I would make this fun and play up the butterfly theme with different colors of butterfly.
Butterflies are whimsical, and everyone knows butterflies come in different colors. No two butterflies are exact, they are all different; each butterfly is a beautiful and colorful unique work of nature.
I'm not a butterfly gal at this point, but if I were, I would be sure my butterfly earrings do not match!

I would want different butterflies on my ears. I think that's the beauty of this collection, and it reflects the uniqeness of butterflies and you. Two matching pave butterfly earrings are nice, but matching butterflies are a bit expected. Non-matching butterfly earrings are magical. Non-matching earrings would would also be consistent with the non-matching butterfly theme in your ring.
For earrings, I would get the Pave Diamond and Yellow Sapphire earrings. It will be a nice compliment to your Pave Diamond and Pink Sapphire ring. In both pieces (earrings and ring), one butterfly is diamond pave, and the other butterfly is a colored butterfly. It stays in the diamond/colored gemstone/butterfly theme.
The downside is if you did not like the pink sapphire on your ears, my gut is you will not like yellow sapphire either. Yellow stones can be hard to wear near the face.
If no yellow sapphires, then plan B...
I would SO earrings, but with one butterfly being the diamond pave (as in your ring) and the second butterfly being WMOP.
This would still follow the "one diamond butterfly, one stone butterfly" theme. Basically, I would ask VCA for the RG MOP and pave ring, but made into earrings. I would not get the all MOP version as I think it might be a bit boring when worn with your pave/sapphire BTF ring. I think you need bling in at least one ear. Plus, the rule is no matching butterflies...


each butterfly needs to be unique!
Here are two photos to help visualize. The photo on the left is the RG ring, but visualize that as a SO made into earrings. The photo on the right is your ring.
The look will be butterflies floating around, each butterfly being different, as nature intended.
Just my two cents. I hope this was helpful. Good luck!
