No, you do not need to have the perfect idea of what you want for your custom jewelry. We can either start with the type of jewelry you want, such as a ring, necklace, bracelet, earrings, etc.
If you have a specific reason for making your creation such as for an engagement ring, heirloom redesign, personal talisman, gift or milestone, memorial jewelry, renewed vows, or anniversary jewelry, these are great places to start.
If you have a rough idea of what you want or a concept, that is a great beginning to start your custom jewelry journey.
