I have attached a number of files that provide and idea of look and feel for artistic direction.
The overall feel is magical/mystical without looking like its trying to hard or not authentic.
The primary colour palette is emerald green, black and white.
Ideally the logo will be reversed out of black, yet it also should work on a white background.
The font suggestion for the word 'Emerald' is Merlin or Mystical. Yet the font should look like a cut emerald stone, similar to the image emerald stone attached. Preferably in caps.
The font suggestion for the word 'Essence' is Valerio or a beautiful, easy to read script that is feminine. Preferably in caps/lower case with the tail of the letter 'e' extended and ending in a splash of sparkles.
I also attach a file that gives an idea of the initial stacking of the words. Yet in should also work side by side.
