Cubism Unfolded: Sapphire Diamond Ring


A sophisticated bejeweled ring of platinum truly represents the tenets of Art Deco. A quartet of rectangular cut natural deep blue sapphires with an estimated total weight of 1.1 carats strikes a dramatic linear pose across the surface of a quadrangle of platinum accented with a border of mille grain work.

Surrounding the brilliant blue sapphires is a rectangular frame of eighteen (18) very fine old European cut diamonds of an approximate 1.08 carat total diamond weight, I-J color range and VS2-SI1 clarity range. In combination the diamonds and deep blue sapphires just come alive with an intensity which is simply dazzling to behold.

Date: Circa 1925.

Educational Note: Did you know that one clue to natural sapphires is that often you can see parallel and straight zones of color? That is very difficult to see with the naked eye. However, look closely at the sapphire on the right in our first photograph and you can find the lighter and darker stripes. While a challenge person, our macro photographs have highlighted the natural property. You may be able to see that natural phenomenon if you hold the ring up to the light and look very close as well. Voila, you have just identified the stone as a natural (non synthetic) gemstone - as are all the rest!
