38.67 ct Ceylon Mixed Facet Grade Rough Parcel – Dravite Tourmaline, Kornerupine, Chrysoberyl and Zircon from Rakwana and Kolonna, Sri Lanka

Stone Identity & Quality

This mixed rough parcel has a total weight of 38.67 carats and contains 8 natural unheated stones sourced from Rakwana and Kolonna villages around mining in Sri Lanka. Individual stone sizes range from 9.64 ct to 2.85 ct. The parcel includes a 4.40 ct dravite tourmaline, a 5.35 ct kornerupine, a 3.64 ct chrysoberyl, and the remaining stones are natural zircon. All pieces are offered as facet grade rough in natural condition.

This is a parcel intended for rough buyers, gem cutters, and collectors who appreciate the variety found in source-connected Sri Lankan gem material. Because the parcel includes multiple species, each stone should be evaluated independently for its own structure, transparency, color behavior, and cutting potential.

Color & Visual Characteristics

The parcel shows a natural range of colors from olive green and smoky green to golden yellow, honey, and soft brownish-champagne tones. This visual diversity is one of the main appeals of a mixed parcel, especially when it includes gem species with different refractive character and natural body color.

In rough form, these stones show their color in a more honest and geological way than finished gems. Some pieces appear more open under light, while others show stronger concentration depending on thickness, internal condition, and surface texture.

Internal & External Features

Externally, the stones show a combination of alluvial wear and natural rough surfaces. Some pieces retain rounded, frosted skins typical of river-transported gem material, while others show more angular breaks or exposed internal windows. These are normal and expected features in untreated rough.

Internally, each species in the parcel behaves differently. Zircon may show attractive transparency and warm internal glow, chrysoberyl may carry a more compact and structured look, kornerupine often presents a distinctive body character, and dravite tourmaline can show earthy color and directional interest. Because of these differences, the parcel should be approached as a group of individual cutting studies rather than one uniform lot.

Cutting & Treatment Potential

This parcel is offered in natural unheated condition, allowing the buyer to evaluate each stone in its original state. Cutting potential will vary from stone to stone depending on internal openness, shape, color placement, and how each species responds to orientation.

In a parcel like this, some pieces may be suitable for calibrated or custom faceted gems, while others may be more attractive for their species value and geological character. No fixed yield should be assumed in advance. The practical value of the parcel lies in the range of species and the ability to select different cutting directions based on each stone’s own structural strengths.

Source & Ethical Position

These stones were sourced from Rakwana and Kolonna villages around mining in Sri Lanka, through direct gem-area connections. At Danushka Gems & Minings, we work closely with source-region material and present it with clear origin information and realistic evaluation. Our focus is on natural gemstone rough, transparent sourcing, and practical understanding of the material before it enters the cutting stage.

A mixed parcel like this reflects the diversity of Sri Lanka’s gem-bearing areas, where more than one species can emerge from connected source environments and traditional mining networks.
