Hey, that’s our favorite. To celebrate the transition into freshness and spring we have selected a stunning palette of colored diamonds for you to browse. Colors range from the rainy grays of April showers to the soft greens of new shoots and dewy buds. The word diamond comes from the Greek word adámas meaning "unbreakable.” FYI the colors in diamonds appear because of trace minerals that become trapped in between the layers of carbon as the diamond crystals are forming deep within the earth. Some diamonds are 3.3 billion years old, making them the OLDEST THINGS ON THE PLANET. Older than the continents.
