Customer Reviews
Handmade Jewelry and Quality Time with Family
It was enjoyable to be able to choose the type of look we want for our jewelry, to take pictures freely, and to see and hear the jewelry-making process up-close!
Handmade Tree Bark Texture Wedding Bands
We liked how we get to decide on the designs of our rings. The artisans are here to help, but we were able to handle the processes without much difficulty. From this workshop, we were also able to understand how rings are forged.
Handmade Champagne Gold Wedding Bands
We love the experience of forging the raw metal into our ideal ring and making it one-of-a-kind in the world. Moreover, it's refreshing to see the artisans at work—something you don't always get to see.
Handmade Platinum 950 Wedding Bands
It was our first experience making rings and it was so fun! We were touched when the rings started sparkling as we polished them!
