Blue topaz jewelry is used to celebrate the 4th wedding anniversary. So, in case your 4th wedding anniversary is near, you can plan to gift your spouse a beautiful blue topaz ring or perhaps a blue topaz necklace. Also, the blue topaz gemstone is the lucky birthstone for the people born under the zodiac of Scorpio. Although blue topaz is not categorized as a precious gemstone, still in terms of durability, it is as good as the big four (diamond, sapphire, emerald, and ruby) with the plus point being, that it's much cheaper.
