"Glee" star Jenna Ushkowitz hit up the GLAAD Media Awards last weekend in L.A. -- and she was gleaming in over $118,000 worth of diamonds.

We're told Jenna was adorned head to fingertip in Tacori -- wearing the line's $30,000 hexagonally linked earrings, an $88,000 bracelet and a ring which retails for $8,190.
Looking that sparkly really adds up!
