As you can see, RBL Teal is much darker. Probably a good 3-4 shades darker and has more of a green hint to it than the Julep one. Julep Jamie was part of the Summer 2011 collection and is described as an ultra-saturated, dark turquoise. It seems to be sold out, but since it was taken down due to being part of last months maven box, it might be just not back on the website yet.
