Natural labradorite gold plated solid sterling silver ring

This is a superb free-form cushion-cut natural labradorite gold plated solid sterling silver ring. I purchased it from the Osprey London store many years ago. The gemstone is exceptionally good and shows the iridescent property of labradorite which better known as labradorescence. I’ve had it double gold plated for more durability. Stamped 925 inside the ring shank. This ring is a size 6.0-6.25 and in excellent vintage condition.
