Iris Calloway's first crystal purchase was a "rare blue quartz" that turned out to be dyed agate. She kept it on her shelf anyway—not as a mistake, but as a reminder. The experience taught her that the crystal world is full of confident claims, loose language, and listings that sound scientific without being accurate.
Over nine years of collecting, cataloguing, and studying minerals, Iris has learned that identification is rarely a single moment of recognition. It is a process of elimination: hardness, streak, luster, cleavage, crystal habit, and context. With a certified earth science educator background and a habit of questioning confident labels, she writes guides that walk readers through that process instead of handing them an answer they cannot verify.
Her work covers crystal and mineral identification, formation and crystal systems, common lookalikes, buying basics, ethical sourcing, care and storage, and display ideas. She is particularly interested in the gap between what crystal sellers claim and what mineralogy can actually confirm—and in helping readers appreciate stones for what they are, not just what they are said to do.
When she is not writing or examining specimens, Iris can usually be found at a kitchen table with a loupe, a streak plate, and a labeled box of rocks that keeps getting reorganized.
