I kinda like this layout. Much lighter, not the chunky, heavy look.
I would like it to be a set of (3mm,5mm (stardust), 3mm beads) between every 2 Tahitian. The Tahitian pearls are approx 9.2X11MM - 10.9X13.5MM
Finished off with a 6mm (stardust clasp), that will be around 26 inches.
I have yet to get the strand, but just to get the idea of the proportion hence the attachment. The sizes are similar (3mm beads,5mm FW pearl,3mm beads and a 12.5mm round)
What do you think

?
Btw, If there is NO knot between the bead and pearl, will the gold bead be rubbing against the pearl and scratches the pearl after some time? Do you advise to do with a knot between the bead and pearl or without? reason being? tks
Btw, Cathy if you are reading, may I know you Tahitian pearl size as well as the gold bead size? They are gorgeous

Tks!
