Before you come in, here are three things that will help make your engagement ring experience even better! 💍

Let’s get into it ⬇️

1. Inspiration photos

Whether you are just beginning your search or you have already been exploring styles, it is always helpful to bring in inspiration photos of what you are dreaming of. Seeing what you are drawn to gives us the perfect place to start designing!

2. Personal style

Your engagement ring should fit seamlessly into your everyday life. Considering certain aspects of your lifestyle like how active you are, your profession, and the type of jewelry you typically wear, helps us design a ring that is both beautiful and practical for you.

3. Price Range

We always respect both your time and your investment. Having a price range that is comfortable for you helps us curate a selection of diamonds and setting prior to your appointment, so that every option aligns with what you are looking for

⭐️ Of course there is no need to worry if you don’t have this all figured out yet, that’s what your appointment is for!

However, a little preparation goes a long way in creating a ring that you will love forever 💍✨
