Goldstone is a glass that was historically made by Monks in Northern Italy. They developed a unique process of glassmaking that incorporated tiny octahedral copper crystals which gave the glass its characteristic sparkle. The contemporary approach is to supersaturate the molten glass with iron, chromium, or copper oxide before carefully cooling to cause these oxides to crystallise, forming plate-like crystals that sparkle.
