1.68 Ct. Greenish Blue Sapphire from Madagascar

This transparent, emerald cut greenish blue sapphire weighs 1.68 carats, and measures 7.55 x 5.27 x 4.14 millimeters, presenting a refined step cut that emphasizes clarity and color. The stone is graded as slightly included, evaluated at eye level, and displays a medium intense color saturation that balances depth and liveliness without appearing overly dark. The polish is excellent, producing sharp facet junctions and a clean, reflective table. This sapphire is untreated, with no enhancement, and is sourced from Madagascar, providing a natural profile that is fully stable and unaltered. The emerald cut profile and the gem proportions create a pleasing visual spread, and the transparency allows light to travel through the stone with clarity, supporting its overall presence in a finished piece.

From a durability perspective this sapphire is an excellent choice for daily wear, due to the inherent physical properties of corundum. With a Mohs hardness of 9 this gem is highly resistant to scratching under ordinary wear conditions, second only to diamond in hardness. Corundum exhibits no true cleavage, contributing to good toughness and a reduced tendency to cleave or split under impact, and the emerald cut with its step facets and large table distributes force across broader surfaces which can be advantageous in everyday settings. The excellent polish further reduces microabrasion by presenting a smooth surface that resists dulling. For optimal long term performance we recommend secure settings such as well executed prongs or a protective bezel depending on the jewelry type, regular inspection of the mount for loosened settings, and routine cleaning with warm soapy water and a soft brush. Avoiding hard knocks and exposure to harsh chemicals will preserve the stone and setting. The Natural Sapphire Company provides full details on origin and grading with each stone, and this Madagascar sapphire combines natural, untreated character with the structural attributes that make it well suited to being worn and enjoyed every day.
