1.67 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exquisite 1.67 carat oval blue sapphire measures 7.26 x 5.90 x 4.65 mm, and its mixed brilliant cut is engineered to maximize scintillation while preserving the rich, intense Ceylon blue that collectors seek. The geometric faceting pattern blends a well proportioned crown with a precisely faceted pavilion, creating repeated light pathways that capture, reflect, and return light toward the eye for exceptional brilliance. Unlike shallow or poorly aligned cuts that leak light and mute color, this sapphire’s faceting concentrates flashes of white sparkle against a deep cornflower to royal blue body tone, producing lively contrast and a sense of depth that changes beautifully as the stone moves. With a clarity grading of very very slightly included at eye level and an excellent polish, the stone presents clean, crisp facet junctions and an open visual field that enhances both sparkle and the perception of size. The fact that this sapphire is untreated, no enhancement, elevates its rarity and desirability, offering a pure, natural color and crystal structure that remain stable and timeless.

When comparing this gem to other options on the market, The Natural Sapphire Company’s offering stands out for cut precision, natural origin, and honest grading. Many sapphires available today have been heat treated or given surface enhancements to deepen color, or they are cut primarily to yield carat weight at the expense of light performance, resulting in duller appearance under real world lighting. This Ceylon sapphire marries an intense natural hue with a tailored mixed brilliant faceting scheme that outperforms typical step cuts and elongated ovals by delivering both lively sparkle and saturated color. For those seeking value, the combination of an intact, natural origin, superior polish, and a cut designed to unleash maximum light return provides a long term investment in beauty and marketability. Set in a thoughtfully designed mounting, this 1.67 carat oval will sit with elegant presence on the finger, offering a wearable size that reads larger than many stones of similar weight due to the optimized spread and reflective architecture. Choosing this sapphire from The Natural Sapphire Company means choosing a stone that is visually superior, ethically sourced, and technically crafted to show its color and brilliance to best effect.
