AI-assisted summary
Description from the seller
The Amethyst is a variety of violet quartz (SiO2) whose color results from ferric ions (Fe3+) exposed to natural irradiations. Brazilian geodes from Rio Grande do Sul form in basaltic cavities—empty spaces left by gas bubbles in cooled volcanic rock. The filling occurs over millions of years by hydrothermal precipitation. The heart shape is the result of specialized Brazilian craftsmanship: manual cutting in a natural geode, a very precise and laborious technique that represents a significant added value. Visual analysis shows a color from deep to very intense purple (Premium evaluation). The crystal size is 4-8 cm, well-formed, making this stone a reference piece. Marked metallic flashes and bright faces (flashes and luster evaluation rated Excellent). The heart shape is well proportioned, the cut is clean (the evaluation is said very successful). The piece is mounted on a handmade metal base and by a supporting arm valued at about €300. The back is dense across the entire surface; the evaluation is rated excellent.
It is a monumental unique piece suited to a prestige collection, an exceptional space, or an artistic space.
