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.
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.
the best opal can be more valuable than the best rarest black diamond
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
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).
what is more expensive than the dress
Because of a diamonds clarity and its molecular make-up, which is more dense than other gemstones. This is true even when a diamond and a different gemstone are cut exactly the same way.
As funny as it sounds, though synthetic gemstones are much more affordable than their natural counterparts, they are actually the gems that possess the more flawless appearance. Synthetic gemstones are made in laboratories while natural gemstones might appear a bit worn and less brilliant in comparison, due to their exposure to various natural conditions. In addition, most often, synthetic gemstones are more dense than natural gemstones, meaning that natural gems are lighter. There's a great article on Diamond Price Guide about just this topic. Check it out if you want to read more about the differences between synthetic and natural gemstones.
you should first weigh the piece of jewelery to see i it is heavy. if it is not heavy, then it is probably pure and is expensive. some jewelery is heavy and therefore must be compared with the weight of the actual object is was made from.Another Answer'Expensive' is relative.Metal in jewelery can be expensive, especially if a high-karat purity gold is used, or if the metal is platinum. Real, natural gemstones are also more expensive than imitations, even irradiated 'gemstones'. Craftsmanship can be an other indicator, especially where hand-tooling or hand-fabrication are employed.
Opal is a stone that is a clearish whitish background, with different colors scattered around on it. There are colors such as red, orange, blue, green, ect. These colors appear more than once on the stone.
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
Platinum is not more expensive than a beautiful, natural diamond.
