They sold. Every jewellery house wanted them, the deposit was worked hard, and the technique spread to everything else on the shelf. The rainbow coatings you now see on quartz points started here, on geodes smaller than a grape.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThat history is why the treatment line on this listing matters more than usual.
