For this spectacular jewel, we wish to take you by the hand and guide you through the most astonishing aspect of all of its wonder. From the first sight, we recognise that this jewel is designed according to the style idiom of the seventies. However for this vintage period, we would expect the use of colourless diamonds with exceptionally only one fancy coloured diamond as an extraaccent instead of an entire composition of fancy diamonds as we see here. The union between such respect for the fashion of the time and such an avantgardistic choice for exclusively incorporating coloured diamonds is a testimony of artistic genius and sophistication, but even more of courage. It takes confidence to craft this piece as well as to wear it. The colour palette in this brooch reminds us of the recent jewellery collections of Victoire de Castellane for Dior, except here we're gazing at what belongs to her source of inspiration, the origin from which other grandiosity stems.

Extra information on the quality of the diamonds and their gemmological reports: In general, we prefer to avoid taking gemstones out of a jewel to maximally preserve the authenticity of the piece. Usually, a quality estimation through preservation is regarding antique and vintage jewellery more valuable than exact information.However in this case with fancy coloured diamonds, there's even more value in exact information, so we've tried to keep a reasonable balance in our choice to test these diamonds by only taking out nine diamonds for certification as the representativesfor the entire lot. You can inspect the lab results from IGI (International Gemological Institute) in the section of photos, but here we'll highlight the most important aspects regarding fancy diamonds. Concerning their colour grades: All diamonds in this brooch are natural diamonds and their colour origins from an extra treatment. Since the 1950's, the fancy colours of diamonds have been created by heat treatment and/or irradiation. The diamonds on the market that have beenirradiated are not radio-active, so don't pose any danger. Besides that, not all colours of a diamond fall in the category of "fancy coloured". Only diamonds of which their colour is intens enough are permitted to be called "fancy". That is the case with all of the diamonds in this brooch. Concerning their clarity grades: Not only do these diamonds have a high colour grade, also their clarity is quite good, generally ranging between VS and VVS. This is a rare sight for diamonds that have been treated for their colour as this is usually done with diamonds in lower claritygrades to upgrade them through colour treatments. Therefore, one would expect low clarity grades for colour treated diamonds. These facts only make this brooch even more unique.
