13.05 Ct. Orangish Yellow Citrine from Ceylon (Sri Lanka)

This 13.05 carat marquise citrine presents a precise combination of weight, proportions, and color that will appeal to technically minded collectors and designers. The stone measures 19.00 by 14.19 by 9.07 mm, producing a length to width ratio of approximately 1.34 which classifies it as a broad marquise profile rather than an elongated form. This proportion concentrates color face up and provides a strong visual presence on the finger or in a pendant. The cutting style is faceted with a mixed brilliant approach, where the crown is configured with a modified brilliant facet arrangement to maximize return of white light and the pavilion facets are calibrated to reinforce internal reflections and scintillation. The table facet is balanced with the surrounding star and bezel facets to promote even dispersion, and the facet junctions demonstrate well executed symmetry which minimizes light leakage along the central axis. The excellent polish yields crisp facet planes and razor sharp facet lines, producing high contrast between flash and dark areas that enhances perceived brilliance.

Color and clarity are meticulously evaluated, with this citrine graded as intense in color intensity and eye clean when assessed at typical viewing distance. The hue reads as orangish yellow, a saturated warm tone that sits between classic golden citrine and deeper imperial ranges, and the color distribution is notably uniform across the table and girdle planes with minimal zoning. The eye clean clarity grade indicates absence of any inclusions visible to the unaided eye, which allows uninterrupted light travel through the pavilion and contributes to lively scintillation and consistent body color. From a gemological handling perspective the gem has undergone standard heat treatment which is an established enhancement technique for citrine and is stable under normal wear conditions. The heat treatment has been applied judiciously to intensify the orangish yellow saturation without compromising crystal integrity. Origin is recorded as Ceylon Sri Lanka which provides provenance and aligns with a tradition of skilled lapidary work in the region.

Craftsmanship specifics make this piece suitable for a lifetime of wear and eventual transmission to the next generation. The cutter controlled facet angles to balance brilliance and durability, avoiding excessively shallow pavilion angles that can increase vulnerability to impact. The girdle thickness is well proportioned to facilitate secure setting, and the culet is minimized to prevent stress concentration. With a Mohs hardness of 7 the quartz family material is resistant to daily wear, and with the excellent polish the surface will maintain luster with normal care. Recommended settings for long term wear include low profile bezel or well engineered prong configurations that protect the pointed ends typical of the marquise shape. Periodic professional cleaning and inspection of the setting will preserve both the mount and the stone, and The Natural Gemstone Company can provide documentation detailing the cut parameters, color assessment, and treatment disclosure to accompany the gem for provenance and insurance purposes.

As a generational heirloom this 13.05 carat marquise citrine is designed to deliver lasting aesthetic and sentimental value. Its combination of substantial carat weight, controlled proportions, and stable color treatment create an object that is both wearable and collectible. The broad marquise profile offers a commanding visual identity that can adapt to different design aesthetics across eras, allowing the piece to be reset as styles evolve while retaining the original stone. Provenance from Ceylon Sri Lanka and full documentation from The Natural Gemstone Company enhance market traceability and authenticity, which are important attributes for legacy pieces. Properly set and maintained this citrine will retain its optical qualities and physical integrity, making it an ideal candidate for a family heirloom to be passed down, appreciated for both its technical excellence and its capacity to carry stories across generations.
