About Us


Erinn LaMattery is an independent jewelry designer living in Japan with her husband, youngest son and 1 grandkitty. She stays busy in her little studio surrounded by nature and fills her days with creating, contemplating and a little bit of cleaning.

Located in the hills of Wakayama, Japan, Off on a Whim is surrounded by the peace and quiet of beautiful countryside. Our little studio stays busy and productive as we work on creating custom orders, working out new ideas, dreaming about what to do with our stone collection, and all the other things that come along with life.

Our focus is on staying as natural as possible, using genuine stones and gemstones, real metals and materials. 

Our stones are sourced from a local wholeseller who has put the stones through quality testing, assuring us we get good value at a good price. Our metals and leather supplies largely come from the States.


Our creations are handmade in the studio upon order, so that each order can be customized to the customer's size and specifications. None of our pieces are mass produced or outsourced to another facility.

Our business was built on custom designed pieces, working hand in hand with customers to create jewelry and gifts that capture their ideas and put them into solid form. From the idea stage to the design, tweaking, communicating, finishing then shipping, we aspire to truly make each custom request a piece to be proud of and an actuality of the original inspiration and dreams of our clients.
