Roberto Coin in war about black jade





Legal controversy in New York between Roberto Coin and an American dealer, Joseph Goldstein on the black jade ♦ ︎

The story is rather singular. On one side a large and esteemed Italian brand, Roberto Coin. On the other, an importer of jade, Joseph Goldstein. Black jade, to be precise. At the center, called to make a judgment, the New York District Court. The diatribe is born on the lawfulness of the use of stone. Or, better, on the definition of black jade. According to Roberto Coin (but the company does not issue statements), the one used for some jewels of the Venetian Maison is a full black jade and the company’s behavior is fully correct, as confirmed by the description of the jewels in the sales information. According to Goldstein, however, only the stone certified by a Chinese body, Ngtc, can really be considered the pure mineral, the one with official license.
In support of his thesis, the importer of the stone, which defines a “solid alternative to black diamonds”, sent a full indictment to the New York judges.

But the reality is that it is only a defensive move, given that the first to take legal action against the American dealer were the lawyers of Roberto Coin.

Will the magistrates of the District Court be able to grasp the crux of the problem? Will they, with the help of expert gemologists, judge the lawfulness of using the black gem? The stone of discord is not a trivial matter, given that Goldstein’s campaign against Roberto Coin risks causing image damage (and economic damage) to the Italian brand, highly quoted on the US market. And, you know, words are as heavy as stones.

The Petals by Roberto Coin





Three jewels for a mini collection by Roberto Coin: flowers ready to show their petals ♦ ︎

Petals that protrude from a flower, but also bridges that connect two souls. In this romantic perspective fits the Petals mini collection by Roberto Coin. They are just three pieces, with an essential design that is often used by the Vicenza jeweler, but softened by a sentimental inspiration in which the flower becomes, when the petals are counted, a sort of love roulette. Only the last petal will know if the desired love is also matched.
The Petals collection by Roberto Coin consists simply of a ring and two pairs of earrings. The bouquet of colored corollas is made of malachite, jade and turquoise. Diamonds and gold recall the image of the petals wet by rain, portrayed just when the sun shines again. More romantic than that … Lavinia Andorno

Black jade climbing

The black jade, charming stone that wants to ascend on the diamonds throne.
Roberto Coin has chosen it for his collection Black Jade: this stone could have a wide diffusion, assuming that if you find a sufficient quantity. To propose this valuable material is now Kings Stone US, a New York company that owns the rights of import to the US. To guarantee the quality and the characteristics of this stone are the National Gemstone Testing Center (NGTC), Chinese institution with the official license, and two American organizations, the American Gemological Laboratories (Agl) and the International Gemological Institute (IGI). The black jade which is proposed, however, does not come from China, but from a mine in South Africa of owned by King Stone, even though the certification of authenticity is the prerogative of NGTC, the leading authority on the subject.
The characteristics presented for this stone (it is jadeite, not nephritis) are relevant: is shining like a diamond and has a hardness of 7.5 to 8.5 on the Mohs scale, more or less so as an emerald or topaz (the Diamond is 10 ranked). In addition, according to King Stone, jade is an alternative to the “blacks treated diamonds”, since it is a stone from the natural color, glossy, and consistent as a precious stone. The effect is fascinating, as evidenced by the collection of Roberto Coin.
