The entire concept is the "G" for Guarantee with the Flask reversed White out of the top curve and the Microscope Positive Dark out of the bottom curve.
Not sure how it would translate and it might look like all the others unless I come up with something different ... I'll try it!
Just posted a new one for you. Better than I thought.
The flask being in the background (lighter color) and not overpowering - - helps frame the microscope, making it special. The flask also supports the idea of a Lab tested product.
