I can't directly evaluate the credibility of Sunrise jewelry and gold. However, the standard of gold purity exists objectively, and whether the gold of Sunrise Jewelry meets the purity standard can be determined by inspection. If the gold is marked with thousands of pure gold, it means that its purity is above 99.9% and it is qualified. If you are in doubt about the gold of Sunrise jewelry, you can take it to a special quality inspection center for inspection.
