Why should we buy brilliant moissanite forever?
Would you like to sell diamonds, diamond jewelery or jewelery set with stones, but you are not sure whether these are real diamonds and precious stones? We can give you certainty here, because we know that jewelry is often a gift or comes from an estate. And admittedly it is not easy for the layman today to distinguish between diamonds, zirconia and moissanites. Therefore, we would like to inform you about the differences in advance, as in our shops, as this plays a significant role in the sale of diamonds. Diamonds or brilliants and their properties are well known, so we would like to introduce you to the two “stones” that are also used in jewelry processing and that can often deceive the layperson.
Due to its hardness of 8–8.5 on the Mohs scale and an advanced production process, [the zirconia] developed into a high quality, inexpensive gem stone and is in demand in the jewelry industry today. A one-carat zirconia costs less than a thousandth of what you have to pay for a good quality diamond of the same size (only around 1 euro compared to around 8,000 euros - as of the end of 2017).
As gemstones, these can either be stabilized with yttrium oxide (Y-KZP) or with calcium oxide (CSZ). Calcium-stabilized zirconia can suffer from chemical burns when it comes into contact with boric acid, which is used, for example, to protect diamonds and other precious stones during work on fire during jewelry production. Since it is not possible to determine which oxide was used to stabilize the stone without extensive investigations, there is a risk of damage to the stone, especially when repairs to alleged diamond jewelery are actually KSZ.

This price difference, the artificial production and the comparatively low value make the zirconia a non-tradable stone in our profession, which is why we usually refrain from buying it.
A stone called moissanite has been on the rise in the jewelry industry for about 20 years.
Moissanite was first detected in 1904 by Henri Moissan in a mineral sample from the Canyon Diablo meteorite found near Barringer Crater. Its composition was first examined in 1892 by François Ernest Mallard and in 1893 by Georges Friedel; They recognized that it contained a particularly hard material that was inert to hydrochloric acid, and initially took this to be diamond. In 1904 Moissan was able to examine a large amount of the meteorite and recognized from the typical hexagonal crystals that the meteorite contains silicon carbide. The new mineral was named moissanite after its discoverer.
The artificial production of silicon carbide was first achieved in 1891 by Edward Goodrich Acheson (patented February 1893); moissanite in gem quality was first made in 1997.
Even if the moissanite can only be identified as such by a suitable analysis method, even for experts, it is not a commodity for us when buying diamonds. We are only interested in diamonds or brilliant cut diamonds. Nevertheless, you will receive final security in our company within the scope of a desired diamond sale.
Send us your diamonds or diamond jewelery with a commissioned transport service or use the opportunity to have us make you a direct offer. Only if you are satisfied will the purchase be made and you will immediately receive cash for your diamonds. With the correct valuation and a well-founded assessment of the condition of your diamonds, you have the guarantee that you can rely on a serious offer that is convincing in terms of payment.
