Custom
create something unique
A piece from a chain jewelry store might look good but it doesn’t have that personal touch. When you work with a Mark Peter’s designer, you can create something totally unique.
Custom jewelry isn’t only for the wealthy. Creating a custom piece of jewelry can be great for your budget with typical savings between 20-30%.
This savings allows you to up the carat weight or add a fancy filigree detail.
When you work with us, we will discuss your ideas one-on-one and walk you through the entire process, from start to finish.
We would love to work with you to create the piece of your dreams.
