5.00 ct Ceylon Natural Unheated Lavender Blue Spinel Rough from Embilipitiya, Sri Lanka – Facet Grade

Stone Identity & Quality

This is a 5.00 ct Ceylon Natural Unheated Lavender Blue Spinel rough measuring 10.1 × 9.2 × 6.4 mm. The stone is sourced from Embilipitiya village around mining in Sri Lanka and is presented as facet-grade natural spinel rough.

The material has an attractive combination of color, depth, and strong vitreous luster. Its natural rough form remains visible, allowing cutters and professional gemstone buyers to study the stone before deciding on orientation, preforming, and final design.

No treatment and the stone is presented as natural and unheated.

Color & Visual Characteristics

The principal color is best described as lavender blue, with a noticeable violet influence depending on lighting, viewing angle, and the thickness of the rough.

Under stronger transmitted or direct light, some areas can appear lighter and more distinctly blue-lavender, while thicker portions can show deeper bluish-violet concentration.

The material also displays excellent vitreous luster, which is particularly noticeable across exposed natural surfaces. This strong surface reflection gives the rough a lively visual character even before polishing.

Internal & External Features

The rough retains natural external surfaces, irregular broken areas, and localized fracture-related features that are visible in the photographs.

These natural characteristics are important during cutting evaluation because some material may need to be removed during preforming before the final outline can be established.

The central usable body should therefore be inspected from several directions rather than judging the stone from only one face. For facet-grade rough, the objective is to identify the strongest combination of usable depth, color orientation, internal condition, and final face-up spread.

Cutting Potential

The stone has practical potential for custom faceting, but the final design should only be selected after close examination of the rough.

At 10.1 × 9.2 × 6.4 mm, the material has useful depth relative to its face dimensions. However, the natural exterior and localized fracture areas should be considered when estimating realistic recovery.

A cutter may evaluate several possible orientations before deciding whether an oval, cushion, modified cushion, freeform, or another custom design makes the best use of the material.

The objective should not simply be maximum carat retention. A successful result should balance:

lavender-blue color presentation,

removal or positioning of undesirable surface areas,

suitable pavilion depth,

symmetry,

light return,

and practical finished weight.

No particular final weight, clarity, or cutting result should be guaranteed before preforming.

Source & Ethical Position

This spinel comes from Embilipitiya village around mining in Sri Lanka, an area connected with Sri Lanka’s long-established alluvial gemstone environment.

At Danushka Gems & Minings, our approach is to present rough gemstones with practical information rather than promising results that cannot be known before cutting. We document origin, treatment information, visible natural characteristics, color, dimensions, and cutting considerations so cutters, dealers, jewelers, collectors, and international buyers can evaluate each stone realistically.

For suitable material, custom cutting and certification options can also be discussed.
