Stone Identity & Quality
This is a 19.35 ct natural Ceylon violetish blue sapphire rough measuring 18.5 × 13.1 × 8.8 mm. The stone was sourced from Ratnapura village around mining in Sri Lanka.
It is natural and unheated, slightly included, and classified as facet-grade rough. The stone retains a substantial body and depth suitable for professional cutting evaluation.
Its larger rough size provides several possible orientation considerations, although the final cut and recovery should only be determined after detailed examination and pre-forming.
Color & Visual Characteristics
The sapphire displays a violetish blue body color with a subtle shift toward pinkish purple depending on lighting conditions and viewing direction.
Under cooler light, the stone appears predominantly violetish blue, while under warmer or differently balanced light, the pinkish-purple component becomes more visible.
This is best described as a subtle color shift rather than a dramatic color-change phenomenon.
The stone also displays a soft internal silkiness in certain areas, contributing to its natural visual character.
Internal & External Features
The rough is slightly included and contains small silky internal features.
Natural internal inclusions and structural features are visible through the body, particularly under transmitted or concentrated light.
The rough surface also retains natural marks and irregularities associated with its original form.
These internal and external characteristics need to be considered during orientation because inclusions, silk, color distribution, and depth can influence the final cutting plan.
Cutting, Specimen, or Treatment Potential
This is primarily a facet-grade cutting rough rather than a specimen stone.
Because of its 18.5 × 13.1 × 8.8 mm proportions, the rough provides useful depth and body for a substantial finished gemstone. However, the final shape should not be predetermined only from the outside appearance.
A professional cutter should first evaluate:
* The strongest and most attractive color direction
* Distribution of the violetish blue color
* Position of silky areas
* Internal inclusions
* Cleanest cutting zones
* Available depth
* Potential symmetry
* Weight retention
Depending on internal orientation, the final design could prioritize weight, clarity, color concentration, or a balance of all three.
No final finished weight or exact cutting result should be guaranteed before pre-forming.
Source & Ethical Position
Danushka Gems & Minings works directly with gemstone-producing areas throughout Sri Lanka, sourcing natural rough stones through miners, mine owners, local buyers, and source dealers.
Our approach is based on practical gemstone evaluation, honest disclosure, and clear presentation of each stone’s natural characteristics.
Rather than overpromising cutting results, treatment outcomes, or value, we present the rough as accurately as possible so buyers, cutters, collectors, and jewelers can evaluate the material based on its real characteristics.
