7ct Emerald Fancy Deep Blue Diamond Ring by Moussaieff

A very impressive blue diamond ring by Moussaieff with an auction estimate of CHF 10,000,000 – CHF 14,000,000. As we have seen in the past diamonds of this quality and colour and clarity grade can achieve very high prices, I am going to put my neck on the line here and estimate this could go for at least CHF 17,000,000. I will be watching closely!

This piece is accompanied with reports by AGL, Gübelin & SSEF all 2019 which indicate the absence of any treatments. Auction estimate CHF 500,000 – CHF 700,000 it could achieve considerably more.

10.01ct D Colour Internally Flawless Emerald Cut Diamond Ring

As a fan of the emerald cut and other step cuts my heart skipped a beat when I spotted this rare beauty. A type IIa diamond is the purest type of diamond devoid of traces of nitrogen or boron. The diamond is set in a simple, elegant setting which could easily be changed if the new owner wanted to make this diamond into a show stopping piece. Auction estimate is CHF 700,000 – CHF 900,000 Which is about right I can see this stone selling for CHF 800,000

5. Sterlé Enamel and Diamond Harlequin Brooch

I think it is the facial expression which drew me to this brooch, a subtle smirk and whimsical flow. From the 1960’s with French Marks circular cut diamonds with vibrant green and blue enamel. Estimate CHF 10,000 – CHF 15,000 I predict it will go for at least CHF 16,000 one of 20 Sterlé brooches on offer, the perfect chance to add to your collection.

Pierre Sterlé is credited for being able to manipulate metal unlike anyone before him, he was seen as an innovator in the jewellery world and enjoyed the support of many large jewellery houses & socialites.
