7.94 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a precise and well documented example of classic Ceylon blue, weighing 7.94 carats and cut to an elongated oval measuring 12.37 x 10.61 x 7.76 mm, with a mixed brilliant facet arrangement and an excellent polish. The combination of the mixed brilliant cut and the oval outline is designed to maximize both scintillation and color saturation, and in this instance the pavilion and crown faceting work together to produce lively light return while preserving the vivid color intensity that collectors and connoisseurs prize. Transparency is notable, the stone reads as transparent rather than heavily included, and the clarity has been evaluated as very slightly included at eye level, which means that under normal viewing conditions the inclusions do not detract from the stone s visual appeal or overall performance. This sapphire has been heat treated, a standard and stable enhancement in the trade used to improve color and clarity, and the reported origin is Ceylon, Sri Lanka, a source long celebrated for producing sapphires with lively, vivid blue tones and fine overall crystallographic quality.

For an educated buyer assessing suitability for an engagement ring, several objective factors make this stone particularly compelling. The weight of 7.94 carats paired with the 12.37 by 10.61 mm face size provides a commanding presence on the finger without being unwieldy, and the 7.76 mm depth contributes to a solid pavilion that supports secure mounting options. The clarity described as very slightly included at eye level indicates inclusions are minimal and typically not structurally significant for a corundum gemstone, and because sapphire rates nine on the Mohs hardness scale, it is exceptionally well suited for everyday wear compared with many alternative gemstones. The mixed brilliant cut is a thoughtful choice for a center stone intended for a ring, because the small crown facets and well proportioned pavilion facets create a balance between brilliance and color consistency, avoiding the washed out appearance that can occur when light leakage is excessive. From a gemological and ethical perspective, the disclosure of heat treatment and origin matters to well informed purchasers, and heat treatment that is identified and stable maintains strong market acceptance while Ceylon provenance often commands premium interest due to its historical reputation for vivid blues that retain brightness even under varied lighting conditions.

When considering this gem as the centerpiece for an engagement ring, The Natural Sapphire Company offers both the provenance transparency and the design guidance that an educated buyer will value. The combination of weight, shape, cut, and polish yields a sapphire that performs beautifully in a variety of settings, from a refined solitaire that emphasizes the stone s pure color and form, to a delicate halo or three stone design that will increase perceived size while preserving the stone s optical depth. For practical mounting considerations, a secure four or six prong setting, or a low profile bezel that still allows light to enter the pavilion, will protect the stone while maximizing its display on the hand. We recommend a metal such as platinum or high karat gold to complement the vivid blue, and The Natural Sapphire Company can provide bespoke mounting and matched diamond accents to suit stylistic and budget preferences. We are able to supply independent gemological reporting upon request, full disclosure of treatment and origin documentation, and consultation on the most appropriate setting to ensure longevity and wearability. For clients seeking an engagement center stone that combines impressive size, authoritative gemological attributes, and the enduring symbolism of sapphire for fidelity and permanence, this 7.94 carat Ceylon blue sapphire represents an exceptional and trustworthy choice.
