1.4ct Trillion Montana Sapphire
7.1 x 3.8mm, Cut in the USA by Samantha Rosenberg
An excellent Unheated Blue Missouri River Sapphire, with occasional hints of green and sometimes purple! Very light and well-distributed silk, not visible to the naked eye but enough to give a soft brilliance 🙂 Expertly cut by one of our USA lapidaries in a classic step-cut trillion, with cut corners for easy setting. This All-American Sapphire is from a dumptruck load of mine-run gravel we sourced at one of the small mines along the Missouri River in the 2018 mining season.
