1.6ct Blue Montana Sapphire, Round cut
1.63ct Montana Sapphire, Missouri River Valley Deposit, Heated
7.1 x 4.0 mm, Cut in the USA by Dan O’Neil
A light and bright Blue Montana Sapphire with a slight hint of green, precision cut in the USA. Excellent round cut, with a small culet facet that will make setting low easy if so desired. There are some small internal inclusions under the pavilion, but they are difficult to see without magnification.
