1.40 ct Certified Heated Ceylon Vivid Yellow Sapphire – Pear Cut

This 1.40 ct natural vivid yellow sapphire comes from Ratnapura, Sri Lanka, and measures 8.57 × 5.64 × 3.87 mm. Finished as a pear-shaped faceted gemstone, it shows a transparent body, bright yellow to golden reflections, and a lively appearance under changing light. Its accompanying certification reports an indication of heating.

Yellow sapphire is a variety of corundum (Al₂O₃). Its characteristic coloration is commonly associated with iron-related color mechanisms. Corundum has a Mohs hardness of 9, making it suitable for many fine jewelry applications, provided its individual inclusions and setting requirements are considered.

A notable feature of this sapphire is a localized feather inclusion near the pavilion. Microscopic photographs show a central stress point within this area and a curved, nearly semicircular feature consistent with a discoid tension fracture. Under oblique illumination, the fracture exhibits rainbow-like iridescence, possibly caused by thin-film interference. The appearance of this feature does not, by itself, establish when the fracture developed.

The stone appears relatively clear outside this localized inclusion. Its position and possible surface connection should be checked before mounting. The pear outline offers possibilities for pendants, collector settings, and carefully designed rings; the pointed tip and inclusion area deserve appropriate protection.

Ratnapura is a major source region in Sri Lanka’s longstanding gemstone trade. This sapphire is professionally supplied by Liyanage Lapidary for gem dealers, jewelers, collectors, and custom jewelry manufacturers.
