Many of our pieces, such as those in the Nest collection, are delicate mini-sculptures with only a dab of glue to secure the hand-wrapping. Please treat with care and resist applying pressure on the wire surrounding the gemstones. Ease the backs onto post earrings and handle rings by their shanks. Nested cuffs and bangles should be put on and taken off by touching the metal only. Both sterling silver and gold-filled jewelry need an occasional polish from regular wear (perfume, skin oils and skin ph fluctuations) along with natural oxidation. To shine up your jewelry, you may use silver polish so long as it is safe for stones. We recommend Jewel Brite products. Their tarnish remover & polishing cloth are excellent to use on all metals. Their jewelry cleaner solution is organic, 100% biodegradable, child-safe and safe for all gemstones and pearls. We highly recommend Dawn Dishwashing Liquid & hot water to restore the sparkle to all of your JB jewelry and it's great to use on all of your good jewelry as well. With proper care your JB jewelry will last forever!
