34.50 ct Ceylon Blue Sapphire Rough from Elahera, Sri Lanka – Facet Grade Heated Rough with Large Cutting Potential

Stone Identity & Quality

This natural Ceylon blue sapphire rough weighs 34.50 carats and measures 25 × 16.5 × 9 mm. It was sourced from Elahera village around mining in Sri Lanka, one of the country’s recognized gem-producing areas. The stone is offered as facet-grade rough and is described as standard heated in rough form. Its clarity is included, which means internal features must be considered carefully during planning, but the overall size and body color still make it relevant for serious cutting evaluation.

The stone belongs to the category of larger rough sapphires where cutting decisions become especially important. In material of this scale, the final quality is influenced not only by color, but also by internal placement, structural stability, and the discipline of the cutting plan.

Color & Visual Characteristics

The rough shows a strong blue body color with a visibly rich internal tone when light passes through suitable areas. In rough form, sapphire color can appear uneven depending on thickness, surface texture, and the direction from which the stone is viewed. This piece shows a substantial blue presence that gives it visual weight and makes it attractive as a large rough specimen for transformation.

Its elongated rough outline and broad face also make it easier to study how the color may behave in different cutting directions. This is important, because in larger sapphire rough the final face-up appearance depends heavily on how the original body color is positioned and preserved.

Internal & External Features

Externally, the stone shows the natural surface features expected in sapphire rough, including uneven skin, natural breaks, and worn or partially worked surfaces. These are normal for gem rough and form part of the evaluation process.

Internally, the stone is included, and those inclusions are an important part of the cutting conversation. They do not automatically remove cutting potential, but they do require practical planning. In a stone of this size, internal features, zoning, and structural interruptions must be read carefully so that the best direction can be chosen. The value of the rough lies not in assuming perfection, but in understanding how much of the best material can be preserved.

Cutting & Treatment Potential

This sapphire is offered as standard heated in rough form, and any further cutting decision should be made with full awareness of its present treatment status and internal condition. Based on current size and shape, the material appears capable of supporting a substantial finished gemstone, and planning may suggest a result above 15 carats, depending on how the cutter manages orientation, inclusions, and final proportions.

That said, no exact recovery should be guaranteed from rough alone. Large sapphires often involve a balance between weight retention, clarity management, color placement, and final symmetry. This stone is suitable for experienced cutters or buyers who understand that the best finished result comes from reading the structure honestly rather than forcing maximum weight.

Source & Ethical Position

This sapphire was sourced from Elahera village around mining in Sri Lanka, through direct gem-area connections as geuda and we sent for standard heat treatment. At Danushka Gems & Minings, our approach is to present rough stones with clear origin information and practical gemological language, so the buyer can understand the material before transformation.

Source transparency matters, especially in rough gemstones where the journey from mining area to finished gem is a major part of the value. By working close to the source, we are able to offer stones with a more direct connection to Sri Lanka’s gem-producing regions and a more realistic understanding of their natural potential.
