Happy April 1st! We have a new month and a new gemstone to celebrate! April’s gemstone is diamond and in honor of diamonds, let’s take a peek at a famous diamond diadem.

The Royal Collection Trust refers to this tiara as the Diamond Diadem. These days it is worn by Queen Elizabeth II when she attends the State Opening of Parliament, but it was made in 1820 by Rundell & Bridge for George IV.

This diadem is in the style of a crown and set in silver and gold. There are 1,333 sparkling diamonds to admire. Two narrow bands are completely set with pearls.

The diadem has four crosses; the center of one of the crosses is set with a four carat yellow diamond. There are also four sprays that represent the national emblems of the United Kingdom. Even though the diadem was made for a king, every queen and queen consort has worn it after George IV.

If the diadem looks vaguely familiar to you, it’s probably because you might have seen it in portraits of Queen Victoria. You may have also seen this diadem worn by Elizabeth II on postage stamps and coins.
