Brand new, unused. I tried it on my neck once. It's in new condition, but please understand that there may be minor scratches due to storage. Measured with a household scale, so there may be slight errors. Approximately 1-2g to prevent any issues. Sympathy of Soul 18k hallmark present. Although measured by an amateur, the thickness that can be passed through is about 3mm to 4mm. A 3mm chain could be passed through. The chain is for illustration purposes only and is not included. The warranty will be given to the buyer.
