This is an amazing custom designer ring. 1.51 ct GIA certified diamond placed in a 0.82ct Micheal M band. The band is high polished 18ct white gold. The GIA serial # is laser inscribed on the girdle of the diamond to prove it is the diamond in the report. It was just rhodium dipped, cleaned and prongs tightened. I have the receipt of the maintenance. I also have the appraisal and diamond report from GIA. You can also buy the matching Micheal M bands for this ring that fit perfectly and look amazing. You need to see this in person. Pics dont do it justice. I can tell you much more if interested
