What grade does Adil diamond ring belong to?

Pastoral diamond ring should belong to low-end products, right? Alas, I have never heard of the brand of this diamond ring, nor have I seen many bands. It's the first time I heard that this name should belong to a low-end brand, but since I dare to create my own brand, I'm sure the quality is fine, otherwise I won't come up with a brand. Don't worry. As long as the quality is good, the quality is reliable and the price is reasonable, there will definitely be fans, especially those civilians, especially those who are not very good.
