1.00 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a transparent natural blue sapphire of 1.00 carat, presented in a classic oval shape and measuring 6.17 by 5.19 by 3.89 millimeters, with a mixed brilliant cut that balances faceted sparkle with depth of color, and an excellent polish that enhances surface luster. Origin is Ceylon, Sri Lanka, a region long respected for producing a wide range of blue sapphire hues, and this stone carries that provenance clearly in its material character. Clarity has been graded as slightly included, evaluated at eye level, which indicates the presence of minor internal characteristics that are visible under close inspection but do not dominate the overall appearance. There has been no enhancement to this gem, which means the color and clarity are entirely natural, and the absence of treatment contributes directly to the stone's rarity and collectible value. This description is provided by The Natural Sapphire Company as part of a detailed technical presentation for collectors, designers, and connoisseurs who require precise information for evaluation and setting.

The color is a defining attribute of this sapphire, described as dark in intensity, with a deep blue saturation that is less commonly encountered in Ceylon material at this size range. Many sapphires from Ceylon exhibit lighter cornflower and medium blue tones, particularly in weights around one carat, and darker stones of even saturation often come from different localities or at larger sizes where depth can be achieved without sacrificing transparency. This particular stone combines a strong, dark color intensity with transparency and a clean surface presentation, a combination that is comparatively rare among one carat sapphires and that sets this gem apart from typical market offerings. The hue leans toward classic blue without dominant secondary modifiers, and the dark intensity gives the gem an appearance that reads as both richly saturated and stable under varying light conditions. For clients seeking a deep blue sapphire in a modest and wearable size, this example represents an uncommon intersection of tone, transparency, and origin.

The mixed brilliant cut has been executed to balance light return with the need to conserve weight and preserve color, which is especially important in sapphires where cutting decisions directly affect perceived saturation. Faceting is oriented to present scintillation across the table and crown facets while allowing the pavilion to transmit the deep body color, and the excellent polish ensures that each facet meets its neighbor smoothly, contributing to overall brilliance and minimal light leakage. The slightly included clarity grade should be considered in the context of the gem as a whole, because inclusions can influence appearance differently depending on their size, position, and orientation relative to facet junctions. In this stone, inclusions are present but do not materially compromise the gem when viewed at normal conversational distance, and they are consistent with natural formation processes typical of Sri Lankan sapphires. The dimensions of 6.17 by 5.19 by 3.89 millimeters make this sapphire suitable for a variety of settings, including classic solitaires, three stone arrangements, and elegant bezel mounts, and its proportions allow for secure placement with minimal sacrifice to the visual balance of the surrounding metal.

Provenance and treatment status are central to assessing value and suitability for long term ownership, and this sapphire’s origin in Ceylon and its no enhancement declaration provide a clear statement about its natural history. Natural, untreated sapphires with a dark, saturated blue at the one carat weight are encountered less frequently than their lighter counterparts, and this relative scarcity is a significant factor for collectors and designers who prioritize natural state and rarity. Practical considerations for care include routine cleaning with warm water and mild detergent, and cautious handling to avoid hard knocks, as with any corundum, although sapphire is a durable gemstone suitable for daily wear. Documentation provided by The Natural Sapphire Company will describe the gem’s measured attributes and clarity assessment, and additional gemological reports can be supplied upon request to support provenance and treatment status. For professionals evaluating stones for bespoke settings or for private collectors seeking distinctive, naturally colored material in a wearable weight, this sapphire offers a measured and verifiable combination of dark color intensity, natural origin, and careful cutting that is uncommon in the one carat size range.
