IKc10KR Stamp on hold ring information needed

[86made]

I know what the numbers mean, as far as it goes carat wise on a ring, and I'm pretty sure the circle with the c means copyright, but does anyone know if that is an IK or a JK or an LK at the beginning and what that means, I think it's initials is what I kinda found online, but can't find any information about KR at the end.. anyone know what this stamp means?
