Product description

I am pleased to present a genuinely rare offering from The Natural Sapphire Company, one beautiful translucent 3.40 carat cushion shape blue sapphire presented in a sugar loaf cut. This gem measures 9.22 by 7.22 by 5.03 millimeters, and its generous proportions and gentle domed profile create a presence that is immediately commanding yet quietly refined. Only a select number of sugar loaf sapphires of this size, with such vivid blue saturation and a high level of translucency, appear on the market each year. For collectors and clients who seek the singular, this piece represents an opportunity to own a stone that feels private and exclusive, a gem that will subtly declare distinction without overt display. At The Natural Sapphire Company we curate these rarities with care, ensuring that each gem we offer has provenance, character, and the potential to become an heirloom.

The color of this sapphire is where its personality truly reveals itself, vivid in intensity and anchored in a classic, deep blue that shifts slightly with viewing angle to suggest complexity rather than monotone. The sugar loaf cut enhances the depth of color while allowing light to play across the surface in broad reflections, creating a liquid sheen that seems to move as the gem catches the light. The excellent polish maximizes this luminous quality, giving the stone a mirror smooth finish that emphasizes the clarity and vivid color. The cushion shape provides a balance of classic and contemporary aesthetics, making this sapphire exceptionally versatile. Whether set in a minimalist solitaire to foreground the stone itself, or placed within a more elaborate, bespoke setting to amplify its presence, the visual impact will always read as refined and intentional.

In terms of clarity and treatment, this sapphire is graded very slightly included when evaluated at eye level, an indicator of natural character rather than compromise. These subtle inclusions do not detract from the gem s beauty, and in many cases they contribute to the optical depth that makes natural sapphires so compelling. The stone has been heat treated, a widely accepted and stable enhancement that improves color and clarity in a way that is both permanent and predictable. Origin is Tanzania, a source known for producing sapphires with rich, velvety blue tones and a distinct sense of depth. The combination of Tanzanian origin, sugar loaf cutting tradition, and a careful heat treatment results in a gem that is both naturally expressive and fully ready to be set into a lifetime piece. We always advise gentle daily care and professional cleaning for heat treated sapphires to preserve their polish and luster.

Owning this sapphire means joining an elite circle of collectors and connoisseurs who value authenticity, rarity, and meticulous craftsmanship. The Natural Sapphire Company stands ready to translate this stone into a bespoke creation, whether you envision a modern statement ring, a timeless pendant, or a custom design that echoes family history. We provide tailored consultations to discuss setting options, metal choices, and design details so the final piece complements the sapphire s natural virtues while reflecting your personal style. For discerning clients who understand that true rarity is not merely about size but about character and provenance, this sugar loaf cushion sapphire is an invitation. Securement of such a rare gem is inherently limited by nature, and our access to pieces of this quality is intentionally selective. If you would like to explore this sapphire further, request detailed imagery, or arrange a private viewing, we would be honored to assist you.
