Most modern imitation gems are made from glass, ceramic, or which material?

• A. Wood
• B. Diamond
• C. Metal
• D. Plastic

Answer: (D)

Imitation gems today rely on plastics because they’re cheap to produce in large quantities and highly versatile. Clear acrylic and other plastics can be made in many colors, transparencies, and finishes, and they can be faceted or polished to resemble real gemstones while remaining lightweight and durable. This combination of low cost, easy fabrication, and broad visual options makes plastic the most common material for modern fake stones. Wood and metal aren’t used to imitate gemstones in the same way, and diamond is a real gemstone rather than an imitation material. So the material most commonly used for modern imitation gems is plastic.
