The Boulder Antique Engagement Ring. Lovingly embedded in the center of the antique platinum filigree is a 2 carat, velvety, rich royal blue sapphire having enormous luster.

The elongated shield shape has tremendous finger coverage and is punctuated with millegrain, scrolling and wheat sheaf engravings, typical of the Belle Epoque era. This estate jewelry treasure, Circa early 1900s is an heirloom that is highly coveted by collectors.


Royalty often wore sapphires for dual purposes. Not only did the gemstone reputedly attract wealth, it also purportedly protected the wearer from envy and infidelity. Traditionally, people attributed to this gem the power to bring harmony between lovers as well as peace between adversaries. In addition, sapphires were said to put one at ease in social engagements and banish fraud.
