Perhaps it didn’t look right next to all her other bling?
The actress, 29, was sporting a load of Tiffany & Co. jewelry, including a stitches diamond ring in platinum and 18-karat yellow gold (designed by Jean Schlumberger, worth $25,000), as well as five diamond metro band rings set in 18-karat yellow gold (worth $1,900 each).
But her left ring finger was bare, with no sign of the custom-designed ring that Timberlake, 30, reportedly proposed with in Montana.
Biel also dazzled with two other notable Tiffany pieces – round solitaire diamond stud earrings set in platinum, 6.12 karats (worth $243,000), and a round diamond daisy opera length necklace set in platinum (worn down her back and worth $135,000).
And worth noting: On Friday, the actress stepped out for W magazine’s best performances party at Hollywood’s Chateau Marmont and was without a ring on her left finger then, too!
