・No accessories included. ・I apologize, I don't know the product name. ・There is no material marking plate inside the ring, so I think it's black synthetic corundum, but I don't know the details... I bought it new about 12 years ago when I was a student, so I think it was a rank of about 30,000 to 40,000 yen when it was new. ※Purchased from HAPPINESS I don't suit it, so I've only used it once or twice. I can't tell with the naked eye, but because I stored it in the same box as other accessories, there are some scratches and dirt. ・Please consider and purchase it, understanding that it is a used item. ・Even if negotiations are in progress, we will give priority to the person who purchases it first. Thank you. ・I don't smoke, and I don't have any pets. ・I will arrange for delivery via Takkyubin Compact. ・To prevent replacement, we do not accept returns, so please purchase after you are satisfied.
