In the spirit of the season, today’s post is a little bit Fan Art and a little bit “Here’s an idea if you’re looking for a gift for the Brent Weeks fan who has everything.”

Brothers Stephen and Tim Challener cut a gemstone to look like yellow luxin! It’s hard to capture how beautiful it is–and in the evening light, it looks like it’s glowing. Stunning!

They had this to say about these special gems:

“We call these stones ‘yellow luxin’ because they have an uncanny glow to them, like the magical gemstone in the Lightbringer series by Brent Weeks. He was kind enough to let us use the name, which is incredibly nice of him. In the Lightbringer series, perfect yellow luxin is an indestructible material made out of yellow light, which glows in the dark and can be used to fuel other magics. In our world, this is a rare type of synthetic garnet – a cerium-doped yttrium-aluminum garnet currently used in lasers, LEDs, & x-ray detectors. It is one of the most fluorescent crystals that can be manufactured – and most of the more fluorescent ones, like NaI:TI (we Googled it for you: sodium iodide doped with thalium), are extremely soft and don’t like water. This synthetic garnet will happily turn just about any light in the spectrum above yellow into yellow light. This gives it a very uncanny glow, particularly under indirect sunlight. Your eye tells you something weird is going on, because the stone is more yellow than it should be – it’s like it’s Photoshopped into real life.”

They have an appropriately successful (which is to say, flourishing) store on Etsy, with rough and faceted gemstone necklaces, rings, and earrings. There’s an impressive collection of beautiful and unique stones, many of which they mined themselves. They also have an Instagram page, which features their jewelry as well as some beautiful images of light captured by the gemstones. Gorgeous work, guys!
