“The sapphire - the gem of autumn, the blue of the autumn sky - is a symbol of truth, sincerity, and constancy,” writes Kunz in his book The Curious Lore of Precious Stones. Blue sapphires have symbolized royalty and divine power for centuries from the ancient Greeks and Romans to the present-day British monarchy. Sapphires boast a Mohs Scale rating of 9, giving them impressive durability and scratch-resistance for a lifetime of beauty and enjoyment. Sapphire is perfect for jewelry for all occasions, including that “something blue” for your wedding day.
