Circa 1840's/50's, an antique Victorian Turquoise and Diamond 'Forget-me-not' ring typical of the time and likely once given and cherished as a love token. In 18ct yellow Gold with gorgeous variegated Turquoise cabochons around a tiny rose-cut Diamond spark imitating the well known flower with romantic connotations. Very pretty and you might notice that the Turquoises (which can discolour with age and repeated touch) are greener to the shoulders. The locket back is intact and empty. 

The ring size unfortunately can't be altered; it measures an 'L' or '5.75' as is.
