1.53 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

If you are searching for a gemstone that resolves the tension between everyday durability and rare, personal beauty, this sapphire answers that need with confidence. This is a transparent bi color sapphire weighing 1.53 carats, shaped in an elegant emerald cut with dimensions 7.39 x 5.99 x 3.84 mm, offering a refined rectangular silhouette that sits comfortably in a variety of settings. The color presents an intriguing duality, shifting between deep ocean blue and fresh green tones, with an intense color intensity that reads as rich and alive under natural light. Clarity is graded as very very slightly included when evaluated at eye level, which means the stone looks clean to the naked eye while retaining natural character when studied closely, and the excellent polish enhances sparkle and depth across the stepped facets. Origin is Ceylon Sri Lanka, a source long prized for its vibrant and characterful sapphires, and the stone has been heat treated, a standard enhancement that intensifies color and stabilizes tone, making this gem both beautiful and reliable for daily wear.

Durability matters when you choose a stone for a lifetime piece, and sapphires stand near the top of the hardness scale. On the Mohs scale of mineral hardness, sapphires register at 9, second only to diamond at 10, which makes them substantially harder and more scratch resistant than many other common gem materials. For comparison, topaz is around 8, quartz is 7, and many softer gem materials fall below that, so a sapphire is an ideal choice for an engagement ring or a frequently worn heirloom. The emerald cut contributes to durability as well, because the step facets and reduced crown profile help protect the stone from knocks, and the clean clarity and excellent polish reduce the likelihood of stress points from inclusions. Heat treatment is a stable enhancement when performed correctly, and in this Ceylon example it improves color intensity without compromising structural integrity. For those who value both beauty and practical longevity, the Mohs 9 hardness of this sapphire ensures it will maintain surface luster and resist daily wear, while proper care such as avoiding ultrasonics with significant inclusions and cleaning with warm soapy water will preserve its finish for decades.
