Platinum Diamond Brooches

Price guide to antique and vintage platinum and diamond brooches.

Archaeologists have discovered traces of platinum in the gold used in ancient Egyptian burials as early as 1200 BC. However, the extent of early Egyptians’ knowledge of the metal is unclear. It is quite possible they did not recognize there was platinum in their gold.

The metal was used by pre-Columbian Americans near modern-day Esmeraldas, Ecuador to produce artifacts of a white gold-platinum alloy. They employed a relatively sophisticated system of powder metallurgy. The platinum used in such objects was not the pure element, but rather a naturally occurring mixture of the platinum group metals, with small amounts of palladium, rhodium, and iridium.
