muasonit already replaced the diamond. As for the fact that the expert, with a glance at the ring, immediately distinguish muassonit of a diamond is a very bold statement.
Moreover, a serious examination of the stone in the product is fundamentally impossible. All the rest is for movies. For the examination of the stone must emancipate t e removed from their products. This may be due to the infliction of heavy damage to the stone-edge face very sharp and fragile, so easy to cleave and crack. T e he often has cracked, but zakrepke will stand a million years, until it will not remove.
Certification of diamonds - not easy. In Russia, a single stone can not be sold without a certificate, t e examination conducted by the certified organization at them a little. But the product-can! Moreover, the characterization of stone in the product sets himself manufacturer. Therefore, in commercial stores all stones 1 \\ 1 - 3 /4, that is great (they say)!
Abroad, even easier-and a single stone can be sold without a certificate. Although serious organization to sell the X-rays.
A few personal thoughts.
Buying a better single stone, such as Alrosa. There is not deceived, and the stone is a decent certificate, even if the stone is 200 rubles, a certificate with the seal will be (he alone is worth many times more expensive :-) And then insert him into the ring. This service perform many shops and factories, the same crystal.
Difference muassonita and diamonds, rather as between different kinds of natural coffee. But FIAN (or cubic zirconia) - yes, varies dramatically, even in the hand you take and I can hear the difference of weight.
Russian diamonds are always appreciated and continue to be valued on the world market. In U.S. stores stones often Yakut.
In muassonita, there are diamonds grown artificially. Until a carat and clarity, they came naturally, info completely closed for seven locks. Likely to have already reached the commercial.
Associated with this attempt by reason of the ban "blood" diamonds ban entry of stones left, it is unclear where.
Liquidity stones, especially in the product, very low, the floor you are not Picasso. Having bought for 100 rubles, you are unlikely to sell even at 30.
But it did not help, the market collapses and collapses.

Yes, just ...
IMHO, anything that makes nature, beautiful in itself and as beautiful as cobblestone diamond. A diamond is in fact a piece of coal, coal.
Its easy to burn, it burns without residue. So he-a part of nature, its object, not the intellectual product. In the cubic zirconia has its beauty, it has long been an independent jewelry material. Especially beautiful large stones. One drawback-heavy.
Crystal-too amazingly beautiful stone. Previously, he imitated the diamond, and very skillfully. These products are on permanent display in the Hermitage, t e are already works of high art, though well-written rock crystal, imitation diamonds.
