1.42 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.42 carat round shape blue sapphire with dimensions of 6.57 by 6.50 by 4.42 millimeters is presented by The Natural Sapphire Company, faceted to a mixed brilliant cut that balances scintillation and depth, exhibiting vivid color intensity and an excellent polish. This gem is eye clean when evaluated at eye level, meaning that under normal visual inspection no inclusions detract from its clarity or visual appeal. The stone has been heat treated, a widely accepted and stable enhancement in the sapphire market, applied to optimize its natural color and overall appearance. Origin is Ceylon Sri Lanka, a classic source known throughout the gem trade for producing sapphires with lively, saturated blues, and the combination of weight, dimensions, cut, clarity and color in this example results in a gemstone that reads as both visually striking and well proportioned for fine jewelry settings.

From a gemological perspective this sapphire presents attributes that an educated buyer will immediately appreciate, beginning with color. Vivid intensity indicates a strong saturation and a pleasing medium to deep tone that reads richly in both natural and artificial light, characteristics that are particularly desirable in Ceylon material. The round mixed brilliant cut is designed to marry the brilliance associated with standard brilliant faceting to pavilion facets that encourage depth of color in a colored gemstone, producing a lively play of light across the crown while preserving color saturation through the body of the gem. The excellent polish means facet junctions are crisp and surfaces are smooth, supporting maximum light return and visual performance. The eye clean clarity grade confirms that the stone communicates well to the unaided observer, conserving value because minor inclusions that are positioned or sized so as to be invisible to the eye do not reduce face up brilliance or desirability.

Regarding enhancement and disclosure, heat treatment is declared because transparency about treatments is an essential part of the buying process and part of how The Natural Sapphire Company builds trust. Heat treatment is an established practice in the sapphire trade, applied under controlled conditions to enhance color evenly and permanently, and it does not degrade the inherent durability of corundum, which rates nine on the Mohs hardness scale, making sapphires suitable for daily wear in rings, pendants and other jewelry. For an informed purchaser, the presence of heat treatment is not a negative in and of itself, rather it is a neutral piece of technical information that should be weighed along with origin, cut quality, clarity and color when determining market value and suitability for a particular design or investment objective. The dimensions of 6.57 by 6.50 by 4.42 millimeters and the 1.42 carat weight place this gem in a size range that is versatile for classic solitaire settings, three stone rings and bespoke designs that emphasize color and brilliance.

Ethical sourcing and traceability are central to how The Natural Sapphire Company presents this sapphire to customers who prioritize conscientious purchasing. This gem originates in Ceylon Sri Lanka, and it is sourced through supply chains that prioritize documented provenance and responsible practices, with partners who follow local regulations and work to support fair labor practices and community benefits. We emphasize practical traceability, careful selection at origin, and cooperation with local miners and cutters to ensure that the stone you receive is both authentic and sourced in a way that seeks to minimize negative social and environmental impacts. For the mindful buyer this sapphire represents an opportunity to own a piece of natural history that is disclosed and documented, a natural corundum with a known origin, a known enhancement history, and a transparent chain of custody, allowing the purchaser to make an informed choice that aligns with ethical values. Paired with its technical merits, including mixed brilliant faceting, vivid color intensity, eye clean clarity and excellent polish, this sapphire is an ideal candidate for a conscious collection where beauty and responsible sourcing matter equally.
