EXCELLENT. This is a gorgeous antique Platinum Diamond engagement ring. In excellent condition throughout, this piece is sure to lead to an 'I do'. The Diamond is secure in her prong settings, and she has an ever so slight inclusion to one side which is visible beneath a jeweller's loupe. The inside of the band is fully hallmarked, and there is little wear to note.
