A typically Edwardian antique ring, understated yet beautiful in its construction and gem choice. The ring has been made from solid 18ct yellow gold with a 'boat' shaped setting. In the setting sit 3 round sapphires, and 4 single cut diamonds. The central sapphire is an Earth mined stone and straight growth lines can clearly be seen with the loupe. The outer stones, which are slightly brighter blue, could possibly be synthetic sapphires - still sapphires in their own right, but grown in a lab rather than in the Earth. They were extremely popular from 1905 onwards.

All sapphires show minor abrasions to the facet edges as you would expect and have likely been heated to improve their colour. The single cut diamonds, though small, are bright and beautiful and are a welcome contrast to the deep blue sapphires. The shank on this ring is thick and solid and has many years of wear left. We can see evidence of a finesse mark or hallmark, but it has rubbed from wear. We have tested the gold to confirm purity of at least 18ct. This is a charming little Edwardian ring that is very flattering on the finger.
