What is the quality of the diamonds you sell?

The diamonds we use for our jewelry are always of very high quality; VVS E or better. Here you will find an overview of the different purities of diamond. The very high quality is also better sharpened and therefore they shine more than commercial quality  (SI1 and V2 color G). We often get the question from people who wear MV jewelry why it sparkles more than other jewelry they own. That's because we make no concessions when it comes to quality. Both in our designs and in the diamonds and gemstones we use for our designs. 

Do you work with lab-grown diamonds?

We attach great importance to the beauty and exclusivity of natural diamonds. A natural diamond takes millions of years to form. A beautiful natural process. A lab-grown diamond, on the other hand, is created under pressure within half a day. 


Lab grown is often sold as a sustainable and ethical alternative.

Because we know exactly where we have to buy diamonds to meet that condition, we still opt for the natural product. Natural diamonds match the exclusivity of our designs. In addition, a lab-grown diamond loses its value immediately after it has been purchased. History shows that the value of natural diamonds is always increasing. This way your jewelery remains a valuable product, even for years and generations to come.
