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.

LeAnn Rimes isn’t the only A-lister making news today with a mega-watt engagement ring. Reese Witherspoon‘s sparkler has just been revealed as well. A rep for the Oscar-winning actress confirms that Reese’s fiancé, Jim Toth, 40, proposed with a 4-carat Ashoka diamond stunner set on a pave diamond-and-platinum band, similar to the one pictured above. So how did Toth land on the special sparkler? “In the past year, the retro look in diamonds has been very popular,” says Eve Goldberg, co-owner of William Goldberg Diamond Corporation, which produced the custom-designed ring. “It’s a very elegant cut and it has an old feel to it.” As for the stunning center stone, the jeweler says that Ashoka stones are rare, with less than 10 percent of rough diamonds each year having the potential to be cut in this unique way, with 62 displayed facets and rounded corners to create a dazzling sparkle–just like Reese’s eyes when she saw her ring, no doubt.
