AI-assisted summary
Description from the seller
This lot consists of 30 rough Welo opals from Ethiopia, partially cabbed or rough-cut, with a declared total weight of 11 grams (about 55 carats). (The scale reads 12 g including the bag)
Description and Characteristics
Opals from the Welo region are renowned for their hydrophane nature (the ability to absorb water, temporarily changing transparency) and for the vividness of their flashes.
* Play of Color: The specimens exhibit good iridescence, with electric color flashes ranging from neon green to fire orange/red, and touches of yellow and blue. Some pieces show a very lively “flash” pattern.
* Body Tone: Varies from a primarily white/creamy base to semi-transparent (crystal opal) and slightly amber.
* Form and Condition: They are not finished gemstones for classic jewelry. They are “nuggets” or small nodules that have undergone only a initial cabbing or rough shaping. They retain freeform shapes and, in some pieces (as seen in the last macro photo), small portions of the dark siliceous host rock or natural surface inclusions are still present.
1. Cutting yield: Being free-form and irregular, if a cutter wanted to produce perfectly symmetrical cabochons for rings, the material would suffer a weight loss of about 40–50%.
2. Matrix presence: The rock still attached to some pieces slightly reduces the gem’s purity but confirms authenticity.
3. Excellent for artisanal use: They retain the maximum value when used as-is for handmade jewelry in a raw/boho style (e.g., wire-wrapped settings) or for collecting.
*Note: I am not an expert in the field; I leave it to a professional to evaluate whether the lot is natural mineral or synthetic*
