False lighting

False lighting is the act of adding a fake spark to spent gems. False lighters act as counterfeiters in the gem craft world. After a gemstone has been used to augment magic ability, the light, or spark, is drained from it. While still worth money, a dark gem's value is only a fraction of what it once was. False lighters are often artificers and even stone casters themselves. They "relight" the spent gems using the sparks from lesser gems or by other, alchemical, means. False lighting is illegal in every city state in Gilthanon,
