Diamond five-stone ring, 19^th century. Five-stone rings with beautiful open-work scroll galleries are one of the classic styles of the Victorian era. This example, with its series of graduated, well-matched late 19^th century circular-cut diamonds totalling approximately 1.90 carats, is particularly spectacular. With rose and single-cut diamond accents, the effect is a continuous band of light across the finger – an excellent choice for an antique engagement ring that sits perfectly alongside a wedding band.
