London — When the world tunes in to watch the coronation of Britain's King Charles III on May 6, there may be a lot of eyes focused on what the monarch is wearing. The eco-minded king has decided to reuse several historic items on the big day, including some robes literally made of gold.  

"His majesty the king has decided to reuse pieces from the coronation of his grandfather, King George VI, in 1937," Caroline De Guitaut, Deputy Surveyor of the King's Works of Art, explained to CBS News.

• What is King Charles III's net worth?

Clothing the king for his big day takes precise planning, and that means readying the Coronation Vestments, including "two of the most significant pieces worn by the sovereign during the investiture" portion of the ancient coronation ceremony, said De Guitaut, showing off two golden robes that "haven't been worn for 70 years."

• The schedule, and how to watch King Charles' coronation 

When King Charles is crowned at London's Westminster Abbey, he'll wear the same royal robes that his mother, the late Queen Elizabeth II, donned for her coronation in 1953.

A glittering, embroidered robe made of gold silk, called the Supertunica, will be worn under the Golden Imperial Mantle, which was first made for King George IV in 1821.

"It is woven from cloth of gold and embroidered with goldwork embroidery to a design which has a strong tradition," said De Guitaut.

The monarch was determined to make his coronation as sustainable as possible, and other historic items have also been dusted off and restored for the occasion.

"We've got this wonderful, sustainable, eco-friendly king who's reusing something rather than having a new glove," said Deborah Moore, CEO of Dents Glovemakers.

Charles will wear the same coronation glove used by his grandfather nearly a century ago.

De Guitaut explained that the glove would be "placed on the king's right hand during the investiture" on Saturday.

The king will also reuse his grandfather's sword belt, which will be placed around the Supertunica.

The golden robes weigh about 13 pounds together, and the king's 9-year-old grandson, Prince George, will help carry them through Westminster Abbey as Charles walks to his throne for the crowning moment.
