I would probably say the 5MM. (Not knowing the length of your chain.) My Reasons are that ropes always look bigger than flats. A 5MM diamond cut rope and a 5mm link chain look very good together in my opinion. I also picked the 5MM due to your use of a pendant. You could wear the pendant on either your new rope or your curb. The 6MM rope would look a lot bigger than the 5MM curb in my opinion, but if you weren’t doing a pendant, I would say if you chose the 6 mm at a longer length then your curb, it would be dope. As for the 5MM rope, you can wear it at the same length as your current chain or longer. I personally like a 4MM rope if wearing shorter than your flat. These are just my opinions and the greatest thing about jewelry, is that it’s expressive and each look is exclusive to that person. I would say if you haven’t, looked up the channel, “JewelryFromADistance.” He has a video on this very topic that you may find extremely helpful. Thank you for commenting and watching. Stay Blessed!
Holy crap! I bet! The 8MM to me is an amazing size looks wise! I know that it would be too heavy for me, but the look is amazing! Especially with that 1 oz coin! Thanks for watching/commenting! Stay Blessed friend.
