As mentioned last week, the president of BTD has published the most recent news on our discussion board.  Here are a few highlights:

Soaring Hearts – First Soaring Hearts H&A ready for sale! After a lot of investment in R&D and new tooling and many months of effort and testing, we’ve now got our first 8mm Soaring Hearts finished.

Let’s start with the very first one and it’s grading report:

Amora Gem Soaring Hearts grading certificate

As it worked out, the first Soaring Hearts were actually certed on July 4th. Appropriate since Amoras are 100% cut in the USA!

Detailed highlights of the new Soaring Hearts:
1 – New Nano-metric polishing
2 – 64 facet vertical girdle – the same as done on H&A diamonds.
3 – TIGER micron-level precision cutting. We’ve improved the precision over the previous TIGER cut Ultras.

The grading lab did take a high-res (60x) photo so I could show the new nano-metric polish, so here’s a zoomed in look of the crown with the new polish:

60x zoom nanometric polish

As you can see, even at 60X there’s no polish lines.  For reference, the faint long white lines are the pavilion facets reflecting in.

The new 64 facet girdle is done the same way as H&A diamonds (vertical faceting). The girdle faceting is, relatively speaking, an extremely costly process – it takes up 1/3 of the cutting time to do 4% of the stone. In addition, you go from dealing with 57 facets to 57 + 64 = 121 facets!

This is why Moissanite, CZ, etc. all don’t bother to do the faceted girdles as it’s too costly. Instead it is simply polished smooth.

Soaring Hearts – upcoming production: We’ll be increasing production of the Soaring Hearts and should have 7mm – 9mm over the next two weeks, along with 6.5mm after that.
All of July and likely well beyond will be focused entirely on Soaring Hearts production as we have a very long waiting list to catch up on.

Next month we’ll definitely have more info such as pro photos, videos, etc. for the Soaring Hearts.
In the interim, have a great weekend and see you end of the month!

The full post with lots more news and details can be found on our discussion board, here!

Hi all,
I’d like to move our usual Friday update to next Friday (July 8th).

We’ve got the first Soaring Hearts (8mm) at the diamond grading lab – thus ideally after they finish the 3D laser inspection, etc. we can show the first offficial Soaring Hearts grading reports, along with our usual updates by waiting until next Friday.

Look forward to talking with you then!

Here are a few highlights from the most recent blog post from the president of BTD:


Another month and as usual lots of updates!

BTD’s 22nd Birthday on May 4th! I’m pleased to note that BTD will be celebrating it’s 22nd anniversary in a few days, and we’ll celebrate our 22nd with the best Amoras rolling out. Details below!

Amora Gem:

Soaring Hearts Ultra! In last month’s blog, I showed the Flying Hearts which was the winner of our optimization efforts. However, after another week of non-stop optimization and comparisons, we’ve moved to the new ‘Soaring Hearts’ design for our Ultra production going forward.

Here’s a computer video of the new Soaring Hearts design:

All future Ultras will be the Soaring Hearts cut.

We are planning to focus entirely on the Soaring Hearts Ultra, sizes 8mm – 6.5mm initially. We’ve yet to ever have enough 7.5mm and 6.5mm and so with our improved production, the first goal will be to much more robustly restock these. After that we’ll expand further into 6mm – 9mm Soaring Hearts and expand out from there.

Takaras will be discontinued: With all the excitement and momentum of the Amora Gem, it’s a bit disappointing to announce that we are officially cancelling the Takara lab diamonds.

Asha restock: The main sizes of Asha rounds have sold out again, and so we’ve got another run in process. Estimated restock time-frame is the end of May.


Quanza, our sponsored elephant, update! We’ve been getting monthly updates on one of our two sponsored elephants, Quanza. I’m happy to report that she’s doing extremely well and now has tusks! The orphanage always sends pretty small photos, but regardless it’s great to see her doing so well. Here’s the latest photo:



The full post with more news and TIGER updates can be found on our discussion board!

Friday updates posted! This month = our new, Flying Hearts Ultra H&A round, new Flanders H&A in progress, TIGER-2 and TIGER-3 in progress and more!  Below are a few highlights and photos but the full post with all the details is available on our discussion board.

Amora Gem:

TIGER robot updates! We’ve had our first month of testing and production with TIGER and the results have been exceptional.

How do I know if an Amora is TIGER cut? All Amoras are now TIGER cut so all new production going forward are Tigers. However, you can also tell by any of the following:

1 – Cert number – all certs 2005101 and higher are TIGER cut.

2 – The cert itself, under comments section – TIGER cut Amora’s are now marked accordingly in the comments section:

New Ultra – Flying Hearts Ultra! After substantial optimization runs, I’m pleased to show you our new Amora Ultra – the Flying Hearts Ultra!


And most importantly, here’s a computer generated video to show you the light play of the Flying Hearts Ultra:

And for comparison, identical computer video of our current Ultra:

New Amora “Pure Hearts” Oval! Next up – I’m thrilled to show your our new Pure Hearts Oval! This is the first “near H&A” oval to ever be developed, and we have a patent application in progress for it!
Let’s start with a computer photo-realistic video of our Pure Hearts Oval in spotlighting so you can see what it’s all about:

The “Pure Hearts” name was developed for this new cut because it had a hearts pattern from the first model. The arrows came later as part of the extensive computer modeling.

Most importantly the new Pure Hearts Oval completely eliminates any type of bow-tie! The result is exceptional brilliance and fire, and the overall look and feel of an H&A round – never before seen in an oval cut!

Two more TIGER’s (TIGER-2 and TIGER-3) in progress: Based on our inability to meet demand, we’ve decided to accelerate TIGER production and are thus building two TIGER’s now for the scheduled Sept completion. This will be important for us to try and ensure more Amora production for the big Holiday Season!

See the full post with all the details here!

This week’s Amora Gem restock is for our Amora Gem Ultra in 1-1.5ct weights.  Notifications have been sent to those who had requested them via our notification page!


TIGER cut, Synchronized and Faceted Girdle! This is a 1ct Ultra, with 64 individual facets, and 4 facets per crown girdle.

The latest news post has been added to the BTD discussion board.  The full post is on the Amora Gem Blog section of the discussion board, but here are a few highlights:

Amora Gem

TIGER robot complete, transported and installed… production starting next week! I’m very happy to announce that TIGER robot is now finished!
We’ve transported TIGER from Silicon Valley to our new WA cutting facility and it arrived safely yesterday morning.
Our robot engineers are flying out from Silicon Valley and will be working through the weekend to integrate TIGER and we expect to start TIGER production next week (March 1st – 4th)!

TIGER robot patent applications in progress: Note that during the R&D for TIGER, we developed many new key technologies to help us achieve our goal of 10 micron precision. We did review all of our breakthroughs with our patent attorney and will be filing 3 different patents for the TIGER robot.
Thus, our TIGER robot will soon be multi-patent-pending!

Amora Gem production schedule: With TIGER coming online next week, we will be focused on expanding the Ultra inventory first, from 4mm – 8mm sizes.

We’ll then start adding in Princess, OEC, Cushions, Asscher and AVC’s, Radiants, and yes – even Krupps.

BTD News:

X1 WhiteGold now available for our Timeless Rings: We are always trying to offer the very best available metals for our jewelry and thus we’re now making our Timeless rings available in X1 White Gold.
The one negative – white gold can trigger skin issues with some people. This is because of the nickel content. X1 has even higher nickel content, so it does not resolve that issue for those affected.
Palladium of course is both natively white and no allergy issues, but as many customers have noted, finding a jeweler who will work on palladium for resizing or other can be tricky,esp. outside of the US.
Thus, we’re pleased to start making X1 White gold available as a new option for customers around the world.

There’s more news and updates on the blog!


This week’s Amora Gem restock details:

  • Amora Gem Ultra H&A Cushions in 9.50mm-9.70mm sizes (4.25-4.5ct weight range).
  • Amora Gem Ultra in 7mm-9mm (1.25-3ct weight range).


Notification emails have been sent out to those who had signed up to be contacted when we restocked these options.
