4.21 Ct. Sinhalite from Ceylon (Sri Lanka)

This natural sinhalite presents as a transparent, golden yellow cushion weighing 4.21 carats, with precise dimensions of 10.62 by 8.51 by 6.59 millimeters. The gem has been cut in a mixed brilliant style, a choice that marries the depth and presence of a modified step outline with the scintillation and light return of brilliant faceting, resulting in an engaging and nuanced face up appearance. At eye level the stone is graded as very very slightly included, a clarity characteristic that preserves visual purity while confirming natural origin, and the piece displays a medium light color intensity that reads as warm and elegant rather than overpowering. The surface finish is described as excellent polish, and there has been no enhancement applied to alter color or clarity, a condition that enhances its appeal to collectors and connoisseurs who prioritize untreated material. The sinhalite originates from Ceylon Sri Lanka, a provenance that is historically associated with fine gem quality and adds a layer of documented geographic interest to its intrinsic attributes.

Optical behavior and cutting finesse are central to the appeal of this gemstone, and the mixed brilliant treatment has been executed to accentuate both brilliance and internal fire. The cushion outline provides generous table and crown interplay, enabling strong light performance across the pavilion facets and producing a lively pattern of flashes when the stone moves. Color zoning is minimal, and the medium light intensity is evenly distributed, permitting the golden yellow tone to remain consistent from one viewing angle to another while revealing subtle nuances under direct illumination. The very very slightly included clarity grade reflects minute internal features that do not detract from the gem when observed without magnification, and these features can serve as markers of natural origin for those who value traceable authenticity. The excellent polish contributes to crisp facet junctions and clean reflections, and the overall symmetry supports accurate light architecture, enhancing both brilliance and scintillation. As an untreated gem from Sri Lanka, this sinhalite combines pleasing visual dynamics with collector oriented credentials, making it an excellent candidate for both bespoke jewelry projects and collection level holdings.

This sinhalite makes a striking and thoughtful gift for someone who appreciates rarity and refined understatement, its golden yellow hue conveying warmth and presence without relying on excessive saturation. In a solitaire ring setting the stone will read as a confident statement, its cushion dimensions offering a substantial table area for optical display, and when mounted in a halo or three stone composition the mixed brilliant faceting will interact attractively with accent stones to produce complementary sparkle. The stone is equally suitable for pendant settings where its size and color will draw attention close to the face, and a custom setting will allow the design to balance protection and light exposure to preserve both durability and performance. Care recommendations include gentle cleaning with mild soap and water, and handling with routine attention to avoid abrasive contact or hard knocks, and for specific cleaning methods or setting options professional guidance is advised. The Natural Gemstone Company is available to provide further information regarding this sinhalite, including high resolution imagery and consultation on design and setting, and clients who seek an unenhanced, well cut gem with verifiable origin will find this example a compelling option that combines aesthetic refinement with clear, transparent specification.
