Founded in 1973, in Hermosa Beach, California under the name of Zango Bango,

we started business in a small co-operative of artists and master craftsmen.

Our quality, style and designs set us apart from the normal types of jewelry offered by the

mass produced and mass marketed jewelry stores and manufacturers of the time.

The business grew with worldwide advertising in magazines like Easyriders and Iron Horse.

A large and loyal following of satisfied customers made us a recognized name in biker jewelry.

Unfortunately, circumstances arose and we decided the best thing to do was to close the business.

After many years of sitting idle we have been reborn as BlackHeart Metals. We are still located in Southern California where we have a small shop and our master craftsmen make all our products by hand. At BlackHeart Metals we strive to bring you the highest quality hand made Sterling Silver and multi metal products. Master craftsmen create all of our products with a focus on quality, detail and care. We make our own designs, molds, castings, and fabricate our own necklaces, bracelets and wearable art.
All of our rings are made to order; we do not mass produce or outsource any of our products. This may mean that your ring size or specific item is not always in stock when you place your order, but please understand that our master craftsmen will make your items in only a few days. This process helps keep our prices down by lowering the amount of stock we must maintain, while giving you a custom fit.
If you do not know your ring size, use our handy ring sizing guide, which will help you through the process, to give you the custom fit you deserve. Our necklaces and bracelets are individually made by hand, and can be made to custom lengths, at your request. Most of our products can be made in 14kt gold, but due to the market fluctuation in the price of gold, we will not be able to post prices on our web site. Please contact us to obtain a quote for the item or items you would like made in gold. Make sure to include your ring size, length of necklace or bracelet, etc, so we can quote you the most accurate price.
