2.30 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

This 2.30 carat, round shaped bi color parti sapphire presents a precise set of gemological attributes that will appeal to technically minded buyers, the stone measures 7.24 by 7.28 by 5.43 millimeters, its transparency and intense color intensity are immediately apparent face up, the cutting style is faceted with a mixed brilliant ideal that combines a brilliant facet arrangement on the crown with a more controlled pavilion geometry to balance scintillation and color. The mixed brilliant execution in a round outline allows the cutter to preserve weight while opening the table to reveal the parti color distribution, the stone is visually eye clean when evaluated at eye level which indicates an absence of inclusions that would impede light transmission in practical viewing, the polish is graded excellent reflecting meticulous lap work and final finishing to minimize light leakage at facet junctions, the girdle is proportioned to support secure mounting without excessive removal of material, the overall depth of 5.43 millimeters relative to the 7.26 millimeter average diameter produces a depth proportion of approximately 74.8 percent, this relatively deep profile supports saturation of the parti hues while the mixed brilliant facet plan controls brilliance and face up presence.

From a faceting and optical engineering perspective, the mixed brilliant cut used here is deliberate, the crown receives smaller, well angled star and bezel facets to create multiple light return zones, the pavilion facets are organized to enhance internal reflection and to modulate the stone s color display across the table and crown, this is particularly useful in bi color or parti material where the objective is to present distinct color areas without allowing excessive light leakage between zones, the cutter s approach balances pavilion angle and crown angle to favor color saturation in the body while preserving a lively scintillation when the stone moves, the result is a gem that exhibits dynamic flashes of light and well defined color zones, the execution of facet junctions and symmetry influences the visual blending between the two dominant hues, the excellent polish minimizes surface diffusion of light which keeps the color boundaries crisp and the brilliance lively.

The gemological context for this sapphire is important for both connoisseurs and investors, the origin from Ceylon, Sri Lanka is a recognized source for sapphires that display bright, lively tones and a certain velvety brilliance that collectors prize, heat treatment has been applied, this is a standard, stable and well documented enhancement in the trade that optimizes color and clarity while preserving the structural integrity of corundum, disclosure of heat treatment is in line with responsible market practices and The Natural Sapphire Company provides transparent information on enhancements, heat treated sapphires remain highly desirable and liquid in the market, the treatment does moderate the relative price premium compared with comparable untreated material, however, the combination of notable size at 2.30 carats, eye clean clarity, and strong particulate color zoning maintains strong market appeal.
