Two trays and a book.
One tray is stones. The other is settings, bands and stackables. The book holds the rest of them. We sit your stone on top of a setting, put it next to a band, swap it for another one, and keep going until you’re looking at the ring instead of imagining it.
Nothing here is a computer drawing. You’re holding the actual pieces. And if what you want isn’t in the trays or the book, you can still have it — we’re not limited to what’s on the desk, it just takes longer.
