1.19 Ct. Greenish Yellow Sapphire from Ceylon (Sri Lanka)

This 1.19 carat Ceylon origin sapphire presents as a transparent, greenish yellow cushion, with dimensions of 7.28 x 5.11 x 3.55 millimeters, and a vivid, intense color intensity. The stone is heat treated, a standard enhancement for Ceylon sapphires that stabilizes and deepens hue while preserving the mineral integrity of corundum. Clarity is graded as very very slightly included, evaluated at eye level, which means the crystal is effectively eye clean and retains exceptional transparency under normal viewing conditions. The cutting style is a mixed brilliant cut, and the polish is graded excellent, a combination that The Natural Sapphire Company selects to maximize both color saturation and optical performance. The cushion outline and balanced proportions make this gem a versatile center stone for precision settings, while the provenance from Sri Lanka underscores a geological heritage known for well colored, highly saturated sapphires.

The mixed brilliant cut employed in this sapphire intentionally combines a faceted brilliant crown with a more structured pavilion, creating a synergy between dispersion and light return. The crown facets are configured to act as an efficient light collector, dispersing incoming white light into spectral flashes and directing it towards the pavilion. The pavilion facets, cut with an emphasis on controlled angles and facet termination, act as a reflective engine, returning light back through the crown in a way that reinforces apparent color and scintillation. With a measured depth of 3.55 millimeters, representing approximately 57 percent of the average of length and width, the proportions fall into an optimal range for balancing brilliance and color depth. A shallower pavilion might sacrifice color, while a deeper pavilion could mute face up brightness, so this proportioning speaks to intentional cutter decisions that favor vivid greenish yellow saturation while maintaining lively return of light.

Optically, sapphires have a relatively high refractive index, which aids in strong internal reflection when facets are properly angled, and this sapphire leverages that physical property through precise facet geometry. The mixed brilliant arrangement increases the number of small, high contrast facets near the crown, which produces crisp scintillation under movement, while the larger pavilion facets create areas of sustained color and contrast that make the greenish yellow appear intense without overpowering brilliance. Excellent polish eliminates micro abrasions that would otherwise scatter light and reduce contrast, so the facet planes act as clean mirrors that transmit and reflect light efficiently. The very very slightly included clarity grade means that internal features are minor and generally aligned so as not to interrupt the main light paths, allowing the cutter to place facets that either conceal inclusions or position them away from the table for minimum visibility, preserving the gem s optical integrity.

From a craftsmanship and practical perspective this cushion mixed brilliant sapphire is engineered for settings that showcase both color and movement, and The Natural Sapphire Company offers expert mounting recommendations to complement the stone s optical behavior. A modest table with slightly elevated crown will continue to favor face up brilliance and scintillation, while a bezel or low profile prong setting can protect the pavilion and maintain the stone s proportion to the ring plane. Heat treatment performed on this stone is stable under normal wear and routine jewelry maintenance, however professional cleaning methods are recommended to avoid ultrasonic or steam exposure without prior consultation. For the connoisseur who values technical execution, this sapphire demonstrates deliberate facet design, balanced proportions, and a finish that together accentuate corundum s high refractive index and inherent color properties, making it an exemplary choice for someone seeking a finely crafted, intensely colored greenish yellow sapphire from a respected source.
