2.13 Ct. Blue Aquamarine from Mozambique

This listing describes one transparent natural aquamarine, oval shape, weighing 2.13 carats, with exact dimensions 9.73 by 7.85 by 5.18 millimeters. The stone is faceted in a french cut, with an excellent polish that contributes to even light return across the table and crown facets. Clarity is reported as very very slightly included, evaluated at eye level, and these minor internal characteristics do not materially affect transparency or brilliance when the gem is set. Color intensity is light blue, with cool sea-blue tone typical of aquamarine from Mozambique. Enhancement is by heat treatment, a stable, widely accepted process used to remove greenish undertones and refine the blue hue, and the declared origin is Mozambique. The presentation photography includes hand-scale images that illustrate the gem’s face-up size and proportions for common ring settings.

Optical and physical attributes of this aquamarine make it well suited to a variety of fine jewelry applications. The oval outline and the proportions indicated by the 9.73 by 7.85 millimeter table and 5.18 millimeter depth create a pleasing spread for a 2.13 carat stone while maintaining good face-up brilliance. The french faceting emphasizes a clean, geometric facet pattern that produces crisp light reflections and a slightly classical appearance when compared to modern mixed cuts. Aquamarine is a variety of beryl with a Mohs hardness of approximately 7.5 to 8, providing good durability for daily wear when set with reasonable care. The excellent polish and the stone’s transparency allow the subtle light-blue color to read clearly under both natural and artificial lighting, and the modest eye-visible inclusions contribute to natural character without compromising optical performance.

When compared to lab-grown gemstones, this natural aquamarine offers several distinct advantages that are relevant to collectors, jewelers, and purchasers concerned with provenance and long-term value. Lab-grown beryls can deliver uniform color and minimal inclusions at lower cost, and they are valuable options when consistency and budget are primary considerations. Natural stones, by contrast, carry intrinsic geological history, including unique inclusion patterns and growth features, which function as a fingerprint of natural formation and provide individuality that cannot be perfectly reproduced in a laboratory. Natural aquamarines from specific localities, such as Mozambique, can command additional interest due to locality recognition, and treated natural stones commonly retain stronger value resilience in the secondary market than synthetic material. The Natural Gemstone Company documents origin and noted enhancement, providing transparent information so that the buyer understands both the stone’s natural provenance and the stable heat treatment that enhances color.

Practical considerations and care are straightforward for this aquamarine. The dimensions and oval outline make the gem appropriate for solitaire rings, three-stone shoulder settings, and pendant designs where the controlled depth and faceting deliver predictable light performance. For everyday rings, consider protective settings such as a bezel or lowered prongs to reduce the risk of edge contact, while still allowing the table and crown facets to display the stone’s blue tone. Heat treatment performed prior to sale is a permanent enhancement; standard jewelry care applies, including avoiding harsh chemicals and ultrasonic cleaning only when the setting and any accompanying stones permit.
