Please review the profile. These are high-quality ornamental stones collected by my grandfather. The "Red Stone," imbued with the protective power of vermilion (red). Red Stone is a stone formed when quartz contains a large amount of iron oxide, bound together by high heat and pressure. It is extremely hard and develops a transparent luster when polished. The beauty of the Red Stone's color is magnificent. Since ancient times, vermilion (red) has been said to ward off evil, Red Stone is considered an auspicious stone, and has been displayed as a guardian stone in the entranceways and alcoves of homes. In foreign countries, it was revered as a "sacred stone," and it was believed that wearing it would provide energy from the sun, making it highly valued. However, in recent years, the amount produced has almost disappeared, making it a very valuable stone as a garden stone, ornamental stone, and precious stone.
