Stone Identity & Quality
This is a 2.31 ct Facet Grade Ceylon Natural Blue Sapphire Rough, measuring 5.8 × 5.6 × 5.5 mm. The stone is a natural unheated alluvial sapphire rough from Ceylon, Sri Lanka, with clean internal structure and medium blue color. Its compact body and useful depth make it suitable for buyers looking for natural sapphire rough with custom cutting potential.
Color & Visual Characteristics
The stone displays a medium blue sapphire body color with good visual presence for its size. Under light, the blue color appears through the rough body, allowing the cutter to study orientation and possible final appearance before cutting. The color is described in its current rough condition, and the final result after cutting or treatment will depend on planning, polish, and the stone’s natural structure.
Internal & External Features
This sapphire rough has a rounded alluvial form, shaped naturally through Sri Lanka’s gem-bearing environment. The stone is described as clean internally, giving it better potential for careful cutting compared with heavily included rough material. Some natural surface features are visible, which is normal for uncut alluvial sapphire and should be considered during cutting preparation.
Cutting & Treatment Potential
As facet grade rough, this sapphire can be studied for a custom faceted gemstone. Its 5.5 mm depth gives the cutter room to consider several cutting directions, but the final shape should be selected only after physical inspection, orientation study, and yield planning. The stone is currently unheated and may be considered for professional heat treatment to try to strengthen the blue color, but treatment results should not be guaranteed because every sapphire reacts differently.

This blue sapphire rough is from Ceylon, Sri Lanka, a country respected worldwide for natural sapphires and long gemstone traditions.
