At the time I found myself carrying a small polished stone in my pocket because I found the weight and feel of it so soothing in my hand. It reminded me of my grandfather and how he used to tumble stones and fill empty pickle jars full of beautiful Tiger’s Eye, Agate, and Rose Quartz. I picture the shapes in these paintings as tumbling stones, with the beautiful colors and soothing weight of the stones from my childhood.\"\nShop the Duo- Quartz II","images":["https://cdn.shopify.com/s/files/1/1806/8745/files/Quartz-I.jpg?v=1697493832","https://cdn.shopify.com/s/files/1/1806/8745/files/Quartz-I-_-II_67e20ca5-a010-47dd-9fb7-96c857d1b441.jpg?v=1699389654"],"price":29,"currency":"USD","in_stock":true,"inventory_qty":229977,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:11.811Z"},"share_url":"https://firestarter.network/l/lst_byKz9tCJ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
