1.70 Ct. Blue Sapphire from Ceylon (Sri Lanka)

When you are searching for a sapphire that ends your quest for depth, character, and wearable brilliance, this Other certified Blue Royal Blue sapphire from The Natural Sapphire Company answers that need with confidence and grace. We understand that choosing a stone is about more than specifications, it is about the feeling you want to carry every day, the milestone you want to mark, and the legacy you want to pass on. This transparent royal blue sapphire, weighing 1.70 carat, presents an immediate impression of rich, vivid color that sits between the classic cornflower blues and the deeper, more dramatic tones coveted by collectors and connoisseurs. Its oval shape and refined proportions make it an ideal choice for a striking solitaire engagement ring, a sophisticated three stone design, or a bespoke piece for a collector who values traceable origin and expert craftsmanship.

The gemology details make the quality visible and reassuring, this sapphire is cut to an elegant mixed brilliant style, measuring 8.37 by 5.58 by 3.93 millimeters, with a clarity grade of slightly included at eye level, vivid color intensity, and an excellent polish that translates into lively reflections and precise facet brightness. The gem has been heat treated, a stable enhancement that refines tone while preserving the natural character of the stone, and it carries a Ceylon Sri Lanka origin that speaks to centuries of known sapphire excellence. When comparing its hue and tone to sapphires from famous locations, it reads as a Ceylon that leans toward royal blue rather than the typically lighter, more cornflower leaning tones many people associate with Ceylon classics. Against a Kashmir sapphire this stone is less velvety, with more saturated vibrancy and slightly more transparency, and compared to Burmese sapphires it is often a touch brighter and cleaner in midtones, while offering comparable depth in the darker areas.

Seeing how a stone behaves in different lights often seals a customer decision, and this sapphire shows an attractive balance between body color and pavilion reflections, bringing vivid blue across daylight and a richer, deeper blue under evening and artificial lighting. In visual comparison to other notable sources, this gem offers clearer midtone luminosity than many Madagascar sapphires which can lean toward bluish violet, and it is more luminous in midtones than the inky, darker blues common to Australian stones, while remaining more saturated than the steely blue shades that come from Montana deposits. These comparisons help you anticipate how the gem will wear on the hand, and in practice the dimensions and mixed brilliant cut deliver a sparkle that complements the rich royal hue, making it easy to design settings that highlight both the interior fire and the smooth outer color. The slightly included clarity grade contributes to the natural identity of the stone, and when set with an open gallery or minimal bezel the inclusions remain discrete, allowing the vivid color to remain the focal point.

For couples seeking an engagement ring that communicates permanence and refined taste, and for collectors who want a rare royal blue Ceylon sapphire that is both wearable and investment worthy, this 1.70 carat oval sapphire is a thoughtful solution. Envision it set in platinum to emphasize the cool, royal tone, or in warm yellow gold to introduce contrast that intensifies perceived saturation, both approaches popular among our clients who rely on The Natural Sapphire Company for curated, origin certified gems. Our team can guide you toward settings that protect the stone while maximizing light return, and we recommend a low profile yet secure mounting to show the oval silhouette and preserve daily wearability. This sapphire carries provenance, excellent polish, and the kind of vivid color intensity that stops people on sight, and with our expertise we help you choose a setting and final presentation that turns the stone into a personal heirloom.

Choosing a stone should feel decisive and supported, and The Natural Sapphire Company is here to make that choice as confident as possible, from gemological clarity about enhancements and origin, to practical recommendations for secure and flattering settings.
