1.75 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.75 carat blue sapphire has been cut into a classical emerald cut shape, with measured dimensions of 7.90 by 5.94 by 3.97 millimeters, and originates from Ceylon, Sri Lanka. At first glance the gem presents a vivid intensity of blue that speaks to strong saturation and appealing hue, balanced against excellent transparency. The clarity grade is eye clean when evaluated at eye level, meaning that no inclusions are visible to the unaided eye under normal viewing conditions, and the stone displays an excellent polish that produces crisp facet reflections and a clean surface lustre. This sapphire has been heat treated, which is a widely accepted and stable enhancement in the trade that improves color and overall appearance, and this treatment is fully disclosed by The Natural Sapphire Company to maintain transparency with collectors and connoisseurs.

The geometric faceting of this emerald cut sapphire has been executed to maximize light play while preserving the depth of color that makes Ceylon sapphires desirable. Emerald cuts employ long step facets on the crown and pavilion that create broad flashes of light, and when the proportions are carefully controlled these steps act like a series of mirrors that return light in broad, even planes. In this stone the generous table and well proportioned pavilion depth allow for strong light return and an even distribution of blue across the surface, so the viewer sees both lively internal reflections and a deep, velvety field of color. Because the emerald cut emphasizes clarity and color rather than scintillation alone, it allows the vivid saturation of this Ceylon sapphire to be admired without the distraction of excessive sparkle, making it ideal for settings where color presence and elegant geometry are the priority.

Clarity and polish are central to the perceived value of a sapphire, and an eye clean grade at standard viewing distances materially enhances desirability for an educated buyer. The lack of visible inclusions means that light can traverse the stone with minimal scattering, which intensifies color saturation and produces a clean, lively appearance. Excellent polish further amplifies these effects by ensuring that facet junctions are sharp and surfaces are smooth, which increases contrast between facets and strengthens the gem s light return. Heat treatment in sapphires is a stable enhancement that penetrates the crystal lattice to modify color centers, and when performed by experienced lapidaries it produces a natural looking and durable result. Disclosure of heat treatment is part of ethical trade practice, and The Natural Sapphire Company provides full transparency about this stone s enhancement history to support informed purchasing decisions.

The Ceylon origin of this sapphire contributes both to its aesthetic profile and to its market position. Sri Lankan deposits are renowned for producing sapphires with a luminous, medium to vivid blue that often shows a slight velvety quality and excellent clarity. The geological conditions in Ceylon yield material that balances strong hue with good transparency, which is evident in this specimen. For the collector or the buyer seeking an investment grade gem, origin matters because it informs expectations about color behavior, potential for secondary hues, and historic desirability. The carat weight of 1.75, combined with the nearly eight by six millimeter footprint and prudent depth, makes this stone versatile for a variety of settings. It will sit prominently in a solitaire ring, complement a halo design where the emerald cut s clean lines contrast with round or baguette accents, or be set as the centerpiece in custom commissions where proportion and symmetry matter.
