1.18 Ct. Bluish Grey Cabochon Sapphire from Montana

This 1.18 carat, round shaped bluish grey sapphire from The Natural Sapphire Company measures 5.88 x 5.84 x 3.12 mm, and is cut as a cabochon to showcase its semi translucent body and internal features. The cabochon form enhances the smooth satiny luster and allows the eye to appreciate the gem color and internal character without the light return considerations of a faceted stone. Color is evaluated as medium intense, a balanced saturation that offers visible blue grey tone while remaining versatile for a variety of settings. Clarity is graded slightly included at eye level, meaning that trained observation will reveal small internal features, but these do not overpower the gem and contribute to its natural personality. The polish is excellent, providing a clean, reflective surface that complements the cabochon domed shape. This sapphire has been heat treated, which is a widely accepted and stable enhancement in the trade used to improve color and clarity, and the stone is of Montana origin, a locality noted for its unique and collectible sapphire colors and responsible sourcing practices.

For the educated buyer, this stone offers a compelling balance of rarity, provenance, and wearable durability, corundum being a 9 on the Mohs scale ensures the sapphire is suitable for everyday jewelry when properly set. The medium intense bluish grey hue is distinctive, appealing to collectors and designers seeking a muted, sophisticated palette that pairs well with both white and warm metals. Slight inclusions are common in Montana sapphires and can act as a fingerprint of natural formation, adding character rather than diminishing value when evaluated in the correct context, especially in cabochons where transparency and internal texture are part of the aesthetic. Heat treatment should be disclosed, and at The Natural Sapphire Company we provide transparent information about enhancements and origin to support confident purchasing. The stone’s precise dimensions and excellent polish make it straightforward to design around, and settings that protect the girdle while showing the dome to advantage, such as bezel or shared bezel designs, will best showcase its color and surface shine. We can provide additional guidance on mounting and certification, ensuring that your acquisition is both a beautiful and informed investment.
