Ther is no set answer to this question. Each opal is unique and has its own value. From colorless opal to the most prized fire opal it depends on the size and color. A good place to get the idea of the value of opal is to go to ebay and type in opals. You will see prices from a few dollars to over 50,000 dollars.
Because they are very valuable and are a great trade. Australia mines 98% of the world's opals, and many other countries like to buy them from Australia.
The value of opals varies wildly as the play of color (fire) varies wildly. Opals do not have a fixed value such as gold and silver and the value is open to debate between the buyer and seller. Generally speaking.....if the opals are uncut and of moderate fire - they will not be very valuable.
Coober Pedy is one of the main centres where opals are found in Australia.
The price of opals can vary widely depending on factors such as size, quality, and color. Prices can range from a few dollars for lower quality opals to several thousand dollars for high-quality, rare opals. It's best to research specific types of opals and shop around to find the best price.
The value of pearls and opals can vary significantly based on factors like quality, size, and market demand. Generally, high-quality pearls, especially natural ones, can be quite valuable, often surpassing the price of opals. However, certain opals, particularly those with vivid play-of-color and unique patterns, can also fetch high prices. Ultimately, the value depends on individual pieces rather than the type itself.
The value of opals and amethysts can vary depending on factors such as quality, size, and rarity. In general, high-quality opals can be more valuable than amethysts due to their uniqueness and play-of-color. Ultimately, it's best to have both evaluated by a professional to determine their worth accurately.
Nobody MADE opals. They're mined out of the ground.
Opal stones are relatively abundant in certain regions, particularly in Australia, which produces the majority of the world's opals. Other notable sources include Ethiopia, Mexico, and the United States. While common opals are widespread, precious opals, which display the characteristic play of color, are less common and can be more valuable. Overall, the abundance of opal stones varies significantly depending on the type and quality.
Diamonds come in various colors, including white, yellow, pink, blue, green, and brown. The most valuable diamonds are colorless or near-colorless, often described on a scale from D (colorless) to Z (light yellow or brown). The color of a diamond is influenced by impurities or structural defects in its crystal lattice.
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.
Opals cannot be used as foods. They are hard, precious stones.
