Full Moon is a washed up cream and grey granite cobble from many moons ago.
This product may have pieces larger than 8" as it is not a handsorted material. It is expected that about 90% of cobble will fall into the 4" to 8" range. Larger cobbles and rip rap are typically run through Grizzly Screens. Read more about that process here: https://www.decorativestonesolutions.com/news/learn-the-3-ways-landscape-rock-is-sorted.
The Full Moon Cobble can be found throughout Southern California set in mortar off freeways, in medians and also used as loose ground cover. Installed it tends to have a creamy look with salt and pepper. As a product of nature, it is normal for this material to range from a creamy tan and beige to a salt and pepper.
