Vintage 10K IK Peridot & Diamond Gemstone Ring

Approximately a size 6. Has surface scratches, as shown in photos. 10K engraved underneath the setting, as shown. This ring is authentic gold. The green central gemstone is peridot, with smaller diamonds surrounding. Makers mark "IK©" inside the band. I wasn't able to find what the IK stands for, nor who makes it. But I did find some other comparable rings listed online with similar markings. My shipments are video recorded AND photographed, with distinguishing features noted and/or added to the object to ensure no scammers are successful. Unfortunately I've seen it all, and am 100% prepared to sell without anyone stealing from me. Thank you for your understanding.
