This is a 1.36 gram sample of a complex precious metal alloy. It's notable for its 46.371% total precious metal content. The alloy's composition includes:

• Ruthenium (Ru): The most abundant element at 22.16%, ruthenium is a hard transition metal often used in electrical contacts and as a hardening agent.

• Osmium (Os): Present at 12.15%, osmium is a very dense transition metal used in alloys needing extreme hardness.

• Iridium (Ir): At 6.06%, iridium is a corrosion-resistant, dense precious metal used in various applications.

• Platinum (Pt): At 4.66%, platinum is a well-known precious metal valued for its catalytic properties and corrosion resistance.

• Gold (Au): The presence of 1.341% gold adds to the alloy's value.

This alloy's blend of platinum group metals and gold likely gives it unique properties tailored for specific applications requiring high temperature resistance, corrosion resistance, and/or catalytic activity.
