0.69 Ct. Blue Sapphire from Madagascar

This transparent 0.69 carat emerald cut blue sapphire from Madagascar is a study in refined restraint and rare poise, a stone that speaks to collectors who prize purity of form and authenticity of origin. Measuring 6.28 by 3.55 by 2.79 mm, the gem is cut with the elongated facets and crisp step lines that only a masterful emerald cut can deliver, offering a disciplined play of light that favors depth and clarity over flash. The color presents as a medium intensity blue that is serene yet undeniably present, a tone that adapts beautifully to both warm and cool metals, and that maintains its character under varied lighting. Clarity has been graded as very very slightly included when evaluated at eye level, a level of transparency that allows the true nature of the sapphire to be admired without distraction, and the polish is excellent, resulting in clean facet junctions and a surface that reads as near mirror like. Importantly for discerning collectors, this stone is unheated and shows no enhancement, preserving the natural narrative of Madagascar provenance that many connoisseurs now seek.

For the collector who regards gemstones as both art and investment, this sapphire occupies a unique position. The elongated emerald cut is inherently architectural, offering a modernist silhouette that complements other high quality gems and elevates bespoke designs with understated authority. Placed as a refined solitaire or set within a precision three stone composition, the proportions of this gem create a focal point that is both elegant and quietly commanding. Owning this sapphire means possessing a natural rarity, a gem whose very lack of augmentation and whose Madagascan roots place it among a select class of stones that appreciate in desirability as clarity of origin becomes ever more prized. When you acquire this piece through The Natural Sapphire Company, you do so with the assurance that this gem has been sourced responsibly, examined by experienced gemologists, and presented in a state that preserves its original character. The combination of medium color intensity, high transparency, a superior polish, and the emerald cut profile makes it a textbook example of how restraint and quality combine to create lasting rarity.

This gem is an invitation to create something truly individualized, a rare opportunity to secure a natural blue sapphire that will sit proudly within a curated high end collection, and that will respond to the hand of a talented bench jeweler with predictable and rewarding results. Our team at The Natural Sapphire Company offers personalized guidance on settings that will best showcase the stone, from custom platinum mounts that emphasize its cool blue tone, to warmer yellow gold designs that bring out hidden nuances in the hue.
