0.93 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This precisely cut, transparent round blue sapphire weighs 0.93 carat, and measures 5.57 by 5.55 by 3.86 millimeters. The cutting style is faceted with a mixed brilliant cut, and the surface finish is listed as excellent polish. Clarity has been evaluated at eye level as very slightly included, offering a balance between natural character and visual purity. Color intensity is described as intense, and the stone has been heat treated, which is the industry standard enhancement for improving both color and clarity. The origin is Ceylon Sri Lanka, a source long admired for producing sapphires with lively, saturated cornflower and royal blue tones. At The Natural Sapphire Company we select pieces with not only aesthetic appeal, but also with technical attributes that matter to the informed buyer.

When assessing the gem, the mixed brilliant cut and the excellent polish work together to maximize light return and dispersion. The mixed brilliant cut blends step cut facets on the pavilion with brilliant facets on the crown, which helps to combine strong scintillation with a pleasing, even color face up. The dimensions indicate a well proportioned round that preserves weight while avoiding the shallow or deep extremes that can mute brilliance. The very slightly included clarity means that under unaided eye examination a few tiny inclusions may be present, but they do not detract from overall visual impact. For a graduate level or connoisseur buyer, these inclusions can actually serve as a fingerprint of natural origin, and they confirm that the stone has not been overly fractured or filled during enhancement.

Under varying lighting conditions this sapphire reveals different aspects of its beauty, giving the wearer a versatile and dynamic look. In strong natural daylight, especially under north light or overcast sky, the intense blue will appear rich and saturated, with deep body color that remains even across the table. In direct sunlight the mixed facet pattern creates lively scintillation and small flashes of brighter blue, which enhances perceived fire without washing out the hue. Under warm incandescent lighting, the stone tends to lean toward a warmer royal blue, with slight hints of violet depending on the angle, making it appear lush and velvety. Under cool white LED or fluorescent lighting the cooler tones are emphasized, producing a crisper, electric blue that reads as very clean and highly saturated. In soft candlelight the lower intensity light brings out depth more than sparkle, giving a luxurious, deep blue presence that is subtle and intimate. This variety is typical of high quality Ceylon sapphires and adds to the stone value for those who appreciate color response in real world settings.

From the perspective of investment and long term enjoyment, several technical factors make this sapphire attractive to an educated buyer. The Ceylon origin is associated with a particular color profile that is highly sought after in the market, and when combined with a strong face up color intensity and an excellent polish, it positions the stone favorably against comparable material. Heat treatment is widely accepted in the trade when fully disclosed, because it produces stable improvements to both color and clarity without compromising the structural integrity of corundum. Corundum is durable with a Mohs hardness of nine, which means the stone is suitable for daily wear in rings as well as for pendants and earrings, provided normal care is taken. The modest size of 0.93 carat in a well cut round is efficient for settings where balance and symmetry are valued, and it offers more color saturation per point than some larger but poorly proportioned stones. Collectors and jewelers often prefer such stones for bespoke settings because the proportions lend themselves to consistent light performance while keeping metal weight and overall scale elegant.

Care, setting, and provenance matter to preserve both beauty and value, and The Natural Sapphire Company provides full disclosure of treatments and origin for this gem. Routine cleaning with warm soapy water and a soft brush is effective for maintaining brilliance, and professional ultrasonic cleaning may be used with caution if the stone is securely set and no additional filled fractures are present, as disclosed. When setting in jewelry choose a mounting that protects the girdle and allows light to enter the crown, as the mixed brilliant design benefits from unobstructed crown facets. For the buyer seeking an heirloom quality, the combination of intense Ceylon color, excellent polish, a precise mixed brilliant cut, and transparent eye cleaned appearance makes this sapphire a compelling option. At The Natural Sapphire Company we stand behind the gemology and provenance of each stone, and we invite you to consider this 0.93 carat Ceylon blue sapphire for a custom piece that will continue to reward the eye under every type of lighting.
