The value of a 2.5 carat opal can vary significantly depending on factors such as the quality, color, clarity, and origin of the stone. In general, opals can range in price from a few dollars per carat for lower-quality stones to several hundred dollars per carat for high-quality stones. It is recommended to have the opal appraised by a professional to determine its exact value.
The cost of a 1-carat opal can vary widely depending on factors such as the type of opal, its quality, and color. On average, prices can range from $30 to several hundred dollars per carat for common opals, while high-quality precious opals, particularly those with vibrant color play, can cost anywhere from $200 to over $1,000 per carat. Additionally, unique opals with rare characteristics can command even higher prices. Always consider purchasing from reputable sources to ensure quality.

If someone was trying to obtain an Opal ring that was made with 14 carat gold they could purchase one at a jewelry store. Opal rings can also be purchased online through a variety of online stores.
The value of a 30-carat opal can vary significantly based on factors such as its type (e.g., black opal, white opal), quality (clarity, color play, and pattern), and market demand. Generally, prices can range from a few hundred to several thousand dollars per carat. Thus, a 30-carat opal could be worth anywhere from $3,000 to over $30,000, depending on these factors. For an accurate appraisal, it's best to consult a gemologist or a reputable jeweler.
A common misconception. Carat is nothing to do with size. Carat is related to weight and therefore a 1 carat stone depends on the gemstone in question and its cut. 1 carat is 0.2g and a 1 carat round-cut diamond is approximately 6.5mm in diameter. Similarly, since CZ is a diamond simulant, a 1 carat round-cut CZ is also deemed to be one that is 6.5mm in diameter but such a stone actually weighs more than 0.2g because CZ is more dense than diamond.
That depends on the cut, carat, color and clarity. For e.g, a round 1 carat D color, IF clarity, and an excellent cut diamond costs about $11, 081 and a 1 carat marquise diamond with the same characteristics costs about $17, 066, both of which are GIA certified.
The value of raw opal can vary significantly based on factors such as quality, color, and size. Generally, raw opal can range from a few dollars per carat for lower-quality stones to over $100 per carat for high-quality specimens. Unique characteristics, such as play-of-color and clarity, can further influence its market price. Collectors and gem enthusiasts often seek out specific types of opal, which can also affect its value.
Three carat diamonds weigh three carats: that's how 'big' they are.
The average number of carats in an opal can vary significantly based on the type and quality of the stone. However, most opals sold in the market typically range from 1 to 10 carats. Larger opals, over 20 carats, are less common and can be quite valuable. The size and carat weight can greatly influence an opal's price and desirability.
A 1.00 point diamond is one carat, so a .12 point diamond is a little over 1/10th of a carat.
If the opal has fire, play of color, it is used for jewelry. Very little gem quality opal is imported by the USA. Most of it goes to Asia.
