1.07 Ct. Blue Aquamarine from Brazil

This transparent 1.07 carat princess shape blue aquamarine measures 5.95 x 5.94 x 4.90 mm, exhibiting precise square geometry and tight symmetry. The faceted princess cut displays crisp pavilion facets that converge to a sharp culet point, and a well formed crown with evenly graduated star and kite facets that maximize light return. Clarity is graded eye clean at eye level, indicating an absence of visible inclusions that would interfere with transparency or facet contrast. The color is a light blue with even saturation across the table and pavilion, a hue that reads as pure aquamarine rather than greenish or overly washed, and the finish shows excellent polish with clean facet junctions and mirror like facet planes. No enhancement has been applied, the stone is natural, and its Brazilian origin is consistent with the clean crystal habit and stable light blue tone typical of fine Brazilian aquamarine deposits.

From a gemological perspective this piece is notable for a combination of attributes that are rare in this size and shape. Princess cut aquamarines of approximately one carat are uncommon in the market, because cutters more often preserve weight in step cuts or oval shapes for beryl. Achieving a well proportioned princess cut at 1.07 carat requires careful planning to retain both color and clarity while forming the square outline and the precise facet architecture. The absence of treatments increases rarity, because many aquamarines are heat treated to deepen blue tones. This untreated, eye clean specimen offers natural color integrity, which makes it significantly more desirable relative to similar size material that is either paler, included, or heat modified.

At The Natural Gemstone Company we highlight technical performance for set design and craftsmanship. The stone’s excellent polish and stable light blue intensity render it ideal for contemporary solitaire or halo settings, where the square pavilion and even crown will align precisely with bezel or prong work. With a refractive index typical of beryl, low dispersion, and a durable hardness suitable for daily wear, this aquamarine combines practical wearability with collector grade attributes. For clients seeking a compact, square blue beryl that is untreated, eye clean, and precisely executed, this 1.07 carat princess aquamarine represents a rare and technically refined choice.
