Carbon In Diamond Nexus Simulants

What is the percentage of carbon in the DNL simulant? They won't tell me this and I'm a little iffy about it. Is there 85% or more carbon in them? - Heidi, New Brunswick

Hi Heidi,

Diamond Nexus, like many diamond simulant companies including those which create the moissanite simulant, will not reveal the exact amounts of ingredients in their simulant or the processes which are used to create them because it is ‘proprietary’ information – in other words, it’s their secret formula and they don’t want it to get out!

However, Nexus does provide a list of ingredients which are used to create Diamond Nexus simulants:

Carbon (C)
Sulfur (S)
Iron (Fe)
Calcium (Ca)
Cobalt (Co)
Nickel (Ni)
Yttrium (Y)
Zirconium (Zr)
Gadolinium (Gd)
Hafnium (Hf)

If you are concerned about the carbon content because you want to compare the Nexus simulant with a cubic zirconia perhaps this information will help (you can find out more about Diamond Nexus Labs too on EWR's page here):

A Nexus diamond is not a cubic zirconia simulant – it is its own type of diamond simulant which is quite different from cubic zirconia. A few diamond simulant manufactures produce a harder cubic zirconia simulant by applying a durable coat over the simulant, but this is not the type of simulant that Nexus laboratories create.

To compare the properties of a Nexus diamond to real diamonds, synthetic diamonds, cubic zirconia and moissanite, take a look at the table on the Man-Made Diamonds page.

While a Nexus simulant is one of the most realistic diamond simulants on the market, and one of the hardest in terms of durability, a Nexus diamond is still not a real diamond. But in terms of hardness, a diamond is a 10.0 on the Moh's Hardness Scale while a Nexus diamond measures 9.10 on this scale. To compare this hardness to other types of gemstones, sapphires and rubies are a 9.0 on the Moh's hardness scale and aquamarine is around 7.5 to 8. So, compared to most natural gemstones a Nexus simulant offers a higher level of scratch resistance.

If you are looking for a man-made diamond that is composed mostly of carbon, you may want to search for Synthetic Laboratory Created Diamonds.

Synthetic laboratory created diamonds have the exact same physical and chemical properties as a real diamond, but of course they cost much more than a diamond simulant. In fact, white synthetic diamonds cost just as much - and sometimes more - than their natural counterparts. But, fancy colored synthetic diamonds can offer a substantial amount of savings over natural fancies.

It you are hesitant about trying out Diamond Nexus, the 30 Day Money-Back Guarantee that comes with DN purchases might help. If you order a Nexus ring and you are not happy with it, you can always return it for a full refund within 30 days.

Nexus diamond simulants and synthetic gemstones (they also produce a line of synthetic topaz, ruby, emerald and sapphire gemstones which have the exact same physical and chemical properties as real gemstones) also come with a triple lifetime performance warranty and a lifetime gemstone loss guarantee. As an added bonus, Nexus is one of the only simulant diamond producers I have found that have a strong commitment towards environmentally friendly practices which include using eco-friendly sourced gold.

An alternative to a diamond simulant or synthetic is to choose a ring made with a smaller, but less expensive, real diamond. Or select a composite diamond ring style crafted with multiple smaller diamonds clustered together - this style is much more affordable because smaller carat diamonds are utilized instead of one larger carat diamond. An excellent resource for composite diamond ring styles, and smaller diamond wedding ring sets available for very affordable prices is Zales. Zales also has a long standing $50 discount on orders over $300 with an email sign-up.

But if you want a traditional engagement ring style showcasing a larger carat stone, DN is definitely an ideal option for an affordable ring in this style.

I hope this info helps – and if you do purchase a Nexus diamond we would love to receive a review on your purchase!

Best of luck with finding your perfect engagement ring style. :)
