22.00 ct Facet Grade Ceylon Blue Sapphire Rough from Elahera, Sri Lanka – Standard Heated Rough with Blue Color Zoning

Stone Identity & Quality

This Ceylon blue sapphire rough weighs 22.00 carats and measures 18 x 14.4 x 9.4 mm. It was sourced from Elahera village around mining in Sri Lanka, an area known for producing natural sapphire rough through traditional gem mining activity. The stone is offered as facet grade rough and is described as standard heated. Its crystal body, size, and visible zoning make it suitable for professional cutting evaluation.

Color & Visual Characteristics

The stone shows a blue body color with visible color zoning, which is a common and important feature in sapphire rough. In uncut material, zoning can appear as concentrated bands or uneven distribution of color, and this becomes a major factor in planning orientation. The body appears attractive and visually promising, with a color presence that may respond differently depending on how the stone is positioned and examined under light.

Internal & External Features

Externally, the rough displays the natural surface character expected in sapphire material, including an uneven crystal form and natural skin. Internally, the presence of blue color zoning is one of the most important visible features. As with most sapphire rough, clarity and internal performance can only be judged more accurately after careful examination. The rough body suggests meaningful potential, but professional assessment remains necessary before determining the most effective cutting direction.

Cutting & Treatment Potential

This is a facet grade rough stone with good cutting potential. Its size and shape give a cutter room to study orientation, zoning placement, depth management, and possible finished shape options. Because the stone is described as standard heated, it should still be approached with technical care rather than assumption. In sapphire rough, the best outcome depends on how well the cutter balances recovery, color retention, and structural stability. This stone may be suitable for buyers looking for rough material with a strong body and visible gemological interest.
