Symbol for 45 years marriage anniversary

The 45th Wedding Anniversary symbol is Sapphire.

Sapphire is a very desirable gemstone due to its hardness, excellent colour, durability, and luster. In the gem trade, Sapphire without any colour prefix refers to the blue variety of the mineral Corundum. Though, the word Sapphire encompasses all other gem varieties and colours of Corundum as well, not including Ruby, the red variety of Corundum, which has its own name since antiquity.

For the last few months, experts and media have been speculating on whether Apple will use Sapphire displays for its next iPhone. However, the company has now filed a patent application for "oleophobic coating on sapphire" according to AppleInsider. Learn more at International Business Times UK.
