More reliable. It was customized by others. Instead of asking customers to pay all the money at once, they ask customers to pay half of the deposit first and then pay the rest when they come to pick up the diamond ring. The diamond ring is ready, and the customer is satisfied with it, and then pay the balance. Moreover, there is a diamond ring certificate. A diamond ring with a score of more than 30 points is a double certificate, the most authoritative GIA bare diamond certificate in the world, and a national finished diamond ring certificate. A diamond ring is safer. Ensure that every piece of jewelry sold supports national repeated testing. Moreover, we only sell a new diamond with one hand, change the ring number for free for life, clean and care, including some customers who don't like the current style in the later period, and can also change the style and only charge the labor fee, because this is also a service.
