Fabulous natural necklace, and very special as triple strands, I wonder what date these were put together?
I suspect now that golden pearls are so highly regarded, these may go a lot higher than the estimate.
Here's an interesting thought. If you go back to Art Deco cultured strands quite a few had a distinct yellow/golden/green/bronze overtone. However the fashion from 50's/60's onward was for a very white color with pink overtones.
I guess the yellowish pearls become seconds/rejects to be bleached and post treated, meanwhile growers bred/selected for whiter pearls.
I wonder if the fashion had trended towards golden shades back in the early days of cultureds, whether selection and breeding could have produced cultured golden Akoyas that look like these?
