4.35 Ct. Grey Star Sapphire from Ceylon (Sri Lanka)

This natural star sapphire is a translucent cabochon cut specimen weighing 4.35 carats, presented in an oval outline with measured dimensions of 10.42 x 7.20 x 6.37 millimeters. The bodycolor is a subtle grey with light color intensity, allowing the internal light scattering to remain the dominant visual characteristic. The stone displays a pronounced asterism, with a centered, six ray star that is visible under directional lighting. Clarity is graded as very slightly included when evaluated at eye level, indicating the presence of internal features that do not materially detract from the overall appearance or the formation of the star, and the surface has been given an excellent polish to maximize the interaction between light and the cabochon dome.

Optical and gemological attributes of this piece are consistent with a natural corundum star sapphire from Ceylon, Sri Lanka, and no enhancement has been applied to alter color or surface appearance. The star effect arises from oriented needle like inclusions that reflect light in asterism, and the symmetry of the star across the dome demonstrates careful cutting to align the cabochon axis with the crystal orientation. Translucency is sufficient to allow an even, soft display of the star, while the light grey tone creates a restrained, classical aesthetic that emphasizes the optical phenomenon rather than vibrant bodycolor. The excellent polish contributes to the sharpness and contrast of the star under strong light, and the cabochon proportions preserve depth and durability for typical jewelry mounting.

Practical considerations for the gem in use and care are straightforward, given the inherent hardness and stability of corundum combined with the cabochon form. The shape and asterism make this sapphire well suited to bezel set rings, pendants, or cufflinks where the dome can be exposed to controlled lighting to reveal the star, and a secure setting will protect the girdle and pavilion from impact. Routine cleaning with warm soapy water and a soft brush is appropriate, and care should be taken with sudden thermal or mechanical shock when any surface reaching features are present. The Natural Sapphire Company is committed to transparent sourcing and description, and this stone is offered with its declared Ceylon origin and no enhancements, supported by our internal evaluation notes on weight, measurements, clarity at eye level, cut style, color intensity, polish quality, and optical phenomena.
