This is a ring that has a story. My sister bought this on Jewelry TV for black diamonds. But we don't know if they are diamonds or marcasite ...because I ran it thru the rock finder and it would go back and forth fron marcasite to diamonds. So I am selling it as marcasite ..so I don't mess up . She paid 300 about 20 years ago...gave it to me and I never wear it ...so I am going to say it's in good condition my sister wore...it is still pretty and has sparkle. Thank you forblooking .
