A dear friend of mine has ordered this bracelet by Spain-based Anil Arjandas. It’s a very intriguing piece: carbon for the bracelet body, with inset rose cut black and brown diamonds set in oxidized silver.

Arjandas launched his jewellery business in 2000, preferring to work with black gold, black and brown diamonds and leather, as well as relatively unconventional materials like the carbon in this piece.

It sells for €4,950 and can be ordered online or at one of three bricks and mortar stores.
