**Will entertain all offers!** Putting out feelers for this set. I would rather them sell together but willing to sell separately to get them sold! E-ring is .82 ct, AGS, K VVS2, and medium blue Fluor! One of THE BEST K’s I’ve seen! Don’t let the color scare you off! Both rings are 14k and size 7 3/4. Both are low profile and 1.5 mm wide. Both are half eternity, so if you need them to be sized, I’m sure it wouldn’t be an issue. The setting/band were purchased through BlushKarats on Etsy. If you have an offer for the band or Ering separately, feel free to email me. Set has barely ever been worn. I just don’t reach for it. Pictures are horrible, so if you need a video or better close ups please feel free to reach out! Ering is amazing and is white for its grade! I have sold here many times and have been a pricescope member for years. If you are looking for an affordable knock your socks off ering/band set, this is it! Looks way more expensive than asking price! I will pay for priority shipping within US only. PayPal FF or goods and services, but I will ask you cover the fee. No returns as this is a private sale. Thank you!
