Celtic Greenish Blue Sapphire Ring 0.73 Ct., 18K White Gold

This ring from The Natural Sapphire Company features a transparent 0.73 carat trillion shape greenish blue sapphire, with precise dimensions of 5.52 x 5.68 x 3.42 mm. The trillion cut produces lively faceting and a modern triangular silhouette, highlighting the stone's intense color saturation and excellent polish. Clarity is graded as very very slightly included when evaluated at eye level, which means the sapphire presents as clean to the naked eye while retaining natural internal characteristics that confirm its identity and origin. This sapphire was responsibly sourced from Montana, and has undergone a standard heat treatment to enhance color and stability, a widely accepted and stable enhancement among informed buyers. The gem is set in a refined 14K white gold mounting that complements the cool greenish blue hue, and the design lifts the stone to allow light through the pavilion while securing it in a classic three prong setting that balances display and protection.

When considering daily wear, sapphire is among the most durable gem materials available, with a Mohs hardness rating of 9, second only to diamond. Compared to commonly used gemstones such as topaz and quartz, sapphire is significantly more resistant to surface scratches, which makes it an excellent choice for an everyday ring. Corundum, the mineral species of sapphire, also exhibits good toughness and lacks perfect cleavage, reducing the risk of splitting under impact relative to gems with prominent cleavage. The heat treatment applied to this Montana sapphire is stable and does not compromise durability, and the excellent polish helps resist abrasion. The 14K white gold setting provides a strong and malleable bezel for prongs, offering reliable protection for the girdle and culet during routine activities. For longevity, we recommend periodic inspection of prongs and cleaning with warm soapy water and a soft brush, avoid exposure to harsh chemicals and heavy manual work, and consider removal for contact sports. Taken together, the combination of a well cut, intensely colored Montana sapphire, secure 14K white gold mounting, and sensible care results in a piece that is both beautiful and well suited to daily wear, offering enduring value to the educated buyer.
