Selling Guide
Where to Sell
Etsy, eBay, or Mercari. These platforms cater to rockhounds and the 'crystal healing' market where aesthetics drive sales.
Selling Tips
Photograph in bright, natural sunlight or under a direct lamp to capture the 'rainbow' flash, as this is the primary selling point. Use keywords like 'Iridescent,' 'Rainbow,' 'Mineral Specimen,' and 'Silicon Carbide.' Package very securely in bubble wrap as the crystals can be brittle.
