This is so gorgeous. It is a deeply chased 14 KW gold ring with a corn flower blue 0.85 CT Montana Sapphire stone. It is in pristine condition and will soon be 100 years old.
The ring is size 7.5 and weighs 7.4 grams. It could be sized by your local jeweler if needed. Please look carefully at the inside of the ring, what care has been taken in its manufacture.
This ring is dated by the style of the chasing and the fact that Montana Sapphires first came to popularity in that era. A great ring for either gender.
