It’s been a while since I’ve done one of these so I thought I’d bring up one of my favorite topics... the wrong things people say about jewelry.
Diamonds can’t break because they’re so hard.
Wrong! Ask any jeweler who’s broken one - they’ll tell you different. Here’s the real story. There is a difference between Hardness and Toughness. Hardness is a stone’s resistance to scratching or abrasion. A diamond is the hardest natural material on the planet. The only thing that can scratch a diamond is another diamond. On the other hand, Toughness is a stones resistance to breakage or cleavage. A diamond, because it is so hard, has a relatively poor toughness. You can bump a diamond (hardness 10) into the corner of a glass showcase just right (hardness 6) and break it clean in two. Let a pair of pliers slip just right while you’re setting a diamond and you’ll break a chunk off before you can say Uh oh! And for the record, every diamond substitute to date will scratch glass.
