1.28 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This parcel contains a one point two eight carat heart shape yellow sapphire, transparent, Other certified Yellow, with precise dimensions of 5.87 by 7.90 by 3.70 millimeters. The stone is fashioned in a mixed brilliant cut, combining faceting styles to enhance both depth and surface scintillation, and it presents a medium intense yellow color that reads consistently across the face up view. Clarity is graded as very slightly included when evaluated at eye level, indicating minor internal characteristics that do not detract from overall visual appeal, and the finish is described as excellent polish, yielding a crisp, unobstructed table window and well defined facet junctions. Origin is Ceylon Sri Lanka, a historic source for yellow sapphires, and the gem is supplied without enhancement, a condition that confirms the natural state of its color and internal structure as seen in our assessment at The Natural Sapphire Company.

The mixed brilliant cut in this heart shape has been executed to balance brilliance and color distribution. The crown facets and pavilion facets work in tandem to optimize light return, creating lively scintillation and a pleasing sense of depth that enhances the medium intense yellow hue. Heart shapes demand careful symmetry to present a balanced lobed outline and a well formed cleft, and this piece shows proportionate lobes with a deliberate weight distribution that complements its size and carat weight. The excellent polish contributes to surface reflection and the perception of clarity, so the very slightly included clarity grade remains a positive attribute, adding character without compromising presence. In hand imagery and loupe assessment the stone exhibits clean facet intersections and minimal windowing, attributes that are often sought for stones intended to function as the focal element in rings or pendants.

Durability is a primary consideration for daily wear jewelry, and this sapphire performs strongly in that regard. As corundum, sapphire rates nine on the Mohs hardness scale, which confers high resistance to scratching from most common materials encountered in everyday life, and its inherent toughness makes it less prone to chipping than many gemstones with similar hardness but lower fracture resistance. The excellent polish and lack of enhancement further reduce the likelihood of surface degradation under normal conditions, because there are no introduced fillings or diffusion treatments that could alter behavior under heat or cleaning. That said, the heart shape presents a pointed lower tip and a cleft at the top, features that are geometrically more exposed to impact than rounded profiles, so a protective setting design is advisable for frequent wear. Recommended approaches include secure prong work that reinforces the tip and cleft, or a bezel style that covers vulnerable edges while still showcasing the face up color and brilliance.

For practical care and setting guidance based on the stone attributes, warm soapy water and a soft brush remain the simplest and safest cleaning method for this untreated Ceylon sapphire, and routine checks of the setting by a qualified jeweler will preserve both stone and mount. Professional ultrasonic cleaning is generally acceptable for natural, non filled sapphires, however it is prudent to consult with an experienced bench jeweler before use, particularly for mounted stones with delicate settings. Design choices that emphasize protection will maximize longevity for daily wear, for example a low profile bezel for active hands, or a secure four prong configuration with reinforced tips that preserve the heart outline while absorbing incidental knocks. The combination of high hardness, good toughness, excellent polish, and absence of enhancement makes this heart shape yellow sapphire a reliable and attractive candidate for everyday jewelry in rings, pendants, and secure bracelet designs.

At The Natural Sapphire Company we document origin, treatment status, and gemological characteristics to support informed decisions for long term wear, and this 1.28 carat heart shape yellow sapphire from Ceylon Sri Lanka reflects our focus on natural material with verifiable provenance. The stone combines desirable optical performance with industry standard durability, and thoughtful mounting will ensure the heart shape remains both visually striking and resilient in daily use. If further technical details about facet proportions, exact table percentage, or bespoke mounting options are required, our gemology and bench teams can provide additional measurements and recommendations based on the intended piece, to help ensure the sapphire performs well and endures as a piece of daily jewelry.
