24.99 ct Natural Unheated Ceylon Multi-Color Sapphire Rough Parcel – 30 Pieces, Sri Lanka

 Stone Identity & Quality

This 24.99 ct natural unheated Ceylon multi-color sapphire rough parcel consists of 30 individual pieces of corundum rough sourced from several established gemstone-producing areas of Sri Lanka.

The collection contains 9 blue sapphires, together with pink, purple, white, peach, violet, and bi-color sapphire material. It also includes one Sri Lankan ruby weighing 1.28 ct.

The individual stones range from 0.40 ct to 1.28 ct, making this a mixed-size parcel of relatively small rough stones intended for individual professional cutting evaluation.

Sapphire and ruby both belong to the mineral species corundum, with the chemical composition Al₂O₃. Their different color varieties are associated with trace elements and color-causing mechanisms within the mineral structure. This is general gemological information, not a laboratory analysis of the individual stones in this parcel.

The collection is described as facet grade, with natural unheated treatment disclosure.

 Color & Visual Characteristics

The most interesting characteristic of this collection is its range of natural corundum colors.

The parcel includes blue, pink, purple, violet, peach, white, and bi-color sapphire rough, with a ruby adding another red-family corundum variety.

Nine pieces are identified as blue sapphires, providing a distinct blue group within the parcel. The remaining material displays different colors and tones, allowing cutters to evaluate the stones individually rather than treating the collection as a uniform batch.

The supplied photographs show a combination of saturated and lighter-colored rough stones. Some pieces appear more translucent, while others show areas of greater light transmission. Natural variations in color distribution and surface texture are visible.

For professional cutting, the direction of light transmission, body color, and any color concentration should be considered before selecting a cutting orientation.

 Internal & External Features

The photographs show irregular, naturally worn rough forms consistent with the parcel’s alluvial presentation. Several stones display rounded edges, uneven surfaces, and natural surface markings.

The degree of transparency varies between individual pieces. Some show visible internal features or less transparent areas, while others appear to transmit light more readily.

These characteristics are important during rough evaluation because an apparently attractive surface color does not automatically indicate the same color or clarity throughout the stone.

Professional examination under suitable lighting and magnification can help identify internal features, fractures, color zoning, and potentially useful cutting areas.

The photographs alone do not establish formal clarity grades, the exact nature of every inclusion, or the finished appearance after cutting.

Cutting / Specimen / Finished Gemstone Potential

This is a facet-grade rough parcel intended for professional lapidary assessment.

Because the stones range from 0.40 ct to 1.28 ct, cutting decisions should consider the limited size of each piece. Preserving useful body weight while achieving suitable color presentation and removing undesirable surface or internal features may require different approaches for different stones.

A cutter may examine the parcel according to color, transparency, available depth, shape, and internal structure.

The blue sapphires can be evaluated separately from the pink, violet, peach, white, and bi-color pieces. The 1.28 ct ruby should also be assessed individually, with attention to its natural shape and internal characteristics.

No finished shapes, cutting recovery percentages, or final clarity grades are guaranteed. The appropriate cutting plan depends on direct examination of each stone.

Custom cutting or further evaluation can be discussed where suitable.

 Origin & Source Story

This collection comes from four Sri Lankan gemstone-producing locations:

Ratnapura village around mining in Sri Lanka.

Nivithigala village around mining in Sri Lanka.

Pelmadulla village around mining in Sri Lanka.

Embilipitiya village around mining in Sri Lanka.

These areas form part of Sri Lanka’s long-established gemstone trade, where alluvial gemstone material is recovered, selected, evaluated, and supplied through local sourcing networks.

At Danushka Gems & Minings, our work involves visiting Sri Lankan gemstone-producing villages and maintaining relationships with miners, mine owners, local buyers, and source dealers.

Working close to these areas allows us to encounter a broad range of natural corundum material, from individual stones to mixed-color rough collections.

This parcel reflects that source-area diversity, bringing together material from several locations in one collection.

 Treatment / Cutting / Certification Notes

The supplied treatment disclosure for this parcel is Natural Unheated.

No gemstone laboratory certificate has been provided in the product details. The unheated description therefore represents the source treatment information and should not be presented as an independent laboratory conclusion.

Professional cutting evaluation can be arranged where suitable, and certification requirements may be discussed before or after cutting.

The parcel is offered as natural rough, and no heating outcome, finished appearance, cutting recovery, or laboratory grading result is guaranteed.

 Why This Stone Is Interesting

The practical appeal of this parcel is its combination of colors, individual sizes, and source locations.

For gemstone cutters, it provides multiple pieces of corundum rough for separate cutting decisions. For dealers and collectors, the range of natural sapphire colors offers an opportunity to compare different appearances within the same mineral species.

Jewelry designers may also find the color selection useful when planning small colored-gemstone projects, subject to the results of professional cutting.

The included ruby adds another corundum variety to the collection.

Source & Ethical Position

Danushka Gems & Minings focuses on maintaining close relationships with Sri Lankan gemstone source areas and presenting natural gemstones with practical, transparent information.

Our approach includes regular travel through mining communities, careful selection of individual rough stones, clear disclosure of known treatments, and attention to the possibilities and limitations of cutting.

We believe a gemstone should be represented according to what is actually known about it, rather than through unsupported claims about rarity, clarity, recovery, or finished value.

Our source-connected work also supports ongoing commercial relationships with participants in Sri Lanka’s gemstone-producing communities. It does not, by itself, establish independent ethical certification or traceability to a particular mine.
