Tell me more...

This is a dainty and beautiful Art Deco ring featuring a small synthetic, blue sapphire flanked by diamonds. This ring is small in size - a UK J.5 - and would be suited as a pinky ring.

Sapphire has been synthesized by man since the 1800s but the process became streamlined and the stones very popular in the early 1900s. It is not at all unusual to find antique jewellery featuring synthetic sapphire - they were very sought after at the time. 

In terms of chemical composition, this stone is identical to a sapphire that has been dug from the Earth. The main difference is this one was grown in weeks rather than over millions of years. Synthetic sapphires also tend to be very clear, with inclusions typically being gas bubbles and curved striations. 

The diamonds in this ring are natural, Earth mined stones and the ring is in a lovely condition for its age. This Art Deco piece would make a fabulous addition to your jewellery box. It's supplied in our recycled kraft ring box with our tailored gemstone care card. UK delivery is fast and free via Royal Mail.
