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

This item is a transparent 2.97 carat emerald cut bi color parti sapphire originating from Ceylon Sri Lanka, with dimensions of 9.13 x 6.04 x 5.05 mm. The stone is faceted in a classic emerald cut, exhibiting step facets that produce broad, linear flashes and an orderly interplay of light and color. Clarity is graded as very slightly included when evaluated at eye level, and the polish is excellent, producing clean facet junctions and strong light return. Color intensity is light, with distinct bi color zoning that reads as soft blue and pale yellow to green depending on orientation and lighting. There has been no enhancement to alter the stone, which preserves its natural character and origin, and the sapphire benefits from the inherent durability of corundum making it suitable for everyday wear when set appropriately.

For a custom piece the emerald cut profile and subtle parti tones favor designs that either emphasize the stone as the focal element or harmonize its dual hues with complementary accents. A minimal prong or semi bezel setting held east west will accentuate the horizontal color banding and emphasize the elongated silhouette, while a four or six prong vertical mount will showcase the step facets. Metal choice will influence perceived color, with 18 karat white gold or platinum amplifying the blue aspects, and 18 karat yellow gold or warm rose gold enhancing the yellow green areas. Accent stones can be used to balance or contrast the parti effect, for example small round brilliant diamonds will provide neutral scintillation and increase perceived brightness, paired tapered baguettes in white or blue sapphire will extend the emerald cut geometry, and petite yellow or green sapphires or tsavorites will pick up and intensify the warm zone. A three stone arrangement with matching side sapphires or a halo of mixed white melee and colored melee can create a tailored balance of color and brilliance. The Natural Sapphire Company can assist with precise dimensions for setting tolerances and sourcing matched accents, ensuring the finished design preserves the stone integrity and presents the bi color character in a considered and enduring manner.
