With many of my cabochons and especially my stone heart cabs I can drill a hole into the edge of the stone if it's thick enough, or in the cleft of a heart cab, and add a sterling silver screw eye bail to turn it into a pendant! Cabs can usually easily become pendants! It's best to check with me first. Just send me a message with the code number from the title of the cab you are interested in having drilled and I will verify that the cabochon is appropriate for drilling before buying this additional drilling service with the cab. If I agree then buy the cab and this service and I will drill the cab and glue in the bail for shipping. Please allow an extra 1 to 2 business days to the processing time for the order I have to drill and glue. I always let the glue cure before I ship!
