0.70 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent yellow sapphire presents as a precisely cut emerald shape, weighing 0.70 carat, with dimensions of 5.13 x 4.57 x 3.09 mm, and an excellent polish that speaks to careful lapidary work. The cut is an emerald style, with stepped facets that produce a measured, architectural brightness and a balanced table proportion, making the gem suitable for a variety of classic and contemporary settings. Clarity is graded as very very slightly included when evaluated at eye level, which means that the stone appears clean to the unaided eye while retaining the natural character of a mined corundum. Color intensity is described as faint, offering a delicate yellow presence that reads as refined and versatile, able to complement both warm and cool metal choices. The gem is natural and untreated, with no enhancement reported, and its origin is Ceylon Sri Lanka, a source long associated with fine, naturally colored sapphires.

From a gemological perspective this sapphire combines attributes that favor long term preservation and continued desirability. As corundum, sapphire ranks highly on the Mohs hardness scale, providing substantial resistance to abrasion and daily wear, when set with appropriate protection. The emerald cut emphasizes clarity rather than dispersing color, which benefits a faintly colored stone by delivering clear, even tones and by allowing the eye to appreciate the internal structure and polish quality. The grade of very very slightly included indicates that inclusions are minimal and not visually intrusive, which supports the stone remaining attractive and serviceable through handling and routine cleaning. The excellent polish enhances surface durability and optical performance, reducing the likelihood of surface wear that can soften facet junctions and diminish sparkle over decades of use.

The provenance as a Ceylon sapphire and the absence of enhancement contribute directly to the piece becoming a true generational heirloom. Ceylon sapphires carry a distinct historical cachet in the market, recognized by collectors and gem connoisseurs, and an untreated stone preserves the natural story of formation and origin. Untreated sapphires are less common than treated material, and that rarity underpins both sentimental and potential investment value over time. Careful documentation of origin, weight, dimensions, and clarity provides future custodians with the essential facts needed to verify authenticity and to appreciate the stone in its historical context. The combination of durability, classic emerald cut, clear appearance, and natural provenance creates a gem that can be handed down, reset, or repurposed with confidence, while retaining both its aesthetic appeal and its intrinsic identity.

When fashioned into a setting the sapphire can serve as a centrepiece that endures stylistically and physically. The emerald cut lends itself to settings that balance protection with visibility, for example a four prong or a raised bezel that preserves the clean lines of the cut while guarding the girdle from impact. Because the color is faint and subtle, the gem adapts well to yellow, rose, or white metals, and it can be paired with accent stones for a family piece that feels timeless rather than tied to a single trend. The Natural Sapphire Company can provide detailed information on the stone and assist in choosing a mounting that emphasizes longevity and wearability, ensuring that the setting complements both the dimensions of 5.13 x 4.57 x 3.09 mm and the 0.70 carat weight. Routine maintenance recommendations are straightforward, cleaning with mild soap, a soft brush, and warm water, periodic professional inspections to confirm secure settings, and mindful storage to avoid hard contact with other gems. Taken together these factors support the role of this Ceylon yellow sapphire as a viable, meaningful heirloom, ready to be preserved and appreciated by successive generations.
