AI-assisted summary
Description from the seller
Large transparent opal rough – honey yellow to orange-red – striking natural inclusions
Exceptionally expressive unpolished rough stone with high light transmittance, intense color effect, and numerous clearly visible inclusions and internal structures.
The piece is particularly characterized by the interplay of transparent to translucent areas, strong color zoning, and dark inclusions. In sunlight its appearance changes considerably: while in normal illumination it appears partly very light and transparent to champagne-, honey-yellow, and gold-colored, in backlighting it develops intense golden-yellow, cognac-colored, orange, and deep orange-red tones.
Color and transparency
The stone is not uniformly colored. It shows pronounced naturally appearing color zoning with transitions between:
* nearly colorless to very light transparent areas
* champagne and honey yellow
* golden yellow
* cognac and amber-orange
* vivid orange
* reddish-orange to deep reddish-brown areas
Especially striking is the considerable light transmittance. Even through relatively thick areas of the rough piece, strong sunlight penetrates. In backlighting this creates an intense, sometimes glowing orange-red color effect.
Inclusions and internal structures
A key characteristic of this piece is the numerous visible inclusions.
Inside there are differently pronounced dark to nearly black inclusions, sometimes dot-like or rounded, sometimes elongated, branched, or irregular. Some appear almost freely enclosed in the transparent material when viewed in transmitted light.
In addition, there are fine needle-like or linear structures, dark veins, and other smaller inclusions visible. Due to the high transparency, these structures can be traced deep into the interior of the stone.
Particularly noticeable are several larger dark inclusions, which in sunlight against light create a strong contrast with the gold-orange illuminated material. On various photographs these can be viewed from different angles.
The inclusions are therefore not merely a surrounding feature for this piece, but one of its essential visual characteristics.
