45th anniversary FAQ
What is the gemstone for the 45th anniversary?
The 45th anniversary gemstone is the sapphire — unlike most years, the lists agree without variants: the forty-fifth is the sapphire anniversary. Blue sapphire is the classic choice, and its historic meaning, fidelity, fits the year exactly.
Does a 45th anniversary sapphire need to be deep blue?
The classic is a rich royal blue, but no rule requires it — sapphire comes in pink, yellow, peach and padparadscha. A lighter cornflower sapphire often costs less and glows more in daylight; depth of color is a taste decision, not a tradition.
