2.60 Ct. Blue Aquamarine from Madagascar

This exceptional 2.60 carat cushion shape aquamarine from Madagascar is presented by The Natural Gemstone Company as a transparent, natural, untreated gemstone with precise dimensions of 8.74 by 7.68 by 6.27 millimeters. The mixed brilliant cut employed for this stone marries a faceted brilliant crown with a carefully faceted pavilion to maximize return of light and scintillation, producing a lively yet refined face-up appearance. The medium color intensity is an appealing light to medium blue, balanced between the paler pastel tones and the deeper sea-blues that collectors prize, and because this aquamarine is unenhanced, the color you see is wholly natural. The gem’s weight and proportions deliver a satisfying presence suitable for a prominent solitaire, a halo ring, or a bespoke pendant, and the depth of approximately seventy-six percent contributes to both color saturation and a strong visual depth when set.

From a clarity and optical character perspective this aquamarine is graded slightly included when evaluated at eye level, a designation that conveys high clarity with modest internal features visible only on close inspection or under magnification. Slightly included aquamarines typically show small crystalline inclusions, faint growth zoning, or minute two-phase liquid inclusions, and in this specimen those features act as natural fingerprints, certifying its origin and authenticity. These inclusions do not materially compromise brilliance or transparency, and in many cases they enhance the gem’s individuality and provenance, telling a geological story of formation deep within Madagascar’s pegmatitic or granitic host rocks. For the educated buyer, such internal characteristics are desirable as provenance markers, and they provide assurance that the stone is a natural, untreated aquamarine rather than a laboratory-modified or synthetic material.

Cutting quality and surface finishing are crucial in translating a gem’s inherent properties into wearable beauty, and this aquamarine exhibits an excellent polish that produces crisp facet junctions and lively light performance. The mixed brilliant faceting pattern has been executed to emphasize both sparkle and color, with the crown facets dispersing highlights across the table and the pavilion facets creating depth and return. The excellent polish ensures minimal surface abrasions and superior luster, making this stone extremely wearable. The cushion outline remains modern and versatile, and the slightly deeper pavilion gives the gem a rich body color without appearing overly dark in hand. For everyday use, aquamarine’s hardness in the beryl family, typically between 7.5 and 8 on the Mohs scale, affords good durability for rings and pendants when set with protective settings, and the dimensions of this gem make it straightforward to secure in a bezel, prong, or hybrid setting depending on design preferences.

Care and value considerations are important for the discerning buyer. Because this Madagascar aquamarine has not been subjected to color enhancement techniques such as heat treatment, its untreated status adds premium value among collectors and connoisseurs who prioritize natural gems. To maintain the stone’s beauty, clean with warm water, mild soap, and a soft brush, and avoid harsh chemical exposure or prolonged ultrasonic and steam cleaning unless advised by a qualified jeweler familiar with the specific inclusions present. When selecting a mounting, consider protective prongs or a bezel for a ring to shield the corners of the cushion shape, while a well-crafted pendant setting will showcase the gem’s clarity and light return. At The Natural Gemstone Company we emphasize transparency about each gem’s origin, cut, clarity, and finishing, and this aquamarine’s combination of natural Madagascar origin, mixed brilliant faceting, slightly included authenticity, and excellent polish makes it an excellent choice for an educated buyer seeking a durable, attractive, and verifiably natural aquamarine that carries both aesthetic appeal and geological provenance.
