History:
However, we can guess. The names uncommonness suggests it might have started in one small area, maybe as a nickname or a job title related to gold (since "karat" is linked to gold weight). People with this surname probably moved to new places looking for better jobs or a better life, slowly spreading the name. While forced movements like wars might have played a small part, its unlikely to be the main reason for the surnames spread. Without more information, figuring out exactly how this surname spread remains a challenge.
