A translucent gem is a type of gemstone that allows light to pass through it, creating a unique and beautiful effect. Two examples of translucent gems are MOONSTONE and OPAL, both of which have been used in jewelry for centuries. MOONSTONE is a milky white gemstone with a shimmery appearance, while OPAL is a multicolored gemstone with a unique play of color. TOPAZ is another translucent gemstone, usually found in shades of yellow, orange, and brown.
