1.59 Ct. Greenish Blue Sapphire from Madagascar

This 1.59 carat oval greenish blue sapphire from Madagascar is a standout gem, transparent and alive with vivid color intensity, measuring 7.49 x 6.41 x 4.21 mm. Cut in a mixed brilliant style, it balances scintillation and depth, delivering lively flash and strong face up color. Evaluated as slightly included at eye level, the clarity gives the stone natural character without compromising brilliance or durability, and the excellent polish ensures every facet returns light with crisp, lively sparkle. Heat treated, as is common with fine sapphires, this gem has a stabilized and intensified hue that reads as a rich greenish blue in daylight and a glowing teal under warmer light, a color that sets it apart from ordinary blues and creates a memorable presence in any jewelry design. At 1.59 carats the size is substantial enough to be noticed while remaining versatile for everyday wear, and the oval silhouette offers a flattering spread that appears larger than the numbers alone suggest.

When compared to other options on the market this sapphire offers a rare combination of attributes that make it superior in value and visual impact. Unlike many heavily included or poorly cut stones that lose life in a setting, this mixed brilliant cut maximizes light return without sacrificing the depth of color that collectors prize. Against lab grown alternatives, a natural Madagascar origin brings provenance and scarcity that speak to long term desirability, while treated but stable heat enhancement is a responsible and widely accepted method that improves beauty without undermining integrity, unlike diffusion or fracture filling which can limit future care and value. Compared with sapphires from other locales, Madagascar has emerged as a source of stones with lively, modern palettes that appeal to contemporary tastes, and this stone’s vivid greenish blue tone is both fashionable and timeless. The slightly included clarity grade is a practical advantage, often translating to better value than eye clean stones with comparable color and size, making this gem an astute choice for buyers who want maximum visual reward per carat. Our grading and description are precise and transparent, and The Natural Sapphire Company stands behind the gem with full disclosure about origin, treatment, and characteristics.

In a jewelry setting this sapphire’s vibrant color will arrest attention and uplift any design, from a minimalist solitaire to a diamond halo or a bespoke three stone ring. The oval shape elongates the finger, creating an elegant silhouette for rings, while the mixed brilliant facets catch spot lighting in a parade of tiny stars, making the gem vivid in candlelight or under office lighting. In pendants and earrings the greenish blue tone plays beautifully against warm metals such as yellow and rose gold, where the hue reads more verdant, and it also excels in white gold or platinum for a crisp, modern contrast that emphasizes blue depth. Pairing with diamonds or lighter sapphires will enhance perceived color saturation, and bezel or claw settings will both protect the gem and allow light to move through the pavilion for maximum life. Choosing this sapphire through The Natural Sapphire Company means you receive not only a striking, well cut natural stone, but also expert guidance on setting choices that will showcase its color and brilliance to best effect. For those seeking a gem that looks uniquely alive in every wardrobe and under every light, this Madagascar greenish blue sapphire is a compelling, high value option that stands apart from mass market alternatives.
