Product Description

"I just wanted to let you know that we recently purchased a 1.5 carat Asha round and took it to the LA Jewelry Mart to find a setting. 

Three certified gemologists did not know it was a simulant, and even when I told one of them he wanted me to prove it!"

(and in opposite of Moissanite's recent price hike) we have introduced an additional 25% price reduction
We are able to offer this due to manufacturing efficiencies gained by our increased volume of rounds, and by our no longer offering the lifetime limited warranty.  
Customers who purchased before May 24, 2005 are still covered by the original Asha lifetime warranty.   
Purchases from 5/24/05 and forward still have the 40 day return policy with no lifetime warranty (but lower purchase price).


  • Learn more about Hearts and Arrows (H&A) cuts - 

Heart and Arrows, Ideal cut, and standard round brilliant all have the same number of facets (57).  

The difference lies in the angles, proportions, and symmetry of the facets.  

These differences result in widely differing brilliance (light return), with H&A offering the best light return in exchange 
for significantly more weight lost during cutting, and substantially more cutting precision required.  Learn more here.

  1. LOVE my Asha center stone!

    By Unknown on March 15th, 2013

    If you are looking for something in the flawless category then look no further. I had the Asha set in a semi-eternity band with F melee's and they match perfectly! I wish I had known about Asha earlier. Since my discovery, I have been sharing it with all my friends!

  2. If you're worried about Asha, don't be!

    By Unknown on December 1st, 2012

    Finally got my 6.5 mm H-color H&A round Asha set in my engagement ring, my fiance proposed, and obviously I said yes!

    I love my ring, so so much.

    I was lucky enough to have a friend who had an ACC Asha set in her engagement ring, so I knew (kind of) what I was getting into. Clearly the cuts are different however. But I am so happy with my ring/Asha! The color is wonderful and it had so much depth. The jeweler set a white topaz in the ring (they were not pleased that I wanted an Asha) but the Asha outshines the "real" stone by a mile!

    For a long time I was worried that my Asha would look fake or that it wouldn't be comparable to a diamond. For ethical reasons I did not want a diamond but no one enjoys being judged by strangers. The ring looks beautiful and the size is lovely and suitable for our lifestyle and location.

  3. Absolutely Stunning!!

    By Elizabeth on October 10th, 2012

    I received my ring today and it has exceeded my expectations! My 3.5 carat H&A Asha in the Timeless Regal Reproduction setting in platinum is absolutely beautiful! There is no way anyone would ever know that this is not a diamond. I am beyond pleased with the final product. I was actually speechless when I opened the box. Pictures coming soon!

  4. Best CZ--beats out Diamond Nexus!!!

    By Mandi on April 12th, 2012

    I bought a Diamond Nexus and an Asha just to compare--both 7.5mm. The DN looks good, but the Asha looks amazing and much more real! The Asha sparkles, where the DN shines back a whole lot of white which makes it look fake. I'm very impressed with the cut of the Asha!! It just sparkles! My only complaint is that they don't offer a warranty or that they don't set stones. I ordered a loose stone to have put in a setting. I'm hoping a local jeweler can do it well.

    [ note from BTD : we do set stones, we offer a number of options for jewelry items for all the stones we offer ]

  5. Sparkle is out of this world!

    By Unknown on April 4th, 2012

    ive had two diamond rings before i actually decided to buy my asha stone.THE BEST DECISION IVE MADE. when i received it, i was in shock of how beautiful and how much it sparkles! its insane! after my asha i will never go back to a diamond. in love!

  • Beautiful! But but be mindful of wear and tear.

    By Unknown on 23rd Dec 2017

    I have the 6.5 mm Hearts and Arrows round in my engagement ring. I have been wearing it daily for almost 5 years now. I will say first of all that it is a beautiful product. My grandmother, who owns a lot of fine jewelry, commented that it was the most beautiful diamond she'd ever seen. :)

    However, I am probably looking to replace the stone in the next couple of years. I've worn it constantly and have been hard on it--admittedly probably too hard. I have some chips at some of the facets of the stone, and a scratch across the top. I have not made any attempts to be very careful of the stone, either, though. I imagine if I'd removed it while doing projects around my house and so forth, it most likely would have held up better.

    It was a great value, though, and it looks indistinguishable from a diamond. I would recommend it and would buy it again. I'd just be a little more careful next time.

  • Very good product - but out of stock all the time

    By GIA Gemologist on 2nd Nov 2015

    Need 9.5mm, 10mm
    Out of stock for 9mm all the time!
    If it is not "out of stock", I can give a 5 stars.
    As a Gemologist, I think it is one of the best diamond simulant that mankind have ever made. It can not fool a gemologist, but it can fool thousands of other people.

  • 1 year ring-versary

    By Francesca on 30th Jul 2015

    I have been holding out on a review in order to really test the stone. (Keep in mind I do work hands on everyday)
    THIS RING IS AWESOME! I work 5-6 days a week mostly with my hands and haven't seen a single scratch or dulling in the stone. The only thing I could see as a problem is if you don't have a solitaire, as i have noticed if I don't clean it often it will seem dull. Cleaning a solitaire takes me fifteen seconds, so it does not bother me at all.
    I deal with about 300+ people a day, and an guaranteed at least three to five compliments. Most asking how recent I was proposed to because it's still so sparkly!
    This ring is amazing! Not to mention ethical!

  • Beautiful, but seeing wear and tear...

    By AScratchICantItch on 9th Jul 2014

    I have a 2ct Asha round set in the Tiffany reproduction ring. It was holding up well, but now, at the 15 month mark, there is a scratch across the table, and a small chip at the edge. Of course, nobody can see it unless they are closely inspecting the stone...but I know it is there.

    My ring goes through normal wear and tear. I have a desk job. I don't do much hands on stuff with the exception of carrying groceries and laundry baskets. Not exactly going rock climbing with my ring on, you know?

    The advertisement is correct in that the aesthetic quantities of the stone are fabulous, but keep in mind that it is not indestructible. Even real diamonds can chip and scratch.

    Unfortunately, the return policy is 40 days which isn't enough time to assess durability.

  • Fooled the Jeweler!

    By Emily on 6th Mar 2014

    For my birthday a few years ago, my father gave me an heirloom ring. It's a gorgeous intricately made art deco solitaire ring, made of 18K white gold, from the 1930's. A true work of art and craftsmanship.

    I've kept it tucked away for a few years, thinking someday I would have a real stone put in the ring. I recently began shopping around for a diamond, only to be shellshocked by the pricetag associated with a 7mm H&A round brilliant cut diamond.

    When given to me, it had a 'dummy stone' (a pink plastic stone that had seen better days) and while I wanted to put a diamond in the setting, I can't justify the $10K+ expense.

    Upon doing some research, I landed on the Asha. It was the perfect way to do justice to my heirloom setting without breaking the bank.

    I took the Asha and my setting to a local upscale/well-known jeweler to inquire about setting the stone. I never revealed it was a sim, simply referring to it as a "stone" for the sake of gauging his reaction.

    He was enthralled by the stone--looking at it with his loupe, going on about how clear it was, admiring the brilliance and lack of flaws. He then got up to take a closer look in another area (perhaps a diamond tester?) and came back and asked if it was a "CZ." I explained it was an Asha, a very high quality simulant diamond.

    He said he was very impressed by the stone--and remarked of the quality of the Asha compared to other CZs he has seen. He even mentioned he was thrown because most "CZ's" are marked as such, which the Asha is not.

    I returned not long after to pick up my ring and it looks amazing---the Asha sparkles in that heirloom setting like a diamond. Best of all, it's my little secret that it isn't, in fact, a diamond. Fooling even a seasoned jeweler was enough to make me feel confident in my purchase.

    Overall, I had a wonderful buying experience and will be back again for another Asha!
