You don't have to be rich to collect art jewelry though. While it might be tempting to believe that a collection doesn't count unless it contains unique and important pieces from well known makers, it is entirely possible to put together a collection on a budget that covers many influential modern art jewelers without breaking the bank.
The first trick to collecting on a budget is to identify work that you enjoy. I think the idea of collecting work only because of it's perceived value by other collectors and formal institutions like museums is nonsense- collect first for yourself.
Secondly, consider your budget. You can make several small additions from an artists (or several artists) by selecting from production lines instead of one of a kind pieces. Production lines have the added benefit of often being more wearable work, as that's usually what they're intended for. A well rounded collection of pieces from production lines is not to be scoffed at- it presents an accurate picture of the art jewelry world as a sphere that actually supports artists in their daily practice, while a collection of one of a kind pieces presents a picture of the higher ideals and art aspirations of artists.
If you're looking for an idea of where to begin, I'd recommend viewing images of art jewelry online. As part of my own gathering of inspiration and connecting with other makers, I curate a Pinterest board of art jewelry, which I invite you to view by clicking below!
