If you ever wanted to wear houses on your finger, now’s your chance (though it’s hard to imagine that any sane person would have such a desire)! Clive Roddy offers you an opportunity to fulfill your dream of having a ring that features houses, waves, mountains, or trees. In order to create these rings, first the metal is cut using a laser, and then the whole thing is hand painted using colored enamel. Though these rings are very pretty, it is hard to imagine someone wearing such a ring on everyday basis. These types of rings should probably be reserved for special occasions or festivals, rather than for everyday use. (Photo by Clive Roddy)
