Diamond is a solid form of carbon with a diamond cubic crystal structure. At room temperature and pressure it is metastable and graphite is the stable
form, but diamond almost never converts to graphite. Diamond is
renowned for its superlative physical qualities, most of which originate
from the strong covalent bonding between its atoms. In particular, it has the highest hardness and thermal conductivity
of any bulk material. Those properties determine the major industrial
applications of diamond in cutting and polishing tools and the
scientific applications in diamond knives and diamond anvil cells.
There weight is 30 / 30 cents

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.
When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.
