Natural Spinel Rough · 8.515 ct · For Faceting · Unheated · Brownish Orangey Yellow

This natural Spinel rough weighs 8.515 ct and is offered specifically as rough material for faceting. The specimen displays a warm brownish orangey-yellow colour range, with lighter amber-toned areas alternating with deeper brown zones across the rough crystal.

The surface retains a strongly natural, irregular morphology with rounded growth areas, shallow cavities, uneven crystal contours and locally textured surfaces. These features give the specimen a distinctly unworked appearance and provide useful visual information for a cutter when assessing orientation and usable material.

The Rough Spinel is translucent rather than fully transparent. Light penetrates portions of the rough, particularly through the lighter orangey-yellow and amber-brown areas, while denser brown zones appear more subdued. This variation in translucency and colour concentration creates a naturally heterogeneous appearance that should be taken into account during cutting.

Several areas show stronger brown saturation, while other sections reveal warmer orangey-yellow tones under direct light. Careful orientation may allow the cutter to favour the lighter and more attractive colour zones while working around darker concentrations and natural surface irregularities.

The substantial 8.515 ct starting weight provides useful material for evaluation, although the final faceted yield will depend strongly on the internal structure, orientation, removal of surface irregularities and the cutter’s chosen design. The rough shape does not suggest a predetermined final cut, leaving flexibility for individual planning.

Natural Spinel is a magnesium aluminium oxide, MgAl₂O₄, with a hardness of 8 on the Mohs scale and no cleavage, making successfully cut material suitable for durable jewellery use. This specimen is unheated and untreated, preserving its natural brownish orangey-yellow colour, translucency and original rough crystal character.

With its substantial starting weight, warm natural colour range and strongly individual rough morphology, this Spinel is best suited to an experienced cutter looking for distinctive faceting material rather than uniform commercial rough.
