There is an endless bounty of eye-catching gemstones throughout the world and this spectacular boulder opal is one unique beauty that looks like a shimmering crystal encased in a tree fossil. Its opalescent sheen seeps through the cracks of the seemingly wooden rings in lustrous hues of emerald green and aqua blue. Like something out of a fairy tale, the triangular piece radiates through an organic pattern mimicking the growth rings of tree.

In a remote location in rural America, a photographer has discovered a rather unique gathering: row after row of presidential busts. Like a zombie graveyard, the field contains 43 gigantic sculptures, ranging from Dick Nixon and FDR to JFK and Honest Abe. The likenesses weigh between 11,000 and 20,000 pounds, with some standing as tall as 20 feet. Almost all the busts are cracked, crumbling and worn by the elements, adding to their eerie appearance but not preventing the presidents from being recognizable at first glance. Here: Abraham Lincoln in front of presidential busts. (Photo by David Ogden/Caters News)

“Potholes” is a series of photographs depicting the concave street cracks and holes as a collection of imaginative tableaux in the city. Captured within the backdrops of New York City, Los Angeles, Toronto and Montreal, the sets explore the urban flaws as a playground creating a multitude of uses out of the potholes. Directly engaging the street and the city, the highly imaginative series transforms the bad into good, creating a tongue-in-cheek collection that is at once contextual and surreal”.
