What is the size of the gemstone opal?

The size of an opal gemstone can vary widely, ranging from small chips and beads of a few millimeters to larger cabochons and rough stones that can weigh several carats or more. Commonly, opals used in jewelry are typically between 1 to 10 carats, but larger specimens can be much bigger. The size often depends on the intended use, with smaller stones suited for intricate designs and larger ones valued for their rarity and beauty.
