Going to put the dark orange/red Zircon 2.78 ct 8.13mm round cut into a setting like the ring on the right but with a thicker band and larger prongs for the larger gemstone. I'm also going to be adding white gold to the design, the part with the 3 bumps on it that twists up to be a prong is going to be in white gold on both sides of the ring.

The gemstone in the ring on the right is a round cut Mexican Fire Opal at 0.85 ct and around 5 to 6mm I don't remember the exact size.
