77.90 ct Unheated Ceylon Olive Yellow Zircon Rough from Godakawela, Sri Lanka – Large Facet Grade Rough with Chatoyancy Potential

Stone Identity & Quality

This is a 77.90 ct Ceylon Natural Unheated Olive Yellow Zircon rough measuring 32.5 × 22 × 13.8 mm. The stone is sourced from Godakawela village around mining in Sri Lanka and is offered as a large facet-grade alluvial rough. Its notable size, useful depth, and strong natural shape make it an important piece for buyers who work with rough evaluation and custom cutting planning. This zircon is presented as natural and unheated rough, with two possible cutting directions depending on the structure and visual behavior of the material.

Color & Visual Characteristics

The stone shows an olive yellow body color with a natural soft glow in rough form. In lighter areas, the color appears bright and open, while thicker areas show a deeper olive yellow concentration. The overall visual character is attractive for a large zircon rough, especially because the color is visible through the body even before cutting. The material also shows visible chatoyancy potential, which adds interest beyond normal faceting possibilities.

Internal & External Features

This zircon rough has a natural alluvial surface with the frosted skin, worn edges, and surface texture expected from river-related rough material. The external form appears very suitable for pre-cutting study because the stone has both width and depth. Based on the provided information, the rough is valued mainly for its cutting potential and for the additional possibility of exploring chatoyancy in cabochon form. As with all rough stones, the internal structure, clean areas, and surface removal requirements should be evaluated carefully before cutting.

Cutting, Specimen, or Treatment Potential

This stone offers two main directions. The first is faceting, where the cutter can study orientation and proportions to create a large finished zircon. The second is cabochon cutting, where the visible chatoyancy potential can be tested to see whether a cat’s-eye effect can be developed. Because of its size and rough shape, this zircon gives flexibility in planning. The final decision should depend on internal structure, color direction, surface removal, yield, and the strength of the chatoyancy potential. No final cutting result should be guaranteed before proper physical examination.
