FYI: A Christensen Agate Company GUINEA has a base glass of transparent clear, cobalt blue, or amber. I've heard tales of red or green base glass Guinea, but I've never seen even a picture of either. The surface is covered with varying amounts of colored spots and streaks of the CAC pallete.
CAC COBRAs and CYCLONEs are different names for the same marble. The base glass is transparent clear only with all of the colors swirled together on the inside of the marble, i.e., below the surface. A GUINEA/COBRA HYBRID has all of the features of both the Guinea and the Cobra. DESCRIPTION: The base glass is crystal clear with two cutoff seams on the surface. At first glance, it appears that there is nearly 100% coverage of the renowned spots and streaks, but, in fact, only one side runs from seam to seam with full coverage. Between the seams on the other side, there are plenty spots and streaks, but a rather wide window allows you to see down inside where there is an intricate design of the same colors with as much activity as there is on the surface. The base glass is so clear, its confusing to distinguish the inside activity from that of the surface. CONDITION: MINT 9.4 The surface is wet and shiny, and I can find no signs of play or wear; but with the aid of a bright light and lens, I can see some very tiny, almost microscopic, needle-point size dimples with melted edges, some with dark-looking debris in the bottom. With the melted edges, it seems clear that they were introduced during the manufacturing process, consequently as-made. You may click here to view the grading system I use. Size 15.81mm or 0.622" at the equator. | |||||
