Fire opal:)
most expensive
All else being equal: carat weight, cut, and clarity, a red diamond will always be more expensive than a white diamond.
Black diamonds are more porous and from younger sedimentary rocks, so they are not as expensive as other diamonds.
No. They mean the same thing.
No, chocolate diamonds are usually less expensive than regular -- white -- diamonds, given equal cut, clarity and carat weight.
Yes, some larger stones are worth more than some diamonds sheerly by their size.
Natural gemstones are generally more expensive than created gemstones due to their rarity and unique characteristics. Created gemstones are usually more affordable and have a more consistent quality and availability. However, the value of a gemstone also depends on factors like its size, clarity, color, and cut.
It varies hugely with the type and quality of opal. In general the black opal (lights against a dark background) is more expensive than milky opal (lights against a creamy background). But opals are very individual, and prices depend on the appeal of a particular stone as presented, or a cutter's eye for its potential.
Opal's weight can vary depending on its type and water content, but it generally has a specific gravity of about 1.98 to 2.20. This means that opal is lighter than many other gemstones, such as diamonds or sapphires. The weight of a specific opal piece can be determined by its size and density, with common sizes ranging from a few carats to several hundred carats.
The specific gravity of opal typically ranges from about 1.98 to 2.20, depending on its water content and composition. This variation is due to the presence of silica and water within the opal structure. Opal's unique properties, including its play-of-color, can also influence its specific gravity slightly. Overall, it is generally lower than that of many other gemstones.
the best opal can be more valuable than the best rarest black diamond
I like the pun...if that was your intention. Opal rough (rock before it's cut) tends to be on the softer side than the other precious gemstones (ruby, sapphire, emerald). It has a hardness between 5.5-6.5 on the mohs scale. So opals when constantly worn could become scratched and needs to be repolished time to time
Natural Gemstones prices are always high in comparison to created gemstones. Natural gemstone retain the energy of earth and created gems of laboratory. Astrologically only natural gemstones gives benefits.
Yes, opal is relatively fragile, but not as fragile as many people believe. They are rated 6 on Mohr's hardness scale, and have the same strength as the equivalent piece of glass. they are quite stable, and difficult to crack, but naturally should not be allowed to slam into hard surfaces. They do not crack, and it is a myth that they need to be rubbed with oil to prevent cracking (they are non-porous and do not absorb oil or other liquids).
Fine-quality rubies are some of the most expensive gemstones, with record prices over $1,000,000 per carat. However, rubies are also subjected to more than 1
what is more expensive than the dress
Australian opals are known for their vibrant play-of-color, while Ethiopian opals typically exhibit a more honey-like coloration with flashes of red, orange, and green. Ethiopian opals are also generally more translucent than Australian opals.
