4.72 Ct.Tw.Total Carat Weight Yellow Citrine Pair from Brazil

This pair of pear shape yellow citrines from Brazil presents a highly technical expression of cut, color and clarity, ideal for the connoisseur. One stone is 2.30 carats with dimensions 11.59 x 8.04 x 5.05 mm, the matching stone is 2.42 carats with dimensions 11.77 x 7.97 x 5.18 mm. Both are executed in a mixed brilliant cut, combining a brilliant facet arrangement on the crown with a precision stepped and modified pavilion to balance brilliance and face up color. Clarity is graded very very slightly included at eye level, offering clean windows for light transmission, and color intensity is described as intense, producing a saturated, even yellow when viewed face up. Enhancement by controlled heat treatment is disclosed, and excellent polish confirms that facet junctions and surface finish meet strict optical tolerances. The Natural Gemstone Company presents these as a matched pair suitable for fine jewelry settings where consistent tone and symmetry are required.

The sparkling performance of these citrines is a direct result of their fundamental material properties and the cutter s technical choices. As quartz family gems, citrines have a refractive index in the range of approximately 1.544 to 1.553 and low birefringence near 0.009, which means brilliance in quartz derivatives is highly dependent on facet geometry rather than inherent dispersion. By employing a mixed brilliant strategy, the cutter increases the number and orientation of crown facets to maximize return of incident light through optimized crown angles and table proportion, while the modified pavilion geometry is calibrated to promote total internal reflection at the quartz refractive index. The result is high contrast facet play, crisp scintillation and sustained return of the intense yellow tone to the eye. Excellent polish and tight facet junctions minimize surface scatter and internal leakage, preserving specular highlights and allowing the stones to exhibit lively pinpoint flashes and broad light returns together. For technically minded buyers these paired citrines demonstrate meticulous lapidary control over symmetry, facet count and finish, producing a sparkle and color saturation that is numerically efficient and visually distinctive.
