1.01 Ct. Greenish Blue Sapphire from Madagascar

This entry grade, heart shape natural sapphire is a precisely described example of quality and character, offered by The Natural Sapphire Company. The gem weighs 1.01 carats, and measures 5.66 by 5.96 by 4.28 millimeters. It is transparent, with an intense greenish blue hue that carries both depth and clarity. The stone is fashioned in a mixed brilliant cut, combining pavilion and crown faceting to maximize light return while preserving the heart outline. Clarity is graded as very slightly included, evaluated at eye level, and the surface shows an excellent polish. There has been no enhancement, and the material originates from Madagascar, a source increasingly recognized for distinct and richly colored sapphires.

Visually the sapphire presents a concentrated, saturated color that reads as greenish blue rather than a simple blue, which imparts notable individuality and versatility in design. The mixed brilliant cut produces a complex array of small facets on the pavilion and larger facets on the crown, creating a balance between broad flashes and fine scintillation. Because the gem is transparent and the clarity is very slightly included at eye level, light travels through the body of the stone with minimal obstruction, so color and brightness remain consistent across the table and through the lobes of the heart shape. The precise dimensions support a well proportioned face up presentation, allowing the heart silhouette to remain instantly recognizable while maintaining optimal optical performance. The excellent polish enhances facet contrast and surface reflection, contributing to a crisp, lively appearance under varied lighting conditions.

When compared with more common gemstones, this sapphire exhibits a distinct type of brilliance and appeal. Diamonds, with their higher refractive index, produce a pronounced white sparkle and strong dispersion that breaks light into spectral flashes. Sapphires, by contrast, have a lower refractive index, and therefore show less white fire, yet they offer greater color saturation and a different kind of brilliance that emphasizes hue and depth rather than purely white light return. Compared with aquamarine and blue topaz, which typically present paler, more pastel tones and a broader, softer glow, this greenish blue sapphire stands out for its intense color intensity and concentrated saturation. The mixed brilliant cut enhances scintillation in a way that approaches the lively contrast associated with more strongly refractive gems, but the visual impact is derived from vivid color centers and well defined facet reflections rather than solely from dispersion. In practical terms the sapphire will read as a richer, more substantial color presence on the hand or in a bezel, offering a sense of depth and life that paler stones seldom match. The lack of enhancement further differentiates this gem from many commercial sapphires, because natural, untreated color and clarity are relatively rare, and this contributes to its desirability for clients seeking authenticity.

From a gemological and practical perspective, the attributes of this piece make it suitable for fine jewelry applications where longevity and visual performance are priorities. The heart shape communicates sentiment while the one carat weight and compact dimensions make the stone adaptable to a range of settings, from a classic solitaire pendant to a refined engagement ring with protective prongs. The mixed brilliant cut and excellent polish mean that the jewel will maintain attractive light behavior in daily wear, and the very slightly included clarity grade suggests that inclusions will not distract at typical viewing distances, while still confirming the natural origin of the stone. The Madagascar provenance is notable because deposits there produce a wide spectrum of unique sapphire colors, and stones from this region are increasingly valued for their distinctive tones and natural brilliance. For clients and designers who value traceable origin and untreated material, this sapphire represents a considered selection.

The Natural Sapphire Company provides full disclosure of the gem specifications to support informed evaluation and design planning. The information on weight, measurements, cut style, clarity assessment, polish, color intensity, lack of enhancement, and origin allows jewelers and clients to anticipate the stone behavior and to choose complementary settings that preserve both appearance and integrity. In summary, this 1.01 carat greenish blue heart shape sapphire combines intense natural color, finely executed mixed brilliant faceting, and a clean, well polished surface to deliver a gem that stands apart from paler commercial blues and from colorless stones that rely primarily on dispersion. Its untreated status and Madagascar origin add to its appeal for collectors and for those seeking an expressive, enduring center stone.
