Quick Summary
In mineralogy, resinous lustre describes a mineral's surface appearance, resembling that of yellow resin. This is one of several types of nonmetallic lustre, which are distinguished from metallic lustre by their ability to transmit light. Other nonmetallic lustres include vitreous (like glass), pearly (like mother-of-pearl), greasy (like oiled surfaces), silky (like silk), and adamantine (like diamond). Lustre is determined by a mineral's refractive power, transparency, and structure.12
