Why are diamonds usually depicted orientated like in OP's pic? Wouldn't that be upside down, as they cannot balance themselves on a single point like that, and when you flip it over to its proper orientation it is very similar to a pyramid.

If they pictured it the other way, maybe it reminds people they won't even be able to see the pointy part once it's set in the ring. At this point, that shape is now the symbol of the diamond anyway. Superman, any advertising logo that uses a diamond, etc. If it was turned upside down it would lose its power to influence.
