Oooh, I think your scalloped pearl idea is incredibly elegant and I want to see more of it in this necklace! I agree with smokingmoneky...the straight lines with the curves just strikes me as a little off (although if I were to see it worn during a wedding I wouldn't bat any eye. But here in a critiquing environment...) I think another row or two of what you've already got would be really pretty. Maybe something like this?
I apologize for this rendering but you get the idea.
WOW!!! That's what I had originally drawed out. (along with about 20 other drawings) Creepy!!! But, I really like that little bit of "sparkle" that the teardrops give it, which is why I put that idea to the side for a little while, but hadn't totally ruled it out. Thanks for your suggestions.
What if you added the extra scallops then hung just a single teardrop from the middle of the bottom one?
