It was a great show and we met many new customers as well as many return customers. I was also invited to present a necklace we made to show people what can be done with AU gemstones.



Lambert donated toys and money to the Good Shepard Sisters care center in Bangkok

Giving the toys and watching the Xmas show they put on for their donors. It was an uplifting experience to see so much good being done and being a small part of it.
