1.56 Ct. Greenish Blue Sapphire from Madagascar

One of the most compelling natural sapphires you will find is this transparent 1.56 carat round shape greenish blue sapphire from Madagascar, offered by The Natural Sapphire Company. At 6.88 x 6.97 x 4.51 mm, this gem sits in a perfect size range for a striking solitaire ring or a refined pendant, while still being versatile enough for halo and three stone designs. The color reads as a rich, greenish blue with intense color intensity, and because this sapphire is untreated, its hue is a direct expression of Madagascar geology rather than human alteration. Compared to many market alternatives that have been heat treated or filled to enhance color, this natural sapphire carries greater rarity and intrinsic value, and its no enhancement status means the color and clarity you see are genuine, consistent, and durable over time.

What truly sets this stone apart from more common and commercially cut sapphires is the mixed brilliant cut and the meticulous geometric faceting that has been applied. The mixed brilliant cut combines a brilliant style crown with a more controlled pavilion layout, creating a marriage of blazing surface sparkle and deep internal fire. Each facet has been placed and polished to exacting standards so that light enters, is redirected through the pavilion, and returns in dynamic flashes that change with movement. Where many sapphires on the market suffer from shallow or poorly matched facets that leak light, this gem’s geometry maximizes light return and contrast, producing crisp scintillation and a lively play of color across the table and the crown. The excellent polish further enhances this effect, delivering mirror like flashes that give the stone an apparent brightness beyond what its carat weight might suggest.

Clarity and overall appearance are often the deciding factors when choosing a sapphire, and this greenish blue example is graded very slightly included when evaluated at eye level. That designation means the stone is largely clean to the naked eye, with only minor inclusions that do not interrupt its transparency or diminish its striking color. In practical terms, you get the advantage of a sapphire that retains a glass like window into its depths, while still being an authentic natural crystal with the character that collectors value. In contrast to heavily included or fracture filled stones that can look cloudy or lifeless, this sapphire maintains crisp facet definition and intense color saturation. Its intense color intensity offers a level of visual saturation that reads as deep and luxurious, while remaining flexible enough to flatter many metal choices and skin tones.

From a value and design perspective, this Madagascar sapphire is a superior choice. The combination of natural origin, no enhancement, precise mixed brilliant cutting, and excellent polish results in a gem that performs like a larger stone, thanks to efficient light return and impactful color. It will outshine many similar weighted stones that are either over treated, poorly cut, or heavily included, and it holds strong provenance in a respected natural source. For clients seeking a distinct, high performing center stone, this sapphire makes a compelling statement without the premium you would pay for the very largest examples. If you are designing a bespoke ring, considering an heirloom piece, or selecting a gemstone investment, The Natural Sapphire Company welcomes you to examine this gem more closely, and to view additional images and setting suggestions that best showcase its geometric faceting and luminous presence.
