Molly Sims didn’t leave much to the imagination when she wore this diamond-studded swimwear for Sports Illustrated’s infamous Swimsuit Edition in 2006. Of course, what the bikini doesn’t actually cover is obscured by misdirection as the swimsuit, the most expensive bikini in the world, is as eye-catching as the woman modeling it.

Designed by Susan Rosen with Steinmetz Diamonds, the bikini is made up of 150 carats of flawless diamonds—including a pair of fifteen carat, round-cut diamonds; a thirty carat, emerald-cut diamond and a pear-shaped, fifty-one carat diamond. Rather than using cloth to make the expensive swimsuit, Ms. Rosen opted to make it out of platinum.

Including the top, bottom and necklace, the world’s most expensive bikini is valued at $30 million. Considering its value, it’s questionable whether or not it can actually be called “swimwear.” After all, who knows what a dip in the ocean could do to all those precious gems?
