Photograph a stone to see what it most likely is, learn how Earth formed it, and keep a private record of the stones that matter to you.
Free to start. No ads. For iPhone and Android.
Photograph a stone to see what it most likely is: minerals, rocks and common imitations. When the match isn't clear, you see up to three candidates beside our own reference photographs.
A photograph gives a best match, not a lab test. You can Snap before you make an account.
Earth forms every crystal, through heat, pressure, water and deep time. Every stone in the catalog has a page, and each part of it is labelled for what it is:
Traditions describe what people have believed, not medical effects.
An Encounter is guided time with one real specimen. You look closely, learn how Earth formed it and how to care for it, and bring your own meaning to it.
Two Encounters are free: Amethyst, and Time inside matter, about azurite becoming malachite. First Encounters adds three more: Amazonite, Labradorite, and Limonite after Pyrite.
My Ledger keeps your stones, the ones you own and the ones you hope to find, with your photographs and notes. Export it whenever you like, free.
A Reflection is what you noticed, felt or questioned about a stone, or that you felt nothing. Feeling nothing is a perfectly good answer. Only you see your Reflections.
In the lab you start from a specimen and set conditions the way Earth does. Each condition narrows which minerals could form.
Then you make a Creation: a generated film of your stone becoming another, labelled as art. Azurite and malachite show the real change it draws on, where malachite replaces azurite over time.
Place a Creation at a real spot, through your camera, for someone else to find, and pick up drops near you. Drop alerts wait while you're driving, and you can report a drop or hide someone's drops.
Your Constellation is the shops whose drops you've picked up.
The hunting grounds are places in the United States where the public may legally collect minerals, by state, with what you can find there and each place's own collecting rules. Each is shown as an area with a safety note.
I'm a scientist and an engineer, and some of my favorite conversations are with people who love crystals. They tell me what they notice in a stone and what it means to them. I take that seriously, and I won't fake evidence to do it.
So Crystal Ledger keeps things in their places: what we saw, the science of how Earth formed the stone, what people have believed about it, and my own view, each under its own label. Your Reflection is yours.
Every stone carries a material history. Learning its name, its story and how to care for it is a way of paying attention.
Traditions describe what people have believed, not medical effects.
Shops can place drops on the map with their name, make offers redeemed at the counter, and see pickups and redemptions. Shops never message anyone; the app sends the alerts.
