Stone Identity & Quality
This is a 44-piece parcel of Ceylon Natural Standard Heated Blue Sapphire rough, with a combined weight of 23.30 ct. Individual pieces range approximately from 0.80 ct to 0.30 ct and were sourced from Pelmadulla village around mining in Sri Lanka.
The parcel is classified as facet-grade rough and consists of smaller sapphire pieces suitable for professional cutting evaluation, particularly where calibrated gemstone production is required.
An important part of the identity of this parcel is its treatment history. Prior to heating, the material consisted of young geuda, dun geuda, and silky geuda-type pale to white sapphire selected for its heating properties. Following standard heat treatment, the stones developed their present blue colors.
Color & Visual Characteristics
The parcel displays a natural range of medium-light through stronger blue colors rather than one completely uniform blue tone.
Individual pieces vary in saturation and transparency. Some show an open lighter blue appearance, while others display deeper or stronger blue concentration. This variation should be considered when matching stones for calibrated sets or planning individual finished gemstones.
Internal & External Features
As a parcel of natural sapphire rough, the pieces show variations in natural surface form, transparency, internal structure, and remaining silky characteristics.
Because the original material included young geuda, dun geuda, and silky geuda types, each stone should be examined individually before cutting. Even stones of similar rough weight can produce different finished results depending on depth, internal features, orientation, and usable clean area.
Cutting, Specimen, or Treatment Potential
This parcel is intended primarily as facet-grade cutting material.
With individual rough weights of approximately 0.80–0.30 ct, the parcel can be evaluated for approximately 6–2 mm calibrated designs. Possible finished sizes depend on the geometry and usable area of each individual rough.
For calibrated production, cutters should sort the parcel according to color, rough dimensions, depth, orientation, and expected yield before establishing the final cutting plan.
The stones have already undergone standard heat treatment. No particular finished weight, calibrated size, or cutting result is guaranteed before professional evaluation.
Source & Ethical Position
Danushka Gems & Minings works with source-connected gemstone material from Sri Lanka and focuses on providing practical information about each stone or parcel, including origin, treatment, rough characteristics, and intended use.
This parcel is connected to Pelmadulla village around mining in Sri Lanka. Its geuda origin and subsequent standard heating are openly stated so professional buyers understand the material they are evaluating.
Our objective is not to present treated material as something it is not, but to clearly explain its natural sapphire identity, treatment history, present appearance, and practical cutting possibilities.
