Center diamond : 1.50 carat Old European Cut round brilliant, VS1

Accent diamonds total twenty

Eight full cut and twelve single cut, set in free-floating collets and bead-set, with mil-grain borders of tiny beading

Fine original decorative engraving extends down each side

The tiny spot of light visible here in center is the bottom facet, parallel to the table, called the culet

# 58 of the 58-facet 'round brilliant' cut, it is often so small in modern diamonds as to be invisible without magnification; in a well-cut "Old European Cut" round brilliant, it is typically visible--if only barely-- to the naked eye

Center diamond is held in two double prongs and two single prongs

Diamonds are bead set on each prong

8 French Cut Blue Sapphires, assumed to be flame fusion origin, calibre cut and set in chevron “V” formation on each shoulde

Finger size is 6; can be made larger or smaller
