Reese Witherspoon's fiancé, Jim Toth, went out of his way to find a unique engagement ring to accompany his proposal.

PEOPLE reports that Toth, 40, gave his future bride-to-be a 4-carat Ashoka-cut diamond set on a diamond-and-pavé-adorned platinum band.

The ring was custom-designed with Toth's input by jeweler William Goldberg of the William Goldberg Diamond Corp. Goldberg told US magazine that Toth was drawn to the uniqueness of the vintage-style Ashoka cut, distinguished by 62 displayed facets and rounded corners.

Just 10 percent of rough diamonds have the potential to be Ashokas, making it a sentimental choice for the bride who has everything.
