Most modern commercial jewellery continues traditional forms and styles, but designers such as Georg Jensen have widened the concept of wearable art. The advent of new materials, such as plastics, Precious Metal Clay (PMC), and colouring techniques, has led to increased variety in styles.Other advances, such as the development of improved pearl harvesting by people such as Mikimoto Kōkichi and the development of improved quality artificial gemstones such as moissanite (a diamond simulant), has placed jewellery within the economic grasp of a much larger segment of the population.
