Gisele sparkles (and the ring's not too shabby either!) Photo by Getty Images

Tom Brady may have outdone himself, literally. The cute quarterback has clearly been supermodel Gisele's accessory of choice, but from the looks of it, things may have changed.

After major buzz about a ringless Gisele (since the couple's secret wedding on February 26th in Santa Monica, Calif.), the Brazilian beauty showed up at last night's Rainforest Alliance gala in New York City sporting some serious bling -- her wedding ring and band. They are blinding and Tom was nowhere in sight!

According to the Diamond Information Center, the rock appears to be a 4 carat round, brilliant diamond on a 4-prong setting set in platinum; estimated value is $100,000. What better to go with her pavé diamond wedding band?

We'd pay to see Gisele's touchdown dance.
