Just days after details of her stunning 4-carat engagement ring were revealed, Reese Witherspoon is finally showing off her new sparkler in public. The actress flashed her impressive ring in L.A. on Tuesday, while sitting courtside at a Lakers game with fiancé Jim Toth by her side. Reese was all smiles as she took in the match-up against the Detroit Pistons, no doubt in part due to the gorgeous new sparkler on her left hand. The rare Ashoka diamond stunner, set on a pave diamond-and-platinum band, was custom-designed by the William Goldberg Diamond Corporation. The center stone features 62 displayed facets and rounded corners to create a dazzling sparkle–fitting for the happy couple.
