Lindsay Lohan is out in Greece showing off a new ring ... and it doesn't look a thing like the engagement rock she got from ex-fiance Egor Tarabasov.
Bikini-clad Lindsay was in Mykonos this week with a yellow gem on her left ring finger. She's reportedly been hanging in Greece with restaurant owner Dennis Papageorgiou ... fueling rumors she's moving on from Egor after their blowout fight.
Y'know what Egor's thinking -- where the hell's my emerald??!!
