Opal rough from Welo, Ethiopia, 73.67 carats, with a large gem area and deep colour play dominated by intense orange, yellow and red hues.
Description from the seller
Rough opal of very large size, offering a broad and deep gemstone zone. The dominant hues are an intense orange, mixed with bright yellow and internal reds visible from certain angles. The play of colors manifests on the surface as well as in depth, with a dense material and beautiful transparency in the heart of the stone.
Technical specifications
Weight: 73.67 carats
Dimensions: 36 × 24.6 × 20.7 mm
Origin: Welo, Ethiopia
Raw hydrophane opal in matrix.
Color scheme: Very intense, dominated by warm tones.
Visible colors: orange, yellow, red, touches of green.
Structure: significant gemstone volume, smooth and clean internal walls.
Particularities / Remarkable points
One of the largest pieces among Welo rough opals, rare in this category.
Exceptional colored zone in its depth and uniformity.
Very beautiful contrast between the matrix and the gemstone material well displayed.
Piece suitable for the collection, for lapidary work, or for highlighting as it is.
Geological context
From the volcanic deposits of Welo, this opal illustrates the strong luminosity and warm tones characteristic of hydrophane opals from the region.
Conclusion
Superb 73-carat rough opal, impressive due to its size, the depth of its gemstone zone, and its dense, warm play of colors.
Attention
95% of Ethiopian opals are naturally hydrophilic: they love water and can absorb a small amount of it.
That is why it is better to keep them in a small container of water when you are not handling them.
This helps preserve their stability, prevent micro-variations in color caused by drying, and maintain a beautiful, constant play of light.
