"The Amora Gem is simply amazing in real life!!! I will never purchase another diamond..."
"I am so happy with my decision to get an Amora Gem - a diamond just cannot compare."
"...it does have more fire and scintillation than diamonds!"
"The Amora is Amazing."
- A few examples of customer feedback on Amora Gem H&A
Amora® - More Fire, More Brilliance, More Passion™
Amora Gem is the world's most stunning gem. (Note - you are welcome to view a series of videos comparing Amora Eternity to the world's previous most stunning gem, H&A Diamond here).
Amora Gem surpasses diamond in the essential measures of permanent beauty - brilliance, toughness, fire, and luster.
Further, Amora Gem is also able to match the world's most valuable white diamonds in color and clarity, with up to D color, and Internally Flawless clarity.
The Amora Gem is over one million times rarer than diamond (based on the past 10 years of natural diamond production vs Amora Gem production).
Amora Gem is composed of 50% carbon and 50% silicon, and only grows in star-like conditions that would vaporize diamond.
The Amora Gem crystal naturally occurs around large stars as stardust, but was never available on Earth until now (thanks to seven figures and eight years of research and development).
Amora Gem is grown in a laboratory where the star-like conditions it naturally grows in have finally been replicated on Earth. Thus every Amora Gem is 100% conflict-free and environmentally friendly.
Amoras are each individually graded under the GIA diamond grading scale and priced according to their carat weight, color and clarity.
We do the initial cutting our Amora Gems with our own in-house built TIGER robot system. With <10 micron precision, it is the world's most advanced gem cutting robot. Our TIGER robot is now multi-patent-pending!
(In addition, our robotic cutting facility is now 100% green energy powered from a mixture of primarily wind, but also solar/low impact hydro).
The Eternity H&A thus delivers incredible H&A symmetry and precision including our synchronized 64 facet, vertical faceted girdle so you can enjoy the world's most stunning and most perfectly cut gem, Amora!
Below: a Sarin HD Analysis of a common, mediocre diamond, an H&A diamond and an Amora Gem proving the cutting precision of the Amora Gems. Sarin HD is the only 3D scanner approved by GIA for symmetry grading as it does a facet by facet analysis with extreme precision. (Explanation = "Dev" is "Deviations from perfect" where smaller is closer to perfection. 0.0 would be absolute perfection. You can see the march towards perfection from Diamond->H&A Diamond->Amora Gem).
Note that the 64 facet girdle is a time consuming endeavor - this is why it's only done on high end gems like the Amora Eternity H&A, and H&A mined diamonds.
Above: Amora Eternity H&A zoom photo of our 64 facet girdle - same as H&A Diamonds.
CZ, Moissanite, etc. all go the generic "polished" girdle which is quick and easy to do - just polish around the girdle and done. For Forever One Moissanite, the girdle is only 95% polished - the area they will laser engrave is left rough.
Above: Forever One Moissanite girdle photo - polished girdle only, no faceting. Amora Eternity H&A is the only diamond alternative with a 64 faceted girdle, same as H&A diamonds.
Note that the polished girdle (unfaceted) makes it quick and easy for anyone to simply look at a gem from the side and immediately tell if it's a low value CZ or Moissanite, or a high value H&A diamond or Amora gem. The girdle is extremely telling in that respect, which is why Amora Gem is unique in the diamond alternative market for perfecting every aspect of our Eternity H&A, including a high end 64 facet girdle.
Eternity H&A Cut design - Cut controls 98% of the brilliance:
Our new Eternity H&A Round is the result of using the world's most advanced gem modeling software (currently owned only by the GIA and BetterThanDiamond in the US), and then a month of deep computing simulations using the only stereoscopic modeling system in the world, along with ten years of real-world evaluation of thousands of H&A diamonds (credit to Jonathan Weingarten, AugustVintage.com).
Stereoscopic modeling mimics exactly how you see - which is in fact a slightly shifted left image (left eye), and a slightly shifted right image (right eye) with the final "picture" of a stone being the combination of these images in your brain. Thus, what looks good under standard monoscopic modeling is really only applicable for a cyclops, rather than dual vision humans. As a result, the Eternity H&A was developed and perfected as the ultimate in Fire and Brilliance for the Amora Gem based on stereoscopic human perception. The result is the most firey and brilliant Amora Gem in real life viewing!
The Eternity H&A is the successor to our previous Soaring Hearts & Ultra H&A cut. Note the difference in the Eternity H&A arrows, which are now an optimal medium thickness:
Amora Gem is both patent-pending, and patented!

What exactly is Amora Gem?
Amora Gem is the world's newest gem, a cousin to diamond, and the most brilliant member of the 200+ member silicon carbide family. While diamond is composed of 100% carbon, Amora Gem is 50% carbon and 50% silicon.
For the first time ever in human history, Amora is now available as a gem on our planet. While diamond has previously been the most desirable gem, the Amora surpasses diamond in every aspect of optical beauty and toughness.
You can read read more here regarding what is an Amora Gem?
Is it a naturally occuring crystal?
Yes. While Amora Gem for jewelry use on Earth is grown in a laboratory (and thus avoiding the issues related to mining), it is a naturally occuring crystal that has existed as stardust around large carbon-rich stars for eons, long before our planet was born (see Astronomy & Astrophysics journal, April 1988). The starlight you see in the night sky may very well have sparkled off Amora gem stardust.
Since Amora Gem only grows in conditions that would vaporize diamond — extremely high temperatures such as those around larger stars — it is not naturally found on the Earth like diamond is.
It is only now after eight-plus years of research and development that the star-like conditions required to grow the Amora Gem crystal have been achieved in a lab.
Thus, for the first time in 4.5 billion years since our Earth was formed, Amora Gem is finally available here on Earth to jewelry lovers around the world in very limited quantities.
When were the first Amoras shown and sold?
The first sales of Amora Gem started in July 2013, right here on our website since we are the official maker of this stunning gem. One of the very first Amora Gems was displayed at the Hungarian Natural History Museum as the newest/youngest crystal on our planet. The first larger Amora Gem now graces the finger of a former Miss America.
Why was Amora Gem crystal never available on Earth until now?
Due to the incredibly high temperatures Amora Gem requires for growth - literally star-like conditions, it has never been available as a gem crystal until now. Its lack of availability is perhaps one reason that diamond became the most prized gem on Earth.
The multi-patent-pending Amora H&A lab-grown gem is now available to consumers in select countries for the first time.

What does an Amora Gem Eternity H&A cost?
Amora Gems are sold by diamond equivalent carat weight with the price per carat determined by color and clarity.
Base pricing is currently $428.95/ct for F color, VS clarity for Amoras produced after Sept 4th, 2016.
A full detailed price chart showing the discounts and premiums based on color and clarity is available here.
Amora Gem Eternity H&A vs equivalent diamond pricing:
Amora Gem competes with diamond on the basis of its intrinsic properties and beauty — greater fire, greater brilliance, greater luster, greater toughness and 100% conflict-free and environmentally friendly. However, cost is a fifth C beyond Color, Clarity, Carat and Cut, which is certainly another bonus for the Amora Gem Eternity H&A.
Below is a price comparison of various natural H&A diamonds versus Amora Gems, taken from BlueNile.com on May 15, 2014. Note that H&A becomes extremely rare in natural diamonds over 3ct size, so Ideal cuts had to be used after that. You can see the distinct pricing advantage of the Amora Gem when you make exact apples to apples comparisons of color, clarity, carat size and cut.

Patented - Australia, 2016100041.
Eternity Hearts & Arrows™ :
Within a given crystal type, cutting controls 98% of the brilliance. Hearts and arrows cutting is the absolute premiere cut for natural diamond, but only 2% or less of natural diamonds are ever cut to this level of optical perfection. Because Amora has much greater brilliance and fire than diamond, the hearts and arrows parameters had to be completely revised and improved for the Amora Gem to account for its superior optics.
In an industry first, all Amora Eternity H&As are cut *exclusively* by robot. Robotic cutting enables super-human precision and incredible craftsmanship compared to hand cutting, ensuring that the Amora Eternity H&A has unparalleled precision and beauty.
Amora H&A gem compared to other gems:
In short, Amora gem is truly the ultimate gem, eclipsing diamond in every measure of optical beauty.

I received my Amora Gem months ago. I absolutely cannot tell you how happy I am with it. I have never seen anything like it. I took it to a jeweler, compared it to his real diamonds and honestly, there was no comparison!
He is remaking my ring and he asked if I would like to take the stone (Amora gem) with me until he is ready to set it. He said he didn't want me to worry about the safety of the stone!
He thought it was real and he looked at it under a loop!
By Unknown on July 9th, 2015
Hello, I just received my order a few hours ago. I've been reading about Amora Moissanite and Amora Gems recently and have been following a few forums to get extra opinions. I wasn't sure which one to choose, so I decided to get both and keep the one I like. Once I opened the envelopes and compared the stones, there was no question which was the winner. I love the Amora Gem! It is quite spectacular, and I was relieved to see the fire and brilliance it has (some pictures on the forums did not show the fire I was hoping for so I wasn't sure if the moissanite would be the better option). For this reason, I'd like to keep the Amora Gem and return the Amora Moissanite.
By LW on July 5th, 2015
While searching online for diamond substitutes that looked like real diamonds, I came across a blog that talked about a variety of CZ's, Asha, Moissanite, and Amora. I ordered a ring made of Russian CZ's from another site, but sent it back immediately because it looked "fake" the moment I opened the box. After reading all of the reviews and watching the videos comparing Amora to diamonds, Asha & Moissanite, I decided to order a 1.8 ct. equivalent round brilliant stone to set in a setting I'd fallen in love with at Shane Company. I chose a G colored stone because the stones in the setting were G-H and I wanted all the stones to match. When I checked what a G-colored, IF, round brilliant diamond would cost if I purchased it from Shane Company, the cost was $24k+! When my Amora stone arrived, I couldn't wait to place it in the ring setting - it was fabulous and looked exactly like a diamond. I had the stone set and I got the ring back yesterday. It's so incredibly beautiful, I can't stop looking at it. My husband is thrilled that I'm so happy with it and I feel very smart for having the look of a $30k ring for $3500! If you're worried the Amora can't possibly be as great as these reviews say, don't be. BTD has a generous return policy, but I can't imagine anyone would be disappointed with Amora.
By Unknown on June 29th, 2015
I have been a customer of BTD since 2005 when an online search for diamond simulants led me to your website. My first order was a v5 Asha, 1.25 carats set in the original Tiffany reproduction ring and I loved it! People actually thought I was wearing an actual Tiffany and several friends were so jealous!
Fast forward through several ring changes, style changes and stone changes including more Ashas (I tended to be hard on them), moissanite (I tried hard to find ones that didn't cast green or yellow), Mira and Amora moissanite. I was more than thrilled when I started reading about the Amora Gem and reading the weekly updates had me on an emotional roller coaster! Could I afford one? What was taking so long? Curse that stupid patent! So finally I was able to purchase one which was a 2.17 carat G/SI1 but ultimately decided to send it back because, to me, it still showed body color compared to my Asha.
I would follow posts on the message boards about people getting their Amora Gems and loving them and posting their beautiful photos, so after almost a year, I gave it another shot. This time I ordered from BTD a 2.15 carat F/IF Amora Gem and when it came I was prepared to be underwhelmed. Boy, was I in for a shock! The gem I received is nothing short of perfection! I have had it for about 5 days and have carried it around with me everywhere to check it out in different lighting compared to a loose Asha and a Forever Brilliant H&A moissanite. The Amora wins, hands down every time!
When I think about all Less has done for the jewelry community from his excellent customer service to sharing his love for the ecosystems and animal welfare...I mean, I can't find enough great things to say about this man! "Thank you" just doesn't seem to be enough. He finally created the stone of my dreams, and I know many others feel the same.
Sorry this is such a long message, but I really want others to know what he has done and to have the joy of experiencing the Amora Gem for themselves. I will never go back to diamonds again. I can't wait to have my gem set and wear it proudly on my finger and for anyone who mentions my beautiful "diamond", you can bet your sweet tomatoes that I will set them straight and inform them about Amora Gem.
By Unknown on June 13th, 2015
I really do love my ring. It is absolutely gorgeous! The Amora is stunning. The owner of the diamond exchange place where I took it said that not even a jeweller would be able to tell my stone is not a diamond unless he/she tests it. And not only that, but a D colour diamond! That means a lot to me, as even though I realize I purchased a gorgeous gem that rivals a diamond, I have no intention on admitting it is not a diamond!
My engagement is not until September so I have yet to wear the ring non-stop but for now I can't stop staring at it in different lights.
By Unknown on 10th Jun 2020
I received it last Thursday and it’s amazing! It’s gorgeous and even more beautiful in person! So over the top happy w my purchase! Thanks you!

Thanks for the amazing gem ! I love it !

We received the gem and I was soo impressed!
By Unknown on 18th Jun 2019
My Amora Gem ring finally arrived today and I can honestly say that all of the reviews are true! It looks exactly like a diamond, and the way that it reflects light is unbelievable! For anyone who’s thinking or skeptical about this ring, I was exactly like you. I did a lot of research, went on a lot of forums and saw pictures before I decided to take a leap of faith and I’m definitely very impressed. One thing to note, it does take at least 3-4 weeks before you will receive it, so be ready to have a lot of patience especially if you’re anxious to see it. It is well worth the wait! BTD has great customer service especially coming from Less, he’s usually quite responsive to any inquiries or concerns you have and will provide any assistance he can to resolve the issues!
By Unknown on 17th Apr 2019
I am very happy with my Amora Gem! It is as scintillating and gorgeous as I expected thank you!
