1.59 Ct. Blue Sapphire from Madagascar

This transparent 1.59 carat oval blue sapphire, measuring 7.49 x 6.41 x 4.21 mm, is a rare combination of proportions, color and finish that sets it apart from many market offerings. The vivid color intensity is immediate and alive, a deep, saturated blue that keeps its presence without descending into the overly dark tone that can make some sapphires appear lifeless. Compared with commercial stones that favor size over tone, or trade rough that is heavily included and cloudy, this sapphire stands out for its balance. The clarity grade is slightly included evaluated at eye level, which means the stone retains excellent visual purity to the naked eye while still offering the character and natural origin that many collectors and connoisseurs prize. The mixed brilliant cut and excellent polish maximize light return and scintillation, offering the brilliant play that shoppers often find missing in mass market sapphires. From the first glance this gemstone reads as a finished jewel, not just rough material, and it carries the provenance of Madagascar which is increasingly sought after by buyers who want traceable origin and modern supply narratives. At The Natural Sapphire Company we present this stone as a thoughtfully selected option for those who want genuine presence, not just a checklist of specifications.

When you compare this 1.59 carat Madagascar sapphire to alternatives, several practical advantages become clear. Untreated stones have their own appeal, but market untreated examples with vivid saturation and eye clean appearance are far rarer and command premiums that put them beyond many budgets. Heat treatment is widely accepted in the industry, it is stable and permanent, and it enhances the inherent beauty of the sapphire without compromising durability or long term value. Many mass produced sapphires are overheated, poorly cut, or surface treated to hide flaws, and their visual performance quickly betrays those shortcuts. In contrast this sapphire’s mixed brilliant cut is engineered to combine the best of step and brilliant faceting, producing both strong color saturation and lively sparkle. The dimensions 7.49 x 6.41 x 4.21 mm are ideal for settings that demand presence without excess weight, making the stone versatile for rings, pendants, or bespoke pieces. The excellent polish is not a small detail, it means the surface finish catches light cleanly, resists minor abrasion, and elevates the overall look of the jewelry. For buyers comparing stones across listings, this gem performs like a higher tier offering because of the careful balance of color depth, clarity at eye level, expert cutting, and finish.

Owning this sapphire is an investment in beauty and craftsmanship because it combines natural rarity with the kind of human skill that turns rough material into enduring jewelry. Sapphires from Madagascar have become recognized for their strong, vivid blues and responsible supply chains, and this example benefits from that reputation. Unlike synthetic alternatives which can mimic color but lack natural origin, or low grade stones that need heavy filling or dyeing, this gem maintains authenticity while providing reliable wearability. The 1.59 carat weight is large enough to make a statement while remaining practical for daily wear, and the oval shape offers both elegance and optical performance that many round stones cannot match at comparable sizes. Investment value in colored gemstones is influenced by color, clarity, cut, and provenance, and this sapphire scores well across all those metrics. At The Natural Sapphire Company we select and present stones so buyers can see beyond just price per carat, understanding that a well cut, vividly colored, and properly finished sapphire will hold aesthetic and market value over time. Choosing this gemstone means choosing a piece that will age gracefully in style, that can be reset or repurposed as trends change, and that offers a tangible connection to the craft of gem cutting and the geology of Madagascar. For those seeking superior quality and long term satisfaction, this sapphire is a smart and beautiful choice.
