Necklace made of drilled rough low-quality light brown (Coffee diamonds) diamonds. The stones range from 2 mm to 3,5 mm and weighs a total of 15 carats. Made by a Danish jewelry workshop. The necklace is twisted into three loops. Photographed in both natural and UV light on a black glass plate, and combined into a photo montage. Studio photograph made in Tuntorp, Brastad, Lysekil Municipality, Sweden.

"Speed effect" added to make the image more interesting than just the normal side-by-side comparison, but also to help guide the eyes between the individual stones to see the different colors. See more info below.
