4.36 Ct. Citrine from Brazil

This specimen is a transparent, emerald cut orangish yellow citrine weighing 4.36 carats, a carat weight that positions it within the premium tier for faceted citrines due to the combination of size, color intensity, and eye-clean clarity. The gem measures 10.86 by 8.83 by 6.20 millimeters, resulting in a length to width ratio of approximately 1.23 to 1 and a depth percentage near 63 percent, proportions that are well suited to the classic step-cut geometry. At this 4.36 carat weight the pavilion and crown volumes are sufficient to present sustained color saturation across the broad table without appearing windowed or thin, which is a common issue in lower weight stones. Buyers who prioritize presence and balance in a center stone will recognize that the carat weight here is not merely a numeric value, but an indicator of material that allows for both definitive color expression and substantial wearability in ring and pendant formats.

The cut is a traditional emerald cut with step facets, truncated corners, and a large, open table, executed to emphasize stable, even color rather than scintillation. Step-cut faceting produces broad, planar facet faces that deliver characteristic flash and louvered brilliance, and in this citrine those long steps are proportioned to yield uniform light return while preserving the stone s intense orangish yellow hue. The intense color intensity grade indicates strong saturation and chroma, with orange tones clearly present against a yellow base, producing a warm, vivid appearance that is emphasized by the elongated facet planes of the emerald cut. Because step cuts reduce the number of small facet junctions, the cutting geometry requires precise symmetry and step alignment to avoid uneven color zoning, and this stone demonstrates consistent facet-to-facet alignment that maintains color homogeneity across the table and pavilion.

Clarity is graded eye clean at typical viewing distance, meaning there are no inclusions visible to the unaided eye and the stone presents a clean visual field through the table. Quartz family crystals commonly exhibit subtle growth tubes or microscopic liquid inclusions, but at this grade they do not interfere with the optical presentation or durability of the gem. The polish has been evaluated as excellent, indicating mirror-smooth facet surfaces and crisp facet junctions that contribute to strong light return and clear facet definition. The enhancement is standard heat treatment, applied to stabilize and intensify the citrine tone, a routine and permanent treatment in natural quartz that does not require special care beyond normal jewelry handling. Origin is Brazil, a source known for producing quartz material with attractive tone and good crystal quality, and this provenance is consistent with the observed color and clarity characteristics.

From a gemological and practical perspective this 4.36 carat, 10.86 by 8.83 by 6.20 millimeter emerald cut citrine represents a premium choice for a center stone, offering a substantial visual footprint while retaining the refined optical discipline of a step-cut design. With a refractive index typical of quartz in the range of 1.544 to 1.553 and a Mohs hardness of 7, the stone balances optical performance with durability suitable for everyday wear when set appropriately. Because the emerald cut emphasizes color over dispersion, setting choices should aim to display the table and allow light to pass through the pavilion, with traditional four-prong or bezel settings both viable depending on design priorities; an open back or low-profile setting will maximize perceived saturation for the orangish yellow tone.
