I have a diamond ring last year in september..... the diamond set inside the ring (flat with the ring surface)...... 2 weeks ago i carelessly knock my ring on my drawer (wood).... and the diamond is loose so I took it back to the jewelry store and ask them to fix it for me.... and the jewelry guy told me that the diamond is chipped alittle on the side of the diamond (hard to see if it's in the ring) O_O i was so surprise... I thought diamond is the hardest thing in the world... how can it be chipped by just hitting it on the wood.... I'm so pissed anyway.... Is it possible for the diamond to chip if I hit it on the wood?????? I'm confused!!!
