20.70 ct Ceylon Natural Unheated Yellowish-Green Chrysoberyl Crystal from Embilipitiya, Sri Lanka

Stone Identity & Quality

This gemstone is a 20.70 ct Ceylon natural chrysoberyl crystal measuring 18.8 × 15.6 × 5.9 mm. It was sourced from Embilipitiya village around mining in Sri Lanka and remains in its natural unheated condition.

The stone is presented as a unique chrysoberyl crystal specimen rather than standard facet-grade rough. Its main qualities are the yellowish-green color, preserved natural form, broad crystal face, naturally occurring marks, and unusual overall appearance.

The crystal is suitable for collectors, natural gemstone displays, gemological observation, mineral study, and buyers who appreciate original formation features.

Color & Visual Characteristics

The crystal shows a natural yellowish-green body color with areas that may appear more yellow or more green depending on the lighting direction, background, and thickness of the material.

Under direct light, the stone displays a vitreous surface response and a brighter greenish-yellow appearance. In softer light, the color can look warmer and more olive-yellow. This visual variation is influenced by the natural crystal body, surface texture, and internal structure.

The wide crystal face provides a strong surface view, making the formation marks and color distribution especially noticeable.

Internal & External Features

One of the most important characteristics of this crystal is its naturally occurring surface pattern. The broad face shows intersecting lines, irregular grooves, layered marks, and natural structural features formed during crystal growth or later geological movement.

The stone also shows natural edge wear, uneven areas, internal features, and minor fractures consistent with an uncut natural crystal specimen. These marks are not presented as cutting defects alone; they are part of the crystal’s geological history and contribute to its specimen identity.

Because the stone remains unpolished, its natural surface should be appreciated differently from the finish expected in a faceted gemstone.

Cutting, Specimen, or Treatment Potential

This chrysoberyl is mainly valued as a natural crystal specimen, not as standard facet-grade rough.

A cutter could examine individual areas for possible polishing, windowing, carving, or a special creative project. However, the stone’s relatively broad and shallow form, natural marks, and preserved crystal face may limit conventional faceting options.

Cutting could remove the unusual surface structure that gives the piece much of its natural character. For that reason, preservation as a specimen should be considered before any lapidary decision.

No finished weight, clarity, cutting yield, or final design can be guaranteed without detailed professional examination. The crystal is presented in its natural unheated condition.
