18.53 Ct. Citrine from Brazil

One beautiful transparent 18.53 carat cushion shape yellow citrine awaits a discerning collector, measured precisely at 16.81 by 15.41 by 11.71 millimeters, cut in a mixed brilliant style to balance sparkle and face up size. This stone displays an intense color intensity that reads as a pure, sunny yellow in natural and photographic light, and it has been evaluated at eye level as very very slightly included, a clarity grade that is exceptionally clean for a gem of this scale. The polish has been graded as excellent, which means the facet junctions and mirror like surfaces have been finished to maximize light transmission and surface luster. There is no enhancement of any kind, the color and clarity are wholly natural, and the documented origin is Brazil, a region celebrated for producing fine citrines with excellent hue and stability. At The Natural Gemstone Company we select each gem with an eye toward transparency in grading and provenance, and this citrine is presented with full disclosure so that an educated buyer can assess its intrinsic qualities without uncertainty.

The color characteristics of this citrine are central to its appeal and its value, intense being a rare and desirable level for yellow citrines sourced from Brazil. Citrine derives its yellow to orange hues from trace iron, and when heating has not been applied this indicates a naturally occurring balance of elements within the crystal lattice, which seasoned gemologists and connoisseurs appreciate for both rarity and permanence. An intense yellow that remains uniform across the stone ensures excellent visual impact when set in jewelry, especially when the mixed brilliant cut has been tailored to show a broad, lively table and faceting that returns light as scintillation and dispersion. From a grading perspective, the combination of high color intensity, excellent polish, and a cleanliness level of very very slightly included results in a gem that will appeal to collectors, lapidaries, custom jewelers, and investors who prize stones that combine size, eye appeal, and natural origin.

Clarity and cut are complementary factors that drive a stone toward exceptional performance in wear and display, and in this citrine both aspects are thoughtfully realized. The very very slightly included clarity grade evaluated at eye level means the stone appears virtually clean to an unaided eye, with any inclusions being minor and not detracting from transparency or brilliance. The mixed brilliant cut merges pavilion facets inspired by the brilliant with a more open crown structure to enhance table presence, which is particularly advantageous for larger gemstones that are intended to be set as centerpieces. Excellent polish ensures that light crosses the gem without surface diffusion, preserving sharp facet reflections and lively sparkle, while the substantial depth of 11.71 millimeters provides a sense of three dimensionality and strong light return. From a practical viewpoint citrine rates well for everyday jewelry use, and with reasonable care it maintains its bright yellow hue and structural integrity, making it suitable for rings, pendants, or bespoke pieces that will be enjoyed for decades.

Over the years the natural beauty of this citrine will continue to captivate because of its stable color, excellent cutting and polish, and unenhanced Brazilian origin which together form a trustworthy provenance story. Citrine is known for its resistance to light induced fading when compared to some other colored gemstones, and because this specimen has not been heat treated or irradiated, its color stability is consistent with naturally colored material of the same type. Long term care is straightforward, cleaning with warm soapy water and a soft brush will preserve surface luster, and routine inspections for secure mounting will protect the facets and girdle from accidental damage. For the educated buyer who values documented origin, visible quality, and natural authenticity, The Natural Gemstone Company stands behind this citrine as an example of ethical sourcing, precise grading, and artisanal cutting. This gem will not only be admired for its present visual impact, it will also retain collectibility and desirability for future generations, making it a rewarding acquisition for personal adornment or as a considered addition to a curated gemstone collection.
