We have a great contender for the November edition of E.S. Eco-Over! If you’re new to this feature, we take a hot trend and find a stylish equivalent from an ethical source — and try to save you some dough in the process.

J.Crew hit a home run with its ubiquitous bubble necklaces this year. This statement bib packs a powerful punch against a little black dress or a strapless gown. But at $150 for plastic beads, we knew we could find something similar (and preferably vintage) on Etsy.

That’s where seller BasilTheCat delivered with her lovely made-to-order version crafted from ivory cabochons she unearths at estate sales and flea markets. (The necklace is also offered in a turquoise color.) She then sets the beads in antique brass on a gold-plated chain for less than a third of the price of J.Crew.

With 1,300 satisfied customers and growing, BasilTheCat is where it’s at for this trend with a handmade spin.
