Mint tourmaline and diamond ring

A gorgeous (and quite rare nowadays) square mint tourmaline with two square diamonds on either side. Set in white gold, it would make an ideal engagement ring.

The mint tourmaline is 2.5mm diameter and is 1.02ct. It has two 0.20ct diamonds on either side. The ring size is O1/2 at the moment but it can be made to any size. The collet is 7.3mm x 14mm and 5.4mm high. The band is 2.2mm wide. It weighs 7.1g.
