Exceptional natural sapphire of 5.70 carats, officially certified as Parti-Colored Sapphire (multicolor sapphire), one of the most exclusive, cutting-edge, and sought-after varieties in high gemology.
The gem stands out for its captivating natural color zoning, showing hues ranging from lime green and bright yellow to deep olive tones. Its pear shape features an elegant combination of a brilliant crown (facets in rhomboid/triangle on top to yield flashes and fire) and a stepped pavilion (facets parallel below) to highlight its crystal clarity and color depth.
* Highlights:
Authenticity and Guarantee: Accompanied by its official gemological certificate issued by ICA GEMLAB.
Unique Piece: As a natural multicolor gemstone, no two sapphires are alike in nature.
Excellent Commercial Size: With nearly 1.1 cm in length and over 5.7 carats, it is perfect as a centerpiece stone for an exclusive design ring, a high-end pendant, or a private collection.
Characteristics in your Sapphire:
Cut: Mixed (Modified Brilliant / Step): Your stone combines a brilliant crown (facets in rhombus/triangle on top to give flashes and fire) with a stepped pavilion (facets parallel below).
“Mirror Hall” Effect: The stepped section creates a clean, elegant reflection with great geometric depth.
Highlights Color and Clarity: Unlike a pure brilliant cut, the stepped cut does not hide the gem’s interior, but shows with total clarity its transparency and the multicolor zoning (green, yellow, and olive).
Multicolor sapphires display irreproducible natural color zoning, which makes this stone truly unique and can reach a value of $4,500 USD / €4,200.
