What is striking is that transparency, especially the cabochons, “very good”, “high” or similar called mostly “good”, even if it very obviously is contrary to the inspection. Also notice that the level of trade mostly not specified in the report. Serious reviewers Note: If the specified value represents the wholesale value or the replacement value of the retail trade. -It increasing amounts of precious stones are offered, which are propagating in small plastic boxes common in the gemstone trade packed and sealed mostly via lead seal. So far, no large single stones in this way were offered to my knowledge. -The total value assigned in the opinion of the Stones is mostly between 50,000 and 100,000, in rare cases, but also significantly higher.
In the biggest known to me, but uncovered fraud amounted to “Estimate” on 160 million schillings. COSCO brings even more insight to the discussion. -The average stone weight per box is usually between 50 cts and 100 cts. The cans are filled mostly nationwide. -Only rubies, sapphires and emeralds are offered. So far no case I understand is where such fraud was attempted with other stones. -Usually offered both cabochons and faceted stones. Offerings, which include only cabochons or only faceted stones, are rather the exception. -The average weight of the used cabochons is typically between 0, 50 cts and 2 cts per stone.
In exceptional cases, even stones are up to 5cts. -The average weight of the used faceted stone is much lower and is usually in the range from 0, 20 cts to 1 cts per stone. In exceptional cases, but also smaller (especially round) were and slightly larger stones (up to approx.) 3 cts) offered. -The Ruby cabochons are opaque and dark red to brownish-red color. -The quality of the faceted rubies varies greatly, ranging from poor (mostly brown-tinged) color at medium-good clarity to good color at full opacity. In any case, the goods in the shops is not for sale! -The transparency of Sapphire cabochons is sometimes slightly higher, than that of Ruby cabochons, but is still considered low. The color is always a very dark, almost black blue. Applies that same as for faceted Ruby faceted sapphires. -Emeralds (cabochons and faceted) are often significantly more transparent, sometimes but also opaque (opaque). The color is either very light or very dark. Often, the stones show a variety of black inclusions, which makes it uninteresting for the trade. Whether the providers of such games are the scammers themselves, or whether it involves persons, who themselves were deceived, and now, in good faith and without intention of fraud before langer Time acquired stones want to make money, it is usually not say. But as the, unless we can advise only Center of the Viennese gem, to leave of such offers, the price is also tempting low!
