EXCLUSIVESean Kingston is being sued by a NYC jeweler for not paying for several pieces of really, really nice jewelry -- and two pieces of cubic zirconia ... TMZ has learned.
According to the lawsuit, filed in New York, Kingston got more than $200,000 worth of ice from Avi Da Jeweler from 2008-2013 ... but never paid for any of it. In the suit, Avi says Kingston wrote checks seven different times over the years, and they all bounced.
Avi claims the orders throughout the years included watches and chains (two featuring Kingston's initials), a diamond "Jesus piece," a belly button chain (we're guessing not for him) ... and a cubic zirconia necklace and bracelet.
The jeweler also claims Kingston never returned a $12,000 ring he loaned him for a "106 & Park" appearance.
In all, Avi claims he's owed $226,200 and he wants an additional million bucks in punitive damages.
A rep for Kingston tells TMZ, "Mr. Kingston has paid Avi Da Jeweler well over $300,000 for jewelry that was appraised at far less than that and has the cashed checks to prove it. Additionally, no one would continue to supply jewelry to another individual for 5 years without ever receiving payment. Mr. Kingston fully intends to fight this lawsuit in a court of law."
