Hand-selected for global demand, stability, quality, and value. The Defined Value Diamonds in a DVD disc are specifically selected to be the types and sizes used in engagement rings around the world, representing over 50% of all global diamond sales. Populations are growing globally and more people get engaged each year. This has made the type of diamonds used for engagement always in demand, unlike ultra large diamonds, or those used in fashion jewelry. Therefore, Defined Value Diamonds (DVDs) are likely to show consistent stable growth and be easily salable and liquid globally.
All DVDs start with GIA certification, the leading source of knowledge and the global standard for diamond grading. In the 1950’s GIA established the standards and definitions used around the world to grade diamonds to this day. While other laboratories may use GIA terminology, they are not the GIA, and they do not necessarily use GIA standards. That is why whenever you see a multi-million-dollar diamond, it always has a GIA grading certificate — just like all Defined Value Diamonds (DVDs) do, regardless of size. At Van Zwam, we ensure that each Defined Value Diamond (DVD) is of defined quality standards for accurate value determination. To do this, every DVD starts with GIA certification, and has the GIA Triple Excellent cut grade rating.
Van Zwam goes further than GIA. Before any diamond can become a DVD we inspect it to our own higher standard of quality than GIA. Additionally, we check for features and attributes that GIA may not note, but that we find relevant such as the nature of imperfections, color tone, and overall impression. Our standard for cut, clarity, and color are on the upper end of the GIA tolerance spectrum. We eliminate any diamond that does not meet our higher standard. That is what we mean by unassailable. These are some of the DVD features that allow us to offer you our exclusive Resale Promise.
