Selfridges is stocking a newly released line of LEGO jewelry for adults, in the form of sterling silver rings featuring the iconic construction block.

They sell for £50 ($76) and come with interchangeable bricks available in 15 colors. There will also be a range of charms to accompany the rings.

"In our research we found that LEGO is one of the most tactile objects for people of all ages. You just can't resist picking it up and starting to have a play," says a Selfridges' spokesperson.
