A natural Ceylon sapphire with no evidence of heat treatment flanked by GIA certified half-moon diamonds. Under magnification one can clearly observe the intact rutile silk, a classic indication of scarce unheated corundum. Equally as impressive is the sheer size of this gem; at 25.04 carats this is truly a spectacle to behold. A circular surface reaching inclusion that may be pressure sensitive can be observed adjacent to one of the prongs. All three stones in this ring are certified as mentioned.
