How To Quality-Mark Precious Metals

Here's how to make sure your customers know what they're getting . . . on the day of the sale and for years afterward. Customers feel more confident and appreciate the openness when you take steps to ensure that they know what they’re getting when they buy any precious metal from you—it builds a priceless trust in your business. Jewelry made from wire, sheet or casting pieces with a definable precious metal content can be legally stamped with that information as well as with your maker’s mark.
Be sure to put these designations and your maker’s mark on the platinum, Argentium, sterling silver, fine silver, gold-filled and silver-filled jewelry you sell. Customers will know that you care about and guarantee their precious metal purchases.

How To Choose and Use A Marking Stamp: Bent vs. Straight

Confused about which marking stamp to use? Here is a quick how-to on the differences between bent-shank and straight-shank marking stamps and how to use your stamp to get the best result for every piece, every time.

Beware, if you are new to using marking stamps; you should not expect to buy your first stamp, grab any old hammer and *POW* whale away on one of your beautiful finished pieces of jewelry. For best results, we highly recommend practice, practice, practice and more practice. Use scraps of inexpensive sheet as well as brass practice ring blanks before attempting to mark one of your designs. The mark cannot easily be erased and redone and must be done right the first time.

Also, stamping should be done on work before any stones are set to avoid the damage, misshaping, cracking or loosening of the setting and/or stone that can be caused by the sudden stress of the hammer blow. For best results use support such a bench block or an anvil and a brass mallet to strike the stamp.
