the drain has a U-shape trap...so when it's completely dry you can try to use a piece of gum at the end of a wire (clothes hanger?) and try to pick up the diamond from the trap but better be careful when doing this cuz if it drops throught the trap it's game over.

here's a better illustration...

you might want to access from the overflow opening...depends on your design...you might even need to rip the drywalls out from the other side to see the pipes...

but for a diamond I'll do anything!

since it's a fairly straight pipe (from overflow), it might not be that hard, give it some time and a big big piece of gum!

Arra..  the u-tube wasn't there to trap items, but designed to trap small amount of water bor.  Remember what happened in ToDai during SARS day?

you're correct, that's another use of that U trap...is to keep mice (yes mice or insects!) and fumes from flowing back
