Presented here, an antique tiny Victorian era ring made in 18K rose gold (no visible hallmarks, so therefore it has been professionally acid-tested) and decorated with three (3) natural diamonds, measuring 3X2mm approx, each. The natural diamonds are three-facet antique rose-cut and they are ornated-bezel set (see pictures, please). 
Because of its small size, I would assume it is a baby ring, suitable also for the pinky (3  3/4 US size). 
Victorian people primarily wore them to symbolize love, friendship, and fidelity, although nowadays three-stone-rings could simbolize past-present-future. 
This Victorian era tiny beauty comes in a new darkblue color jewellery box with black color lining (see pics, please).
 
Please refer to the pictures, they speak by themselves.
 
MEASURES: the ring measures 7mm high, 6mm wide
 
US RING SIZE:  3 3/4, this is a tiny ring  suitable for children or for the pinky. 

WEIGHT: 0.94gr

ESTIMATED AGE: circa 1880
 
GENERAL CONDITION: very good general condition (please, refer to the pictures).
