Sapphire
From Giftypedia
The sapphire is the birthstone of September, and the classic gift to give for a 45th anniversary.
Blue considered normal color for the sapphire but it actually can be found in many colors. Other than blue are called fancy color sapphires.
The word sapphire comes from the Latin word “saphirus” meaning blue. It is the second hardest gemstone with a Mohs scale of 9.0. Only topped by diamond at 10.
Often heated to give the stones more clarity and a deeper blue color.
