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

This loose sapphire is a transparent, cushion shape bi color parti sapphire weighing 1.08 carats, with dimensions of 5.75 by 5.08 by 3.31 millimeters. The cutting style is faceted, executed as a mixed brilliant cut, which combines pavilion facets that promote scintillation with crown facets that return color and light through the table. The stone presents a clear transition between cool violet blue tones and a warm peach to champagne area, consistent with medium color intensity across the face of the gem. Clarity is graded as very slightly included when evaluated at eye level, and the stone displays minor natural inclusions that do not detract from its visual appeal or transparency when set. The polish is excellent, producing well defined facet junctions and lively surface reflections. There has been no enhancement to alter color or clarity, and the origin is Ceylon Sri Lanka.

Proportions are balanced for the gem form, with a depth of approximately sixty one percent relative to the average of length and width, a dimension that supports both strong light return and a pleasing face up size for the given carat weight. The mixed brilliant facet arrangement is effective in managing the color zoning that characterizes parti sapphires, allowing different facets to emphasize either the cooler or the warmer areas as the viewing angle changes. The excellent polish and careful facet symmetry reduce light leakage and preserve the stone s natural play of color, while the cushion profile softens the visual outline and complements bezel or prong mounting choices. The very slightly included clarity grade indicates stability for standard jewelry wear, though customary care is recommended to avoid hard knocks that could impact facet edges or corners in open settings.

When composing a custom design, consider accenting the bi color character by pairing complementary gemstones and metals that selectively emphasize either the violet blue or the peach zones. A halo of white diamonds will read as neutral contrast, brightening the sapphire and making the cooler violet areas appear more saturated, while a graduated frame of small warm champagne or cognac diamonds will tether the warmer peach tones and create a cohesive warm palette. For color play, small rose pink spinels or light pink sapphires placed to one side of the main stone will reinforce the peach tones, while tiny violet tanzanite accents can deepen the cooler face up color. Metal choice also influences perception, with platinum or white gold lending a crisp, modern backdrop that favors the blue spectrum, and 18 karat rose gold enhancing the warmth of the peach area and producing an overall softer look. Design considerations include an open prong setting to maximize light entry and color interaction, an east west orientation to showcase the color transition across the face, or a partial bezel for protection at the corners while still permitting significant light return.
