We've just finished new batches of our antimony and zirconium ingots. We know we are out of our very popular ruthenium and iridium ingots. We are considering releasing Ru in one troy ounce powder (aka sponge) form while we work on a more cost effective manufacturing solution for these ingots. We've got the same issue with iridium which is also very expensive to manufacture. We hope to get this resolved in 2019. Own what's rare!
