Laurie, may I make some suggestions on that 2nd setup?

1. reflection color looks okay, somewhere BB recommended (255,215,150) for red gold and (255,230,95) for yellow gold.

2. I suggest to set the specular color to the same value. Specularity is just the reflection of direct light, and metals produce colored reflections (gold: 100% red 95% orange 30% blue)

3. I suggest to improve in the fresnel. Set Inner color to 95% white because that matches gold, the outer color is 100% (full reflection due to fresnel effect). The IOR should be very high for fresnel on metals, say 40 but 10 at least. 1-4 is for liquids and glass and stuff.

4. I suggest to match the reflectivity of the reflection and the one in Blinn. Feeding the fresnel into the blinn as well seems logical then, for the reason mentioned in 2.

have fun

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
