Exquisite 1970s Vintage Brooch: A Symphony of Over 19 Carats of Fancy Colour Diamonds

Allow us to guide you through the captivating charm of this striking jewel. At first sight, its design unmistakably aligns with the 1970s ethos. However, contrary to the era's norm of predominantly colourless diamonds with perhaps a singular fancy coloured accent, this piece is a vibrant ensemble of fancy diamonds.

Such a harmonious fusion of staying true to the era's fashion, whilst innovatively selecting coloured diamonds, speaks volumes about artistic flair and sophistication. It's not merely a design choice; it's a bold statement of style and individuality.

The jewel's colour palette is strikingly similar to the fresh collections of Victoire de Castellane for Dior. Yet, within this piece, one can discern the underlying muse for today's modern elegance.

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 representatives for 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 been irradiated 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 clarity grades 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.
