20.59 Ct. Aquamarine from Brazil

This exceptional aquamarine is an invitation to own something truly rare, one transparent 20.59 carat cushion shape gem that arrives to you from the celebrated mines of Brazil. Sized at 16.95 x 14.96 x 12.79 mm, this is a substantial stone whose presence is immediately felt the moment it is set. The mixed brilliant cut gives a modern yet classic geometry to the cushion outline, combining generous facets that capture light with a pavilion designed for maximum depth and scintillation. Evaluated at eye level and graded as eye clean, the clarity of this gem ensures an unobstructed window into an intense sea blue color that reads as pure and vivid. The polish on this gem is excellent, providing a mirror like face that enhances the visual impact of every facet, and the transparent nature of the material allows the color to glow from within. Heat treatment has been applied to enhance the blue tone, a standard and stable enhancement that reveals the truest possible expression of this aquamarine, and each detail of the stone has been carefully examined and prepared by skilled cutters to balance weight retention with optimum optical performance.

When you place this aquamarine within any jewelry setting the result is nothing short of transformative, it will stand out in solitaire rings, dramatic pendants, or as the central stone in a bespoke cocktail piece. The intense color intensity means that this gem maintains a rich, even blue that registers brilliantly against warm and cool metal tones alike, offering versatility for designers and collectors who demand both impact and refinement. The cushion proportions and mixed brilliant faceting produce a lively interplay of flashes and broad color windows, ensuring visibility of color and sparkle from every angle. Because the gem is eye clean, the light travels through freely, generating a lively aqua fire that uplifts skin tones and commands attention even from across the room. For those who wish to emphasize size and presence, a low profile bezel or a streamlined four prong setting will emphasize the stone body while allowing maximum light return. For those who desire a more ornate bespoke creation, a halo of gently sparkling melee will serve to frame the aquamarine without diluting its striking blue, preserving the singular focus on this unique centerpiece.

The Natural Gemstone Company presents this one of a kind piece as a rare opportunity for discerning collectors and connoisseurs of fine colored gemstones, this is not a stock item to be replicated, it is a singular gem with provenance, pedigree, and personality.
