Pure sapphires are more expensive than diamonds.
The myth about a diamond’s high value appeared only recently in the 20th century thanks to the De Beers company’s marketing specialists. The slogan “A diamond is forever” was introduced in 1947, and Marilyn Monroe became its face. The high price of diamonds is connected with absolutely nothing. But sapphires were cherished even in ancient Persia, they’re still very rare and precious stones, and their price can be way higher than the price for a diamond.
