7.50 Ct. Greenish Yellow (Lemon Quartz) Quartz from Brazil

This transparent round greenish yellow lemon quartz weighs 7.50 carat and measures 12.83 by 12.91 by 8.71 millimeters, cut in a faceted mixed brilliant configuration with excellent polish, no enhancement, and Brazilian origin. The cutter has employed a mixed brilliant strategy with a brilliant style crown and a modified step pavilion, producing crisp facet junctions and controlled light return, while the deeper pavilion profile yields a measured depth approximately sixty eight percent that increases apparent internal light play without compromising the stone s transparency. Clarity is graded as very slightly included at eye level, indicating sparse, fine inclusions that do not materially interrupt the stone s window or its face up performance, and light color intensity allows the stone to read as pale lemon with a discernible green inflection when viewed in transmitted lighting. The optical behavior aligns with quartz family properties, including low dispersion and a moderate refractive index, so the cutting emphasis has been placed on facet angles and table size to maximize scintillation and to reinforce the subtler greenish yellow hue.

In direct chromatic comparison the tone and hue of this specimen differ systematically from several famous source varieties, which helps place its aesthetic within a collector s palette. Relative to Sri Lanka yellow sapphire examples the quartz is appreciably paler and cooler, as Sri Lankan sapphires typically present a warmer, more saturated golden yellow hue and higher refractive brilliance, whereas this lemon quartz carries a softer, more pastel green tint. Compared to Brazilian citrine, which often displays stronger honey to amber tones, this stone is greener and lighter in tone, reflecting its Brazilian pegmatitic context rather than heated quartz signatures. In relation to San Carlos Arizona peridot the peridot will show a denser olive green saturation and greater chroma, making the quartz s greenish yellow appear more delicate and restrained by contrast. Against Colombian emeralds and Zambian emeralds the difference is pronounced, emeralds being markedly deeper and more saturated green, while the lemon quartz is valued for its clarity and pale springlike hue rather than for saturation. The Natural Gemstone Company presents this gem as an example of technical cutting finesse applied to a light greenish yellow quartz, a stone that will appeal to connoisseurs who prioritize faceting precision, natural color, and unenhanced provenance.
