How Real Are Your Diamonds: Attributes Of A Genuine Diamond

Posted on

There are two types of diamonds: genuine diamonds and simulated ones. This then brings forth the question of what a diamond truly is.

The basic old-fashioned recipe for a diamond features carbon deposits found deep within the earth that are subjected to extreme heat and pressure. The new alternative recipe entails the same ingredients except, instead of forming it deep within the earth, these stones are created in labs. Origins aside, both are genuine diamonds with unique chemical, physical and optical properties unmatched in any other material.

The Other “Diamonds”

Anything that falls out of these attributes is simply diamond simulants. These imitation diamonds may generally mimic the appearance of this brilliant gem, but in actuality, they are made out of materials aside from pure carbon. Such materials include moissanite, cubic zirconia and even glass! Naturally, they’ll possess different attributes, including less durability (diamonds are the hardest material in the world) and different refractive index.

Unfortunately, discerning these diamond simulants from real diamonds have gotten harder and more challenging. On top of looking like actual scintillating diamonds, these simulants also use confusing names and terminologies to allude that they are made out of diamonds, such as Diamond Hybrid, Nexus Diamond and more. None of these is actual diamonds; they are all attempts to borrow the name to assume the look of a diamond.

Another term you’ll want to look out for is synthetic. Bear in mind that “synthetic” should not be conflated nor synonymous with “simulated”. A synthetic diamond has the exact same physical, chemical and optical properties as mined diamonds, lab grown diamonds being one of them. On the other hand, simulated diamonds do not possess the same attributes even if they are made to look similar to mined diamonds. No matter how they are manufactured or marketed, they are not diamonds.

How Do You Know Which Is Which?

At first glance, diamond imitations may get away with fooling any ole consumer, but those with sufficient diamond knowledge can tell a genuine diamond from an imitation. You’ll want to keep a lookout for the name and certification that specifically state that the diamond is a genuine, with no qualifying brand. Ensure that the diamond comes with a certificate from a recognised gem laboratory such as the International Gemological Institute (IGI).

At Star Carat, we pride ourselves on our stunning and quality lab grown diamonds. On top of being IGI-certified, our lab grown diamonds also land themselves in the TypeIIA diamonds category – a category reserved for the top 2% of global’s diamond production.

Lastly, be wary of any “diamond” of substantial carat weight that is not set in platinum, or white or yellow gold. Diamonds that are set in sterling silver are typically less than 0.5 carats. If they are any more than that, these “diamonds” are most likely not authentic. Be sure to take note when finding an engagement ring for your partner.

An At-Home Test To Authenticate Your Diamond

If you genuinely wish to find out if the stone you’ve bought is an actual diamond, the only pseudo-reliable method is to invest in a diamond tester. You can find them online, and whilst nominally priced, their accuracy is not infallible depending on the stone’s material.

Of course, if you’re in doubt, it’s always best to seek professional guidance.

Frequently Asked Questions

  • How can you differentiate a diamond from moissanite and cubic zirconia?

As mentioned prior, both moissanite and cubic zirconia possess different refractive indexes than diamonds, and this is reflected in the quality of scintillation, fire and brilliance. Moreover, they also have other qualities that are dissimilar to a diamond’s, such as durability.

That said, these characteristics aren’t something most people can detect easily at home. As such, you’ll want to consult a professional jeweller.

  • Can you differentiate a mined diamond from a lab grown one?

The simple answer: no. Both diamonds adhere to the 4C diamond grading and will come in the same degrees of cut, clarity and colour. Even a professional jeweller needs to use very specific equipment to tell the difference, and only those in gemological labs such as IGI have such equipment.

  • Does the scratch test help to determine whether a diamond is real?

Whilst effective, scratch tests should be avoided. Whilst it’s true that diamonds score a perfect 10 on the MOHs score, making them the hardest mineral on earth, these scratch tests can damage their polish or even chip them if struck at the right angle.

Again, it’s best to consult a professional for assistance.

  • Should my diamond float in water?

No diamonds should float in water. In actual fact, they should sink. With that said, this test should not be the barometer as there are other materials apart from diamonds that have a higher density than water, and thus would also sink.
