About the Jewelry

This pendant was made with a square piece of a silicon wafer. The wafer has multiple chips on it. Included is a micro-photo of a 1x1mm section of the wafer (see picture). This wafer was created with test chips on it. These custom logic test chips were made in the mid-1990s. The various types of computer chip test circuits allowed the maker to verify that the manufacturing process was working correctly. These test patterns can make some of the most colorful silicon wafers. The circuits are created to test various standard circuit types. By creating known circuits with known behaviors, the manufacturing line can be tested for any functional problems. Because only a few test circuit wafers are needed, these are some of the most uncommon chips.

Included in the resealable bag:

The one-inch square pendant (since these are handmade yours may look slightly different than the one pictured here, but satisfaction is guaranteed), a  bronze 24" necklace, a closeup picture of the chip (see pictures) and a ChipScapes card that gives information about this jewelry (see picture).
