Opals are considered rare primarily due to their unique formation process, which requires specific geological conditions, including the presence of silica-rich water and a stable environment over millions of years. Additionally, significant deposits are found in only a few locations worldwide, with Australia being the most notable source. The intricate patterns and colors within each opal also contribute to their rarity, as no two opals are identical. This combination of factors makes high-quality opals particularly sought after and valuable in the gemstone market.
