6.64 Ct. Greenish Yellow (Lemon Quartz) Quartz from Madagascar

This description concerns a single transparent lemon quartz, cushion shape, weighing 6.64 carats, with dimensions 14.77 by 9.48 by 7.32 millimeters. The cutting style is faceted, executed in a mixed brilliant cut that combines multiple facet types to balance brilliance and color. The stone exhibits a greenish yellow hue with intense color intensity, and its clarity is graded eye clean when evaluated at eye level. The polish is excellent, producing refined facet junctions and a smooth surface finish. No enhancement has been applied to this gem, and the specimen is of Madagascar origin, a source known for yielding fine natural quartz specimens. These core specifications define the material identity and physical presence of the gem, and they provide the factual foundation for considerations relating to design, setting, and long term stewardship.

The cutting and finishing of this lemon quartz speak to considered craftsmanship. The mixed brilliant faceting integrates pavilion and crown arrangements that are designed to return light efficiently while maintaining color saturation, a particularly important balance in stones of yellow to greenish yellow tone. The cushion outline offers rounded corners with a gentle rectangular to square proportion, a silhouette that enhances perceived surface area and complements a range of mounting styles. At the stated dimensions and carat weight, the pavilion depth and table proportions have been optimized to preserve the stone volume, yielding a visually substantial presence without compromising optical performance. The eye clean clarity grade indicates that under normal visual inspection there are no inclusions that detract from the transparency or light performance of the stone, and the excellent polish contributes to crisp facet play and reliable light return across viewing angles.

Owning this quartz represents an investment in beauty and craftsmanship rather than a speculative financial instrument. The stone’s unenhanced status is a material attribute that appeals to collectors and designers who prioritize natural state and provenance, because the absence of treatments preserves original color distribution and internal features. The intense natural color in this size and clarity category is less commonly encountered, which enhances its suitability for bespoke jewelry projects where color consistency and depth are priorities. From a craftsmanship perspective, the decision to cut the gem in a mixed brilliant cushion format reflects an intent to maximize both scintillation and color presentation, attributes that do not arise by accident but by informed lapidary planning and execution. The origin from Madagascar adds a layer of traceable provenance, allowing the owner or maker to document the supply chain and to attribute the piece to a recognized locality for natural quartz production.

Practical considerations for integration into jewelry and for long term care follow from the stone’s material properties and finishing. Quartz registers at Mohs hardness 7, which affords good resistance to everyday wear, while still benefiting from protective settings for rings and other items subject to impact. Settings that partially bezel the girdle or that use secure prongs with a modest bezel lip will reduce exposure of the pavilion facets to knocks, while open gallery designs can be used to enhance light entry for maximum brilliance. The dimensions and rectangular cushion profile make this gem suitable for a variety of design orientations, including vertical or horizontal placements in pendants or statement rings, and its size allows it to function as a primary center stone in medium to large scale jewelry. Cleaning may be undertaken with warm water, mild detergent, and a soft brush, followed by thorough rinsing and drying, avoiding harsh chemicals and ultrasonic methods if the setting or any ancillary materials are not suitable. Documentation of the gem’s attributes, including carat weight, measurements, cut style, clarity grade, color intensity, polish, enhancement status, and origin, is provided to support authenticity and to inform future appraisals.
