6.56 ct Unheated Ceylon Padparadscha Sapphire Rough – Facet Grade Sapphire from Ratnapura, Sri Lanka
Stone Identity & Quality
This 6.56 carat natural Padparadscha Sapphire rough measures 10.5 × 9.5 × 5.7 mm and originates from Ratnapura village around mining in Sri Lanka, one of the world’s most respected sapphire sources.
The stone is presented in its natural unheated condition, preserving the geological characteristics formed within Sri Lanka’s metamorphic gemstone environment. Despite visible inclusions, the stone still falls within the category of facet-grade rough, meaning it can be evaluated by a professional cutter.
Color & Visual Characteristics
The sapphire displays a soft peach-to-pinkish orange tone, a color combination commonly associated with padparadscha sapphire. This delicate color balance results from trace elements present within the corundum crystal during formation.
In rough form, the color can appear subtle and may change visually depending on lighting and cutting orientation.
Internal & External Features
This rough sapphire contains natural internal inclusions, which are typical in padparadscha sapphire material. These features often guide cutters in planning how the stone should be oriented during the cutting process.
Externally, the stone shows typical alluvial surface wear, indicating that it was naturally transported through Sri Lanka’s gem-bearing river gravels before being discovered.
Cutting & Treatment Potential
Gem cutters typically evaluate sapphire rough based on:
Inclusion placement
Color distribution
Stone depth and geometry
Orientation for faceting
Although inclusions are present, the stone still offers cutting potential, depending on the lapidary’s approach. Orientation decisions may focus on preserving color balance while minimizing the visual impact of inclusions.
The sapphire is offered unheated, allowing the buyer to decide whether to preserve the natural state or consider future treatment options.
Source & Ethical Position
This sapphire originates from Ratnapura village around mining in Sri Lanka, part of the island’s historic gem belt known for producing many varieties of natural sapphire.
Sri Lankan sapphires are primarily found in secondary alluvial deposits, where crystals formed in metamorphic rocks before being transported into river gravels over geological time.
