Post-Consumer Recycled & Antique Diamonds
Where they come from
These diamonds are repurposed from existing antique and vintage jewellery, and it’s likely their exact origin will be unknown. They have often been passed down through many generations and are a great sustainable diamond option, provided they come with a valuation certificate, as they don't contribute to the mining of new material.
Cut Description
There are various cuts that were used for antique and vintage diamonds. These are the predecessors of the brilliant cut diamond, which is the standard of cut used for all modern diamonds. Old cut styles, such as Single Cut, Old Mine Cut and Old European Cut diamonds are recognisable by their often irregular girdle, large facets and in many cases, a flat culet which can be seen through the top of the stone. They also tend to be deeper in proportion to a modern diamond, and they reflect light differently as they were designed to look their best by candlelight and other low light scenarios. They date back as far as the 1300s through to the early 20th century, the majority originating out of Europe.
Grading System
Post-consumer recycled and antique diamonds are graded following the standard system used for white diamonds. Due to their unique cutting styles, however, they do not come with a cut grade.
Certification
Due to the provenance of post-consumer recycled diamonds, most are sold uncertified, though exceptional stones can be accompanied by GIA certificates in rare situations.
Value
The value of these diamonds is determined by their size and quality, their cut style and whether or not they are certified. They are more affordable than a white diamond of equivalent size and quality.
