12.70 ct Ceylon Natural Unheated White Sapphire Rough Parcel – 7 Facet Grade Stones from Bibilegama, Sri Lanka

Stone Identity & Quality

This parcel contains 7 Facet Grade Ceylon Natural Unheated White Sapphire rough stones with a combined weight of 12.70 ct. Individual stones range from approximately 2.45 ct to 1.10 ct.

The parcel was sourced from Bibilegama village around mining in Sri Lanka and is presented in natural, unheated condition.

Most of the parcel shows white to near-colorless sapphire character, while one stone carries a very subtle light yellow hue. Because these are individual natural rough stones rather than calibrated material, each piece has its own proportions, internal characteristics, and cutting possibilities.

Color & Visual Characteristics

The dominant visual character of this parcel is white to near-colorless sapphire.

White sapphire is the trade description commonly used for colorless or near-colorless corundum. In this parcel, most pieces show very little obvious body color, while one stone displays a slight yellow influence.

Under direct light, the rough pieces can show different levels of brightness and transparency depending on thickness, orientation, surface texture, and internal structure.

The final face-up appearance after cutting cannot be determined only from the rough exterior. Correct orientation and facet angles will be important for achieving good brilliance.

Internal & External Features

Each stone shows natural rough surface characteristics consistent with its unpolished condition.

The pieces should be inspected individually for:

transparent usable areas

internal inclusions

surface-reaching features

depth

natural shape

possible orientation

expected cutting yield

Because sapphire rough can appear different when viewed from different directions, evaluation under transmitted and direct light is useful before preforming.

No specific clarity grade is being assigned to the finished potential of these stones before cutting.

Cutting Potential

These stones are presented as facet-grade rough, giving them practical potential for custom faceting after professional evaluation.

White sapphire requires careful cutting because brilliance is particularly dependent on proportion and light return. Without strong body color to visually compensate for weak cutting, poor angles may create visible windows or a lifeless appearance.

For this reason, the cutter should evaluate each stone for:

crown and pavilion depth

orientation

clean usable area

natural outline

possible finished shape

weight retention

light performance

Depending on each individual rough, possible finished designs may include oval, cushion, round, pear, emerald-style, or custom cuts. However, no specific finished weight, clarity, or result should be guaranteed before cutting.

Custom cutting and certification can be discussed if suitable.

Source & Ethical Position

Danushka Gems & Minings works with gemstone-producing areas throughout Sri Lanka and focuses on showing rough material with practical, transparent information.

This parcel comes from Bibilegama village around mining in Sri Lanka, maintaining a clear source connection rather than presenting the stones simply as anonymous market material.

Our approach is to document what can genuinely be observed: weight, color, treatment status, natural structure, source information, and realistic cutting possibilities.

For professional buyers, cutters, jewelers, collectors, and gemstone dealers, this allows each rough stone to be evaluated according to its actual characteristics rather than exaggerated expectations.
