AI-assisted summary
Description from the seller
From the collection of rare and important minerals: a large, transparent mammillated opal from Sardinia (Italy)! These opals, which are not at all common on the market, display numerous colorful reflections that make them particularly aesthetic. However, the most important characteristic is their sensitivity to ultraviolet light. In fact, they are fluorescent and tend to turn a deep green! (UV light 365 nm, 15 W).
A unique natural specimen, ideal for enriching high-level mineral collections and perfect for decorating exclusive environments thanks to its high aesthetic value.
Photos are taken in a dedicated set with intense lights to avoid altering the colors, but it is recommended to display the minerals in well-lit environments to fully appreciate their tones.
The shipment usually occurs the next day, with tracking and careful packaging. Multiple orders from the same customer will be grouped, and any excess shipping costs will be refunded.
