The stone is secured in a platinum rubover setting which sits within an octagonal shaped cluster set with ten old mine cut diamonds, the two either side of the sapphire being both slightly larger and sitting slightly higher than the remaining diamonds. Decorative detailing in the gallery leads to a slim white gold shank. A timelessly beautiful Deco stunner.
