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.

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. I love my Asha, I get distracted by the sparkle all the time :)

    By Rachel S. on March 27th, 2012

    I had been set on a real diamond since I was a little girl and practically coveted my mother's 1ct Marquis. So, when my boyfriend (now fiance) suggested something cheaper I balked. After having several long talks about how our money would be better spent on saving for a home and for our first child I decided to give a 1ct Asha H&A Round F/G color a try. I thought, sure, I'll get it for now and upgrade to a diamond later.

    We had it set by our local jeweler in a six prong platinum knife-edge engagement ring. It is the most gorgeous ring I have ever seen and every person I know has gushed over it! :) The only people that know it is not a diamond is us, my parents and our jeweler. Several of my work acquaintances keep telling me how lucky I am to have such a nice ring.

    Because I am so happy with it I seriously doubt I will substitute a diamond later as long as it holds up though the years. I plan on posting pics on the forum soon.

  2. BEAUTIFUL!!!!!!!!!

    By Unknown on March 15th, 2012

    My husband & I ordered a 6mm (.75 carat) F/G color H&A round Asha. It just took my breath away! Gorgeous in every lighting! I compared it side by side to a regular CZ & it by far passes it up 1000 times better! & The communication with the betterthandiamond crew was amazing & the shipping was fast! It shipped on a Monday & arrived today on WEdnesday!

  3. $200 or $5000 your pick.....

    By Daizy on January 2nd, 2012

    I'm a wholesaler of GIA certified diamonds as well as Asha stones, I personally wear Asha 6mm h/a round stud earrings f/g color in three prong martini baskets. I will never pay for natural diamond studs. I took my pair of studs, with a pair of GIA certed I color SI1 clarity ex/ex/ex studs, both boxed, to a few of my friends in the business. In one office were five ladies, shopping around for Christmas, plus my friend, and two other gents in the trade. I showed both pairs of studs & asked which they liked best. All but one person picked my studs, the one woman didn't like my martini settings so she picked the other pair. When I told them all that the pair they picked was $200 versus $5000 for the other pair, the room roared with laughter as all of them were in disbelief as to what they chosen, and how much they cost.

  4. Better than Diamond is absolutely right.

    By Alex on August 24th, 2011

    I spent months researching all the sims and ethics of buying a diamond vs sims before deciding on the Asha.

    I purchased a very realistic size for my budget, the .75 carat 6mm Hearts & Arrows Round. A co-worker has a ring with a certified .75 carat round in it from a well-known diamond dealer. Their stats were: VS2, Ideal Cut (Not Super Ideal), G color. Comparing them both side by side AND under magnification, the Asha trumped the real diamond hands down. Due to it's ideal cut, the light performance was absolutely amazing, and the hearts and arrows much more visible than the comparable diamond.

    The color and accuracy of the sparkles is not TOO bright like Moissanite, and most accurately resembles a perfectly cut diamond.

    If you think that most women have an instinct about these sorts of things... They don't. Every woman I've brought to look at my 'diamond' has absolutely been falling over how beautiful it is, and how 'lucky' my fiancée is.

    I splurged on an excellent setting from Tacori, which is much more important in my opinion, to having a beautiful ring overall.

    A note: Although I'm not telling anyone else, I'm not trying to fool my fiancée. She KNOWS it's a sim, and agreed it was in our best interests budget-wise to get this instead of a real diamond.

    Truth be told though, after seeing so many 'real' diamonds, the Asha is arguably the best looking and best cut stone I've ever seen, next to diamonds more than 20x the cost.

    If you're on the fence, just buy it and see!

  5. Everyone is blown away

    By Unknown on July 8th, 2011

    I'm now engaged (with a RB asha), and everyone is blown away by the stone...and I come from a family of jewelers! You guys are doing a great job.

  • 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!
