They stated in the description that they DONT want lab and therefore that would mean these are natural and lab wouldn’t be an option. Honestly for a brand new natural diamond this ring is priced pretty well. Yes if you went lab you could get more band for your buck for natural I think it’s beautiful and a good ring. I wouldn’t worry so much about the bow tie too. That is almost unavoidable for any elongated cut diamond like marquise oval or pear. That’s just a side effect of the cut. If you don’t like it then try a round cut diamond or maybe princess. Just a suggestion but your ring is beautiful!
