This attempt at a switcheroo didn’t fool the police.

A New Jersey woman was charged with theft this week after allegedly stealing a $2,000 diamond ring from one Costco store and then swapping it for a $28,000 sparkler at another.

Store managers then determined that the ring Kolano gave back was a $2,000 one swiped from a Costco in Wayne earlier in the day, Fox 5 NY reported.

Clifton police tracked Kolano down at her home in Nutley and found the $28,000 ring buried under a dirt fence along the Passaic River.
