23 ct Ceylon Natural Blue Sapphire Crystal from Kataragama Village Around Mining in Sri Lanka

Stone Identity & Quality

This gemstone is a 23 carat Ceylon natural blue sapphire crystal measuring 25 × 11.5 × 10.6 mm. It comes from Kataragama village around mining in Sri Lanka and remains in its unheated natural condition. The crystal is best understood as a collector-quality sapphire specimen with some facet-grade areas, rather than as material mainly intended for standard faceting.

Color & Visual Characteristics

The crystal shows a rich blue body color with strong natural presence. Under light, the blue appears more alive through the crystal body, supported by an excellent natural luster. Its visual appeal comes from the balance of color, shape, and surface character rather than from a polished gemstone appearance.

Internal & External Features

This sapphire crystal shows visible natural growth marks and a well-preserved crystal structure. These external features help confirm its natural formation and add specimen value. Internal zoning and structural character can also be observed, which makes the stone interesting for gem study, collecting, and source-based appreciation.

Cutting & Treatment Potential

This crystal has some facet-grade areas, but the main value of the piece is not in cutting it into a standard gemstone. Because of the natural crystal form and preserved structure, much of its uniqueness is connected to remaining in crystal form. The stone is unheated, and no treatment claim is made beyond its natural untreated condition. Cutting evaluation could be discussed if needed, but specimen value should be considered first.
