1.63 Ct. Blue Aquamarine from Madagascar

This listing describes a single transparent aquamarine from Madagascar, presented by The Natural Gemstone Company. The stone weighs 1.63 carats, and measures 9.14 by 6.09 by 4.41 millimeters. It is fashioned into an emerald cut, exhibiting the stepped pavilion and truncated corners characteristic of this cut class. The color is a light blue with a gentle, cool tone that is evenly distributed across the table and facets. Clarity is graded as slightly included when evaluated at eye level, and the finish carries an excellent polish. There has been no enhancement applied to this gem, and the natural state is a defining attribute of its appeal.

The emerald cut emphasizes clarity and face up size, and in this instance the proportions produce a broad table and a length to width ratio that reads as elegant and restrained. The precise faceting and excellent polish contribute to clean facet junctions and consistent light return without excessive scintillation, which suits the aquamarine aesthetic. The light color intensity allows the gem to retain a clear and airy presence while remaining distinctly blue, which adapts well to a range of mounting styles and metal choices. Given the listed dimensions, the stone will occupy a notable but refined footprint on the finger, with the elongated geometry of the emerald cut enhancing perceived size and creating a classical profile.

Inclusions are present at a level consistent with a slightly included grade at eye level, and these internal features function as unique identifiers that add to the stone character. Inclusions in beryl species, which include aquamarine, typically appear as small crystals, narrow tubes, or minute two phase elements, and they record the conditions of growth deep within the earth. For this emerald cut aquamarine the inclusions can be read as a natural fingerprint, confirming the gem origin and proving its natural formation. These features impart subtle depth and natural texture to the interior, and when viewed under magnification they provide a fingerprint that is useful for identification and provenance work. The presence of inclusions at this degree does not materially compromise structural integrity, and the excellent polish and skilled cutting minimize any visual distraction when the gem is set and viewed in normal light.

Handling, mounting, and care recommendations are provided to preserve the condition of the gem. The stone is unheated and untreated, so standard precautions for beryl apply, avoid harsh blows and sudden thermal shock, and clean periodically with warm soapy water and a soft brush. For daily wear consider settings that protect the girdle and corners, such as a bezel or a protective prong design that supports the truncated corners of the emerald cut. When mounting, consult a qualified jeweler to ensure that the inclusions are not placed in positions that might be exposed to impact risk. The Natural Gemstone Company sources this gem from Madagascar with attention to ethical procurement and documentation, and we can assist with additional photographic or report level information upon request. This aquamarine represents a natural, unenhanced example of the species, with measured proportions, a light and clear blue color, and internal characteristics that testify to its geological history.
