We just received back the first ingot from our recently kicked-off iridium and ruthenium buy-back program. It is now listed for sale. It is a nicely polished ruthenium ingot with serial number 0338 in great condition. We will release ingots from this buy-back program for re-sale on our site as an option on the drop-down menu just below the page header of the original product page. Own what's rare!
