50 ct Natural Unheated Alexandrite Rough Parcel – 60 Facet-Grade Pieces from Madagascar

Stone Identity & Quality

This parcel contains 60 pieces of natural unheated facet-grade alexandrite rough with a combined weight of 50 ct. Individual stones range from 1.50 ct to 0.35 ct, with an average weight of approximately 0.80 ct per piece.

The material was sourced through direct source connection from Madagascar. It is presented as a mixed cutting parcel for gem cutters, dealers, jewelers, collectors, and buyers interested in natural color-change chrysoberyl.

Each piece has its own shape, transparency, internal structure, color response, and possible cutting yield. Although the parcel is classified as facet grade, every stone should still be inspected individually before a final cutting decision is made.

Color & Visual Characteristics

Under cooler or neutral light, the rough shows green, yellow-green, gray-green, and olive-green appearances. Under warm or incandescent lighting, many pieces shift toward pinkish, purplish-pink, reddish, or warm rose tones.

The visible color change varies throughout the parcel. Some stones may show a stronger transition, while others may display a softer change or only partial color movement. This variation is normal in a mixed natural alexandrite rough collection.

The apparent color is also influenced by stone thickness, light source, transparency, surface texture, and cutting orientation. The final face-up color cannot be guaranteed before preforming and polishing.

Internal & External Features

The stones show natural rough surfaces, irregular alluvial or broken crystal forms, internal inclusions, fractures, veils, and areas of different transparency.

Some pieces appear relatively clean through selected directions, while others may require careful positioning to avoid surface-reaching features or heavily included areas. Natural zoning and uneven color concentration may also be present.

Directional lighting and magnification should be used to examine each stone before cutting. This allows the cutter to study the cleanest areas, strongest color direction, available depth, and safest possible shape.

Cutting, Specimen, or Treatment Potential

This is a facet-grade alexandrite rough parcel intended mainly for cutting evaluation and small finished gemstone production.

Possible finished designs may include oval, round, cushion, pear, marquise, freeform, or mixed cuts, depending on the natural outline and depth of each piece. Some stones may be suitable for calibrated sizes, while others may require custom designs to retain more weight or manage internal features.

The cutter should balance color-change performance, clarity, weight retention, durability, and light return. No exact finished weight, color-change strength, clarity grade, or final shape can be promised before cutting.

The parcel is presented as natural unheated alexandrite rough. Custom cutting and laboratory certification can be discussed where suitable.

Source & Ethical Position

This alexandrite rough was sourced through direct source connection from Madagascar.

Danushka Gems & Minings focuses on honest rough presentation, practical cutting guidance, transparent source information, and realistic descriptions. We do not guarantee final cutting results before examination, and we clearly distinguish visible potential from confirmed finished outcomes.

Our approach is designed for gem cutters, collectors, jewelers, dealers, and international buyers who value natural gemstone material, responsible communication, and careful mine-to-market presentation.
