Criteri di valutazione della perla<\/h1>\n

Proprio come il diamante con le sue \u201c5 C\u201d, la qualit\u00e0 di una perla viene valutata secondo 5 criteri detti \u201cle 5 S\u201d.
\nLe 5 S stanno per \u201cShape\u201d (forma), \u201cSize\u201d (dimensione), \u201cShine\u201d (lustro), \u201cSurface\u201d (qualit\u00e0 della superficie), \u201cShade\u201d (colore).
\nTutti questi criteri sono determinanti per stabilire il valore di una perla.<\/p>\n

S come Shape
\n(forma)<\/h2>\n

La perla di Tahiti pu\u00f2 avere 7 forme diverse:<\/p>\n

rotonda<\/strong> (sfera perfetta), a\u00a0bottone<\/strong> (sfera piatta da un lato o allungata nel senso della larghezza), ovale<\/strong> (sfera allungata nel senso della lunghezza), a\u00a0goccia<\/strong> (perla allungata e perfettamente simmetrica, come indicato dal nome), barocca<\/strong> (forma irregolare e non simmetrica), semi barocca<\/strong> (presenta un asse di simmetria e una certa irregolarit\u00e0 all\u2019estremit\u00e0, con cerchiatura o altro), cerchiata<\/strong> (presenta uno o pi\u00f9 cerchi concentrici in rilievo o caratterizzati da una variazione di colore)<\/p>\n

Da notare che le perle rotonde sono le pi\u00f9 ricercate e le pi\u00f9 costose tra le perle di Tahiti.<\/p>\n

S come Size
\n(dimensione)<\/h2>\n

La dimensione di una perla di Tahiti varia generalmente dagli 8 ai 15 mm. Le pi\u00f9 piccole sono comprese tra i 7 e gli 8 mm, ma sono rare. Le pi\u00f9 grandi possono misurare fino a 20 mm. Una perla che supera i 20 mm \u00e8 considerata eccezionale. Ad oggi il record \u00e8 detenuto da una perla di Tahiti della dimensione di 22,5 mm.<\/p>\n

S come Shine
\n(lustro e oriente)<\/h2>\n

Il lustro \u00e8 il riflesso della luce sulla superficie della perla. Si tratta della brillantezza della perla.\u00a0Pu\u00f2 essere ottimo, buono (brillante o molto brillante), tenue o spento (la perla risulta opaca).<\/p>\n

L\u2019oriente \u00e8 il riflesso della luce attraverso i vari strati di nacre chiamati cristalli di aragonite. Pi\u00f9 gli strati sono sottili e numerosi, pi\u00f9 elevato sar\u00e0 l\u2019oriente della perla.
\nPu\u00f2 essere ottimo, buono, discreto o scarso.<\/p>\n

S come Surface
\n(qualit\u00e0 della superficie)<\/h2>\n

Utilizziamo il sistema di valutazione A-B-C-D impiegato dai perlicoltori della Polinesia.<\/p>\n

La combinazione del lustro e dello stato della superficie consente di classificare le perle di Tahiti in 5 categorie.<\/p>\n

S come Shade
\n(sfumatura\/colore)<\/h2>\n

Le perle di coltura di Tahiti vantano la pi\u00f9 ampia palette di colori naturali di tutte le perle del mondo. \u00c8 il loro punto di forza ed \u00e8 ci\u00f2 che le contraddistingue dalle altre. Da questo punto di vista, la Polinesia francese \u00e8 molto severa: contrariamente ad altre perle, il trattamento del colore di una perla di Tahiti \u00e8 proibito. Il colore di una perla dipende da numerosi fattori.<\/p>\n

La maggior parte dei colori presenta un nome generico, non esiste una denominazione ufficiale. I colori pi\u00f9 comuni sono il melanzana, il grigio, il nero, il verde abete, il blu notte, l\u2019azzurro e il rosa. I colori pi\u00f9 rari sono il verde pavone (un mix di sfumature tra cui il blu, il verde, il melanzana e il rosato), il verde pistacchio, il verde tiglio, il bronzo, il cioccolato, il dorato, il giallo e il bianco.
\nTutte queste tonalit\u00e0 possono essere chiare, medie o scure.
\nLe perle di Tahiti presentano spesso una seconda tonalit\u00e0 all\u2019interno della stessa perla.<\/p>\n

Le preferenze in materia di colore variano in base alla zona geografica in cui sono vendute.<\/p>\n
