RapNet launched a new site on Tuesday, promising a safer, simpler and smarter way of trading diamonds online.

The aspects of RapNet that users enjoy will stay, but the redesigned platform will be easier to navigate, getting those users to their desired diamonds with fewer clicks. There are also handy tools such as a price calculator, the ability to compare up to 10 diamonds at once, and on-screen filtering of search results.

The new site is built on technology that will make it easier to add more features should RapNet choose to introduce them — such as improvements to money-transfer methods and supply-chain traceability.

Crucially, it will be harder to defraud users, explained RapNet chief operating officer Saville Stern (pictured). Traders will be able to communicate using an on-site messaging service, rather than having to exchange emails — an increasingly common target for fraudsters trying to fool people with fake correspondence.

“It’s a safer and easier way to find things, and it looks nicer,” said Stern. “It’s the same RapNet you know, but an easier platform to use, more secure, and built for what’s next.”

Users’ RapNet inboxes will also be simpler for them to search, and will be centralized — meaning traders won’t have to juggle several communication methods, such as email, Skype and WhatsApp. Additionally, the platform will organize messages into threads, conveniently grouping parts of the same conversation together.

RAPAPORT ... Vedúce skupiny v sektore diamantov a klenotov spolupracovali na uverejnení univerzálneho štandardu, ktorý sa má používať pri odvolávaní sa na prírodné diamanty a syntetiká.

Diamantová terminológia je odkaz na diamantový slovník pre všetky odvetvové organizácie, obchodníkov a maloobchodníkov, ktoré používajú, uviedlo v spoločnom vyhlásení deväť priemyselných orgánov v utorok.


V dokumente sa uvádza, že slová "diamant" a "drahokam" znamenajú prírodný pôvod. Priemysel by mal používať "syntetické", "laboratórne " alebo "laboratórne vytvorené" a mali by sa vyhnúť pojmom , "skutočný" a "autentický" pri opise týchto umelých výrobkov.

"Ochrana dôvery spotrebiteľov má prvoradý význam pre dlhodobý úspech nášho priemyslu," uviedla prezidentka (CIBJO) Gaetano Cavalieri. "Smernica o diamantovej terminológii je dôležitým nástrojom na dosiahnutie tohto cieľa tým, že pomáha štandardizovať terminológiu používanú na jasné rozlíšenie diamantov a syntetických diamantov vo všetkých komunikáciách medzi sebou a našimi zákazníkmi."

Smernice sú založené na norme ISO 18323 pre šperky a diamantovú modrú knihu spoločnosti CIBJO, ktoré sú medzinárodne uznávanými odborníkmi v tejto oblasti.

Strany, ktoré vytvorili dokument, okrem CIBJO sú: Svetové diamantové centrum Antverpy (AWDC), Združenie výrobcov diamantov (DPA), Rada pre podporu vývozu drahokamov (GJEP), Izraelský priemysel (IDI) a (IDMA), US Jewelery Council (USJC), World Diamond Council (WDC) a Svetová federácia diamantových burz (WFBD).

Zrejme je a začína to byť problém . Kupujúci má právo vedieť čo kupuje , hoci cenove to nie je obrovský rozdiel...

Práve som čítal, že práve cenový rozdiel je obrovský. Cena syntetického diamantu = 30% ceny prírodného. Preto sa pre syntetické diamanty vyrábajú falošné certifikáty o pôvode ako napr. GIA. Rozlíšiť sa to dá len prístrojovo, preto by to napríklad pre mňa nehralo žiadnu úlohu. Uhlie ako uhlie :)

Rozlíšiť syntetický diamant od prírodného je v domácich podmienkách nemožné.

Rozdiel je v ukladaní prímesí do kryštalickej štruktúry diamantu (dusík) a niektoré syntetické diamanty sú magnetické...

Narazil som na staršiu, ale zaujímavú správu...

HRD Investigates Possible Inappropriate Conduct

RAPAPORT... Sources from the Hoge Raad voor Diamant (HRD) confirmed that four gemologists were asked to resign this week and that an internal investigation is currently being carried out. An official statement released today stated that the graders left ''due to elements that have triggered an immediate internal, ongoing investigation concerning possible inappropriate conduct.''

Rumors have been swirling in Antwerp that the four in question were actively involved in bribery concerning the valuation of an undisclosed number of diamonds. Reportedly, five diamond firms could have been directly involved in the issue.

Georges Brys, the director of HRD Antwerp Lab, explained to Rapaport News, ''Contrarily to what may have been said in the press, the police aren’t at all part of our internal investigation, they aren’t involved yet at this stage. Obviously we questioned our legal department, but we must assess the situation, and then inform our board and the ISO committee. It’s only after those actions, that we’ll be able to take all necessary measures. We can‘t just fire people without informing the unions and giving them a sound motive.''

Brys concluded, ''I must insist that so far, all we have against our former graders is that they made a professional mistake. We have nothing to hide, and we’re not trying to hide anything. All we’re doing is making sure we know the circumstances and the facts.''

Nie je syntetika ako syntetika , hodne záleží na technologickom postupe .
Pre určitú potrebu kvalitných a veľkých drahokamov v priemysle najvačší prispievatelia na výskum a vývoj umelých drahokamov sú vládne organizácie cez rôzne nadácie ...
