NGL IDENTIFICA, CLASSIFICA e VALUTA : Diamanti, Gemme di Colore, Perle , Coralli ,Opali e qualsiasi altra pietra preziosa, discriminandole da Sintesi o imitazioni e ne identifica eventuali trattamenti migliorativi.
NGL works on both loose stones and mounted jewelry and stones.
NGL also carries out its own analyses on the set stones in an absolutely non-invasive way, in the total safety of not damaging the jewel's structure.
NGL chiarisce che potrebbero esserci delle montature che rendono l’analisi difficoltosa ,in casi del genere ,se dovesse essere riscontrata l’impossibilità di valutare con certezza peso e/o colore della pietra, non potrebbe essere rilasciata certificazione ma verrebbe comunque effettuata una stima del valore della gemma e/o dell’oggetto stesso.
NGL upon request the laboratory will issue a signed certificate containing all the data of the jewel or precious stone examined.
The certificate can be on paper or on a plastic card.
Upon request, NGL may add to the paper certificate, in addition to the photo of the jewel or precious stone examined, a further photo of a specific inclusion contained in the stone itself with relative description.
This photo will represent, for the gem itself, a sort of DNA and will allow it to be recognized with a certain certainty, taking advantage of the uniqueness of the inclusion itself.
For specific cases and upon request, NGL has a home delivery service.
Upon request, NGL carries out the hot vacuum oiling of the emeralds
NGL does not issue certificates for stones of synthetic origin
(NGL per quanto attiene le gemme sciolte ,rilascia certificati per i diamanti non inferiori a 0,11 ct. e per quanto riguarda le gemme di colore non inferiori a 0,16 ct.)
