CTLAWER, I personally would hate wearing jewelry as “safekeeping” and not being the owner…I don’t think it’s right to give jewelry that way. When I bought jewelry for my daughter-in law I only thought if she’ll like it and my husband and I gave it to HER, not for safekeeping.
A diamond is only part of jewelry we buy for kallahs. The bracelet, earrings, diamond setting, and pearls, cost much more than a diamond and to buy it to have “for financial emergencies” is not a good idea. Most kallahs will sell their jewelry after 15 years because of changing styles.
If you invest in diamonds only, that’s like investing in gold only. Buying diamonds does not mean buying jewelry, diamonds itself are not jewelry pieces. And I believe that genuine diamonds will drop in value once genuine, lab created diamonds will be mass produced. Even deBeers will be selling these diamonds.
