I can’t express how amazing Pano and Cathi were with helping me find an engagement ring. They walked me through the entire process with care and patience. I ended up learning a lot, actually! They also managed to get everything done in a short amount time and for that I’ll always be grateful. My fiancé gets a lot of compliments too. Please consider paying them a visit for your jewelry needs!

Pano did such a lovely job on our wedding bands. They are exactly what we wanted and we plan to go back to him for other pieces in the future. Pano and Cathy are simply lovely people who are a pleasure to do business with.

Pano beautifully restored a ring passed down to me that has a lot of sentimental value. It may not be worth much money but it's worth a lot to me, and he did an amazing job restoring the prongs that had worn away. Kathy helped me to find a cross for an upcoming baptism, one that would suit a Greek Orthodox ceremony. Working with them was such a pleasure and I will be back whenever I need anything fine jewelry related!

Custom Jewelry FAQ

In our design meetings with you we will discuss possible designs that you like. We then guide you in the material selection to make sure the piece of jewelry fits your personality and taste. If the piece is a gift then we’ll help you match it to the recipients taste and style. We will help you envision the final piece so you can make the final decision on your new custom jewelry. We will then help you decide on precious stones for the jewelry by having a selection of gemstones available. These are as unique as your custom designed jewelry will be!

Next we’ll provide you with a breakdown of the costs and then get started to produce your new piece of jewelry after your approval.
