Natural Ceylon Sapphire Twin Crystal – 56.21 ct Unheated Crystal Specimen from Kolonna, Sri Lanka

Stone Identity & Quality

This is a natural Ceylon sapphire twin crystal weighing 56.21 ct and measuring 41 × 16.8 × 12.6 mm. It was sourced from Kolonna village around mining in Sri Lanka and remains in natural unheated condition. This material is not classified as facet grade rough. It is better suited for crystal specimen purpose, collection, mineral study, display, or buyers who appreciate natural sapphire crystal formation.

Color & Visual Characteristics

The crystal shows a lustrous light blue color body with natural sapphire crystal appearance. Under light, the surface displays reflective areas, internal texture, and natural growth direction. The body is not presented as clean faceting material, but as a natural sapphire crystal with visible geological character. Its visual appeal comes from the crystal structure, twin formation, and natural surface features rather than potential finished gemstone yield.

Internal & External Features

This sapphire shows naturally occurred growth marks, surface texture, and crystal-related features that are normal in natural sapphire specimens. The twin crystal structure makes the piece more interesting from a geological and collector perspective. Because the stone is non-facet grade, these features should not be viewed as cutting defects only, but as part of the natural formation story of the crystal.

Cutting & Treatment Potential

This sapphire is currently unheated and natural. It is not recommended as a primary faceting rough because it is non-facet grade material. Any possible small usable area would require careful expert inspection, but the main purpose of this piece is crystal collection, study, or display. No cutting yield, final color, or finished gemstone result should be assumed from this type of crystal specimen.
