Below listed are the easiest tips to identify moissanite from diamonds manually.

  1. Double Refraction: As we talked before, Diamonds never has double refraction property. Here game becomes simple, using magnification loupe to see through stone’s crown, you might find blurry edges (joints) which might cause due to double reflection property in moissanite. In the example image, we can see the refraction of facets into stone. Diamond never looks like this, Sometimes reflection into Moissanite is less compared to shown in the above image.
  2. Check Stone Weight: The weight of Moissanite is 15%-18% less compared to a diamond. Two stone (one moissanite and another diamond) with similar diameter varies in weight. For example, a round diamond with 6.5 mm weighs 1.00 carat, whereas moissanite with a 6.5 mm weight of 0.83 carats.
  3. Extreme Brightness & Fire: Moissanite has extreme brightness and fire compares to diamonds and cubic zirconia. If you find extraordinary flashes of color, it’s probably moissanite. Fire and brightness in moissanite are two times more than diamonds. Also, another diamond substitute named cubic zirconia has an intense fire.

Harsh’s Opinion – Why You Should Buy Diamond Over Moissanite

I’m not against buying moissanite. But here are my views, why you should buy diamonds. Being in the diamond industry I will surely promote diamond first. But, I will give reasons which make you think twice before buying moissanite for your life partner. If “budget” is the point that makes you choose moissanite over a diamond. Then let me tell you, there is a diamond for almost every price.

Natural Diamond Is More Than Just A Stone, Its A Feeling.

Diamonds are a symbol of love. We all know moissanite sparks more than a diamond, even it’s less than half of the price of diamonds. Then why not buying moissanite instead of a diamond? Well, almost every moissanite today we see are lab-created and not real (natural). So, how would you feel expressing your real feelings, love & caring with a lab-created stone that is just extra shiny? Natural diamond not just hold values, but it is a stone that takes billions of years and a lot of pressure with heat in formation. That’s what makes the natural diamond so special.

Diamonds As Investment

Believe it or not, Investing in some kind of diamond has the highest ROI comparing other investment options. Natural diamonds are rare, hence with the time goes value increases. But, before investing in diamonds, I would suggest taking expert advice. Because not every diamonds will give you good returns in the future. Diamonds are rare and “Investment Diamond” is extremely rare. So, investing your money in “Investment Diamonds” is more worth than putting your money in moissanite which has no/less resale value.

Easy Replace & Quick Cash

Diamond in a ring can easily be replaced with other diamond or even give you quick cash when need. Diamonds are widely accepted in any country. You can visit jewelry reseller and sell your old diamond ring with good money. Moissanite ring is generally less accepted and has no/less resale value.

  1. Agree with our article 100%. I have both good size real diamonds and Moissanites. It is possible to distinguish it by the naked eye. The brilliance and shine is simply different. If cost is a concern for the newly engaged, I recommend purchasing rose-cut diamonds which is much less, but still a real diamond.

  2. I dont personally like moissanites and am looking for a diamond but your comments about “Natural diamonds are girls best friend and the best way to express your real love.” are silly. Money cannot buy love and expensive does not mean REAL love. Moissanite can also mean real love. Its personal preference. Neither is better than the other.

    • Hi, I am glad to hear your views. Just like yours, I have shared my views here in the post.

      I didn’t mean hurting your or anyone’s felling here( if unintentionally I did so, apologies for that).
      Also, I never mention “buying expensive means, real love”.

      My opinion here is meant to say “If you are withdrawing your plan to buy a natural diamond just because of the price, there are diamonds available for almost every budget ( so for rose cuts or salt & pepper diamonds, they look cool and available at reasonable prices)

      Also, I believe buying moissanite or diamond is a completely personal choice, and I appreciate that.

      I hope you have a fantastic weekend Susan !!
