For example, Bao Hui Jewelry spends more than 500 million yuan every year to purchase from mines all over the world. The raw materials of gemstones are amethyst from Kariba, Zambia, turquoise from Sleeping Beauty, Arizona, and diamonds from Golconda, India. With superb product development capabilities and professional advantages of leading fashion, we have numerous private high-end customized products, many of which are invited by high-end cultural art galleries and exhibition halls around the world for exhibition, auction and collection. How can this be measured by price?
