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.

Inmates sleep on the steps of a ladder inside the Quezon City jail at night in Manila in this picture taken on July 21, 2016. There are 3,800 inmates at the jail, which was built six decades ago to house 800, and they engage in a relentless contest for space. Men take turns to sleep on the cracked cement floor of an open-air basketball court, the steps of staircases, underneath beds and hammocks made out of old blankets. (Photo by Noel Celis/AFP Photo)

New Jersey based artist, Joe Iurato creates art using hand-cut paper and spray paint to make small wood cutout figures and placed in public spaces. According to Iurato, “a puddle can become a lake, a small crack in a cement wall can become a magnificent climb, a planter box can become a place for a child to play, and a shadow might be a tangible space for a few seconds a day”.

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.

“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”.
