Mary-Kate Olsen Looking for Pricey Engagement Ring

The fashion designer is reportedly checking out Neil Lane rings to marry boyfriend of a year, Olivier Sarkozy.

Mary-Kate Olsen is taking her relationship with her much older boyfriend Olivier Sarkozy to the next level. Rumor has it, the former child star has been spotted shopping for an engagement ring in Los Angeles recently.

The 27-year-old fashion entrepreneur has been dating the 44-year-old banker for more than a year. Their age difference had been the subject of chatter, but Olsen defended her choice, telling Wall Street Journal last year, "Everyone has an opinion. I find it's better to focus on what's in front of you and to keep putting one foot in front of the other."

Looks like Olsen is getting serious about them. Spies told NY Post's Page Six that she visited Neil Lane boutique in mid November and has since returned to the store to check out some blings. "Mary-Kate has been seen several times in the last three weeks checking out huge engagement rings at the Neil Lane store," the source said.

Olsen has a particular taste for the pricey jewelry. "She really likes cushion-cut diamonds, and all of the rings she has looked at are over 5 carats," said the source. “She has narrowed it down, but still hasn't made a final decision." She even reportedly considered rings that has the price tag over $100,000. "I don't think price was an issue," another source said.

Page Six noted that Olsen was always alone during her visit to the store. Representatives for Olsen and Neil Lane have not responded to the allegation.
