4.71 Ct. Blue Aquamarine from Brazil

This listing describes one transparent aquamarine of notable size and refined finish, offered by The Natural Gemstone Company. The stone weighs 4.71 carats and is fashioned into a cushion shape with elegant proportions, measuring 13.60 by 9.73 by 5.75 millimeters. The cutting style is a mixed brilliant cut, selected to balance scintillation with broad flash, and the finish is reported as excellent polish. Color is of medium intensity, presenting a clean, classic blue tone that is neither deeply saturated nor overly pale, and the clarity has been evaluated as very very slightly included at eye level, indicating that the gem appears visually clean when viewed without magnification. The specimen originates from Brazil and has undergone a standard heat treatment to optimize hue and saturation, consistent with common practice for aquamarine enhancement.

The cut and faceting on this cushion aquamarine are a defining feature, with a mixed brilliant design that emphasizes both light return and internal fire. The pavilion facets are arranged to promote lively scintillation while the larger crown facets create broad flashes and an open table that allows the color to read evenly across the face of the gem. The cushion outline provides a balance between classical and contemporary aesthetics, giving the piece versatility for a range of design contexts. Precision in facet alignment and symmetry is evident in the photographs, and the excellent polish further contributes to the gem appearing glossy and clean, maximizing the perceived depth and life of the blue tone. For collectors and designers who prioritize optical performance, the combination of a refined cushion outline with mixed brilliant faceting makes this stone a natural centerpiece given its capacity to draw the eye and anchor a composition.

On the matter of clarity color and treatment the stone presents as a high quality example of aquamarine material. The description of very very slightly included evaluated at eye level suggests that inclusions are minimal and do not impact transparency or the overall visual presentation in normal viewing conditions. Under magnification such inclusions may become more apparent, but they are not intrusive to the eye naked, which preserves the gem for fine jewelry applications. The medium color intensity provides a pleasing balance between versatility and presence, enabling the stone to perform well in settings that range from refined day wear to formal evening pieces. Heat treatment is a stable and accepted enhancement for aquamarine, applied to improve blue saturation and to neutralize greenish tones when present, and it does not detract from the structural integrity of the gem. Care recommendations are conventional for beryl class materials, advising protection from prolonged exposure to extreme heat and hard knocks, and routine cleaning with warm soapy water and a soft brush for optimal maintenance.

Given its size proportions and optical attributes this aquamarine functions as a focal element in both bespoke and catalog jewelry designs. The 4.71 carat weight and 13.60 by 9.73 millimeter face dimension place it within a range that is well suited to solitaire rings with substantial presence, to halo treatments that emphasize center stone radiance, and to pendant designs that benefit from an open table and generous table area. The cushion shape integrates readily with a variety of setting geometries, and the mixed brilliant cut provides a lively interaction with light that will remain visually appealing in hand. Photographic scale examples demonstrate how the piece sits when worn and how its proportions read on the finger. The Natural Gemstone Company can provide additional information on mounting recommendations and can facilitate viewing options for interested clients, ensuring that this Brazilian aquamarine can be evaluated in context and considered as a potential centerpiece for an elevated collection.
