1.69 Ct. Bi Color / Parti Sapphire from Madagascar

One beautiful transparent 1.69 carat heart shape bi color parti sapphire is presented by The Natural Sapphire Company, measuring 6.49 x 7.41 x 5.08 mm, faceted with a mixed brilliant cut, and finished with an excellent polish. This specimen displays medium color intensity with lively bicolor character that shifts through green and yellow tones as light and viewing angle change, and it is graded as very slightly included when evaluated at eye level. The stone is transparent and shows clean faceting symmetry that enhances its scintillation, and it has been heat treated which is a common and stable enhancement that improves color uniformity and overall visual appeal. The origin is Madagascar, a source known for producing a wide range of sapphire colors including parti and bicolor material, and the combination of heart shape and parti coloration makes this a distinctive choice for collectors and designers alike. As an additional detail, the opal type associated with some of our paired pieces is Semi Black Opal, which offers a striking dark body tone that complements parti sapphires in mixed gemstone jewelry.

Compared to more common gemstones such as faceted yellow or blue sapphires, rubies, and diamonds, this bicolor parti sapphire offers a different kind of brilliance. Diamonds have a higher refractive index and stronger dispersion which creates intense white sparkle and fire, whereas sapphires have a subtler, more lustrous brilliance that emphasizes depth of color and internal light play, and the mixed brilliant cut on this heart shape is specifically designed to maximize both scintillation and color contrast. The parti color distribution creates zones of color that catch light in varying ways, producing dynamic flashes that can appear more expressive than uniform color gems, and the very slightly included clarity means that inclusions are minimal and do not interfere with brilliance at normal viewing distances. For an educated buyer this stone is valuable because of its rare bicolor character in a small but well proportioned heart cut, its transparent nature combined with excellent polish, its documented Madagascar origin which is respected for parti sapphire material, and the fact that heat treatment is standard and stable. The Natural Sapphire Company stands behind the description and grading, and this heart shaped 1.69 carat bi color parti sapphire represents a collectible and wearable option that balances aesthetic dynamism with technical quality.
