That’s a weird stone
Our furniture is seldom made out of stone, but some are still used in different ways and industries, primarily appreciated in jewelry making. Big and wealthy companies and mines exploit the Earth in search of unique rocks, which are very high priced.
Nevertheless, rocks don’t need to be high-priced to be beautiful. The romantics or children would pick something like this up and let nature amaze them with different patterns, colors, sizes, and shapes. Of course, as long as they are not trypophobic.
