Platinum was introduced for use in diamond wedding settings in the 1920s. During the 1920s and 1930s, platinum was frequently used in filigree settings because of its ability to withstand wear and tear. Platinum continues to be the most expensive and most valued metal used in jewelry making and is used in contemporary platinum estate jewelry. Estate jewelry made from platinum will usually feel heavier when compared to other jewelry. Estate rings made of platinum will appear to be whiter than white gold.
