Enamel pieces abound at all price points but it's not worth even considering the cute Target bangles, which will chip faster than $2 nail polish. I will show the magnificent Tiffany Schlumberger bracelet to show how superb enamel glows. (Price, $31,200.)
Here are two pieces from Beladora; Belle offers such gorgeous vintage choices.
A ca. 1970 bangle, half jade and half enameled silver, with an exotic orchid motif; price, $499. I'm not naming names, but take your $500 to certain jewelers and see what you get. This is from the Beladora2 site.
Belle also has, on Beladora, this soigneé set of woven enamel clip-back earrings and ring (size 5 3/4). Evah so Palm Beachy, at an eminently reasonable $1,250. Jeans, pale blue shirt and these...
I'm showing the detail of the shell on Aurelie Bidermann's pendant; the cyclamen pink pop on an 18 1/2 inch orange cord makes a summer passepartout piece. From Netaporter; price, $79.
The Kate Spade "Idiom" bangle uses epoxy resin (sometimes called "cold enamel".) It's durable, made from the same kind of product you'd use to repair a porcelain sink. This bracelet shows another feature of enamel: you can enjoy a big, graphic piece for a modest cost. Price, $78 from Nordstrom. Mixes well with other bangles, but wear chain bracelets on your other wrist.
Enamel creates a dramatic backdrop for stones. I like these enamel, ruby and diamond hoops, especially the scattered in-and-out setting. On sale for $239 from Buy.com.
Here's a similar one, of silver with green, gold and orange enamel. 1 3/4" across. From Argo & Lehne Jewelers, price, $237.
If you find an enamel piece at a jumble or church sale, snap it up. A bit of crazing (the network of fine cracks) can add to the vintage charm and small chips can be repaired, but stay away from dents and damage to clasps or hinges. (Soldering can wreck enamel.)
Enamel work is under-appreciated by the bling crowd, its aesthetic deeply admired by women who prize artistry over carat weight. Might that be you?
