Such a gorgeous labradorite marquise set in sterling and fine silver on a sterling silver open back oval cuff (so it should fit most people).The stone is a smooth cabochon, with a royal blue flash as the sun catches it. (Quite tricky to catch in a photo but I can pop a video on my facebook page).

The stone itself is approx 38x15mm and the cuff is sterling silver, 6mm wide by 2mm thick in a D profile (curved on the outer edge) and has been hallmarked. I've hammer textured the sterling silver cuff.
