PINK DIAMONDS Lot of three round brilliant natural pink and purple pink diamonds of 0.27 ct, 0.10 ct and 0.09 ct. Clarity I1 - I2. Cut very good to excellent. ALGT report dated 25 October 2024 nr. 31621480. Dimensions : 4.18 - 4.21 x 2.50 mm. 3.01 - 3.05 x 1.79 mm. 2.97 - 3.02 x 1.73 mm. Not all diamonds are white. Some take on a natural colour, in particular through a minute change in their internal structure. Among the rarest diamonds in the world, there are three highly sought-after colours. Red is the rarest, with only a few diamonds known to exist in the world. Blue is also a colour that is rarely found because an element of carbon is replaced by boron. Next comes pink. It ranges from pale to crimson pink, its most intense shade, and is most often found in the Argyle mine in Australia, which closed in 2020. Pink diamonds are becoming increasingly rare, and you'll find not one, but three diamonds in this lot.
