a lab ruby!
@@rrfields65 what is more expensive a nice quality red spinel or a lab ruby? Your answer did not specify
@@superfluity-of-naughtiness777 : A Red Ruby ( Red Sapphire/Corundum ) is 3rd on the Mohs scale ⚖️ of hardness ( 9.0 ) . Red Spinal is about ( 5.9 Mohs scale ) and scratch es very easy and is a semi-precious gemstone. Natural Berma "pigeon blood" Rubies are more expensive than Diamonds!
@@rrfields65 Thanks for your timely reply! However i still want to know what is more valuable ( per carat)... a "LAB" created perfect ruby or a high quality earth mined red SPINEL ???
Lead glass filled Ruby is not Ruby. Even by the ftc's definition, it must be described as a composite gemstone.
A lot of useless talk, from which I did not learn repetition. It is necessary to shorten speech and teach a way to distinguish natural stone from artificial only ، F .
