So there you have it, white sapphires are the most natural, hard, rare gemstone that are second only to diamonds. Though not imbued with the same properties or “fire” as a diamond, they are more affordable and are therefore more attainable in larger stone sizes with pristine clarity that can be designed with custom cuts. White sapphires also don’t come with all the trappings of diamonds and can be a conversation-starter with a unique story.
