Tori Spelling's jewelry collection has grown considerably in the past month, and it's all because of her loving husband.

In early May, Dean McDermott, 45, presented his pregnant wife with a gold ring, set with six cabochon corals representing their six years of marriage; the actor and father-of-four collaborated with celebrity jeweler Neil Lane on the design.

McDermott worked with Lane once again to create the perfect birthday gift for his wife, who turned 39 Wednesday: a cabochon cut crystaphase gold and silver ring. "Dean just loves giving her rings," Lane tells Us Weekly exclusively. "He always calls her his lucky charm."

Lane, who has also created baubles for Britney Spears, Emily Blunt and Jessica Simpson, designed McDermott and Spelling's original wedding bands.

Though she's nearing 40, Spelling isn't worried about getting older. "Not a day that goes by that I don't think of myself as 28. I think my internal clock stopped there. But the realist in me says, 'Hey, I've earned those 39 years. Own 'em!' And, it's true!" she blogged Wednesday. "I couldn't be happier with the woman, wife, and mom I've become."

Expecting her fourth child, the Beverly Hills, 90210 alum and mom to Liam, 5, Stella, 3, and Hattie, 7 months, added: "I feel truly blessed with the life and love I've created. So, for my birthday I'd like to give myself a pat on the back, a big hug, and a high five all in one!"
