When we were in India last year, we visited a semi precious stone museum, and when we were in Beijing we learnt all about Jade at a museum there, so it goes without saying that the girls and I jumped at the option of visiting a pearl one! I learnt so much about pearls I never knew and I know for sure that Bailey will always know the difference betwene real and fake as you rub them together and if smooth = fake and if rough/sandy = real. Some people (aka Bailey) got to test this out as you can do this against your teeth too!
Also we learnt about how to judge a pearl in value, similar to diamonds one must consider the shape and the size and then also the shiner and the smoother, the better. And then afterall that knowledge, I declared it was time for the girls and I to shop!
