Renowned for their high quality, these mines yield fire agates exhibiting a diverse range of rainbow colors, including reds, greens, purples, and blues.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"Textbody\"\u003e\u003cspan style=\"font-family: 'Arial',sans-serif;\"\u003eThe photographs shown highlight the stone’s color and formation under both artificial full spectrum indoor lighting and natural sunlight to best display its internal fire layers. The vibrant colors within fire agates arise from the Schiller effect, like what is seen in mother-of-pearl and opals. This phenomenon results from alternating layers of silica and iron oxide that diffract light, creating the interference patterns known as fire. Optimal lighting enhances this color play while in dimmer conditions the colors will be less vivid and the stone will appear darker with a brownish hue.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"Textbody\" style=\"margin-bottom: 0in;\"\u003e\u003cspan style=\"font-family: 'Arial',sans-serif;\"\u003ePhotographs Copyright © 2026 Fire Agate US.
