When Kate Bosworth accepted boyfriend Michael Polish's marriage proposal she also scored herself some major bling!

Unveiling her square-cut diamond via her WhoSay page, Bosworth, 29, thanked fans and friends for their kind words during her and Polish's happy time. "This photo was taken by my husband-to-be," the Straw Dogs actress tweeted Tuesday. "Thank you for all the wonderful engagement wishes. . . . We feel truly blessed."

Bosworth and her director beau, 41, who met on the set of Big Sur (due out later this year) made their debut as a couple at a Coldplay concert in August 2011 and confirmed their engagement one year later.

"On our first day in Seoul, my fiance, Michael Polish, and I venture out to discover Changdeokgung Palace," Bosworth wrote in a Vogue travel blog, before continuing on with her chronicle of their visit to South Korea this summer.

It will be the first marriage for Bosworth, who dated True Blood's Alexander Skarsgard for two years before calling it quits in July 2011.
