3.00 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This gem is a transparent 3.00 carat emerald cut shape color change sapphire, with precise dimensions of 8.47 x 7.47 x 4.87 mm, originating from Ceylon Sri Lanka. The stone displays a vivid color intensity, and it has been carefully heat treated, a widely recognized and stable enhancement for sapphires. Its clarity grade is very very slightly included, evaluated at eye level, reflecting the natural character of the material while maintaining visual purity. The polish on this sapphire is excellent, and the step cut geometry of the emerald shape provides a refined outline and a disciplined interplay of light across the table and steps, creating a restrained yet luminous presence. This description accompanies the gem offering from The Natural Sapphire Company, and it emphasizes verifiable attributes and provenance.

The emerald cut shape emphasizes transparency and clarity through its elongated rectangular outline and parallel step facets, which produce broad flashes of light rather than scintillation typical of brilliant cuts. With dimensions of 8.47 x 7.47 x 4.87 mm the gem possesses balanced proportions that support an elegant profile and comfortable practical use in a variety of mounting styles. The step facet arrangement tends to present color zones in a calm, linear fashion, permitting the vivid color intensity to be observed uniformly across the table when viewed face up. Excellent polish ensures the facet junctions are clean and precise, enhancing the apparent depth and allowing the stone to present its optical characteristics without interference from surface irregularities.

Color change sapphires are prized for their ability to display different hues under varying lighting conditions, and this specimen’s vivid color intensity amplifies that phenomenon. In mixed or natural daylight environments the stone will present one aspect of its hue spectrum, while incandescent or warm artificial lighting will reveal another phase of its color character, creating an engaging visual shift. This property may be subtle or pronounced depending on viewing context, and because the change is inherent to the crystal chemistry of the corundum host, it remains a persistent and reliable feature over time. The heat treated enhancement performed on this sapphire is standard industry practice for improving clarity and color uniformity, and it does not undermine the stability of the color change effect under normal wear conditions.

Clarity graded as very very slightly included evaluated at eye level indicates that this sapphire contains minor natural inclusions that are not detrimental to its overall appearance or structural integrity. In an emerald cut, where broad facets reveal internal characteristics more readily than a brilliant cut, the presence of small inclusions serves as a natural fingerprint that confirms the gem’s origin and authenticity, while still allowing the wearer to enjoy a clean and transparent presentation. Corundum rates high on the Mohs hardness scale, which contributes to the gem’s suitability for daily wear and long term durability, provided reasonable care is observed. Routine cleaning with warm soapy water and a soft brush will preserve surface luster, and professional inspection by a trusted gemmological service will help ensure settings and polish are maintained, preserving the sapphire’s excellent finish.

The provenance of Ceylon Sri Lanka provides historical and gemmological context, as the region has a longstanding reputation for producing sapphires with fine color and clarity. The combination of the emerald cut form, the vivid color intensity, the very very slightly included clarity evaluated at eye level, and the excellent polish together create a stone that is both visually engaging and fit for long term ownership. The Natural Sapphire Company presents this sapphire with thorough documentation of its measured dimensions, carat weight, and enhancement history, enabling informed consideration. When set with appropriate protective mounting and cared for in accordance with standard practice, this color change sapphire will continue to reveal its nuanced beauty and remain a captivating heirloom quality gem for years to come.
