Where to get a replacement diploma?

Graduated a NYC high school in 2010, can't find my diploma anywhere. Where can I acquire a replacement one?

(Also would the HS transcript be enough to prove that I did graduate?)

your high school

Have you tried calling your school?

Yeah I guess the most obvious place is the one to start at. Thanks.

Not yet, I started searching 3 hours ago (10 PM).

Im in NYC also and i know high schools keep records their students even if they graduated. Also diplomats aren't made in a special place the school makes them its just a diploma print out where they put your name with the printer and add a stamped gold sticker Ive seen them make a diploma in front of me so I suppose they could make a new one for you. Also they give you transcripts in sealed envelopes that are taped on the edges and stamped with the schools logo or name that are to be open only by however you showing it to job interview, college etc. hope that helps

check with your HS, then your school district (which your HS might refer you to)
