P\u0159ed lety jsem na tr\u017en\u00edm st\u00e1nku koupil \u0161\u0148\u016frku, o kter\u00e9 jsem si myslel, \u017ee je Akoya. Pozd\u011bji jsem ji nechal ocenit. Sladkovodn\u00ed perly. Vlastn\u011b docela slu\u0161n\u00e9 sladkovodn\u00ed perly \u2014 jen ne to, za co jsem zaplatil. Tato chyba m\u011b nau\u010dila, jak spr\u00e1vn\u011b rozli\u0161it Akoya od sladkovodn\u00edch perel, a up\u0159\u00edmn\u011b to nen\u00ed tak t\u011b\u017ek\u00e9, jakmile v\u00edte, na co se d\u00edvat. Tyto dva typy se neust\u00e1le zam\u011b\u0148uj\u00ed, proto\u017ee mohou vypadat podobn\u011b p\u0159i slab\u00e9m osv\u011btlen\u00ed nebo na \u0161patn\u00fdch online fotografi\u00edch. Ale zbl\u00edzka, vedle sebe, jsou rozd\u00edly skute\u010dn\u00e9 a viditeln\u00e9. Zde je p\u0159esn\u011b to, co je od sebe odli\u0161uje.<\/p>\n

Jsou perly Akoya slanovodn\u00ed nebo sladkovodn\u00ed?<\/h2>\n

Nejprve si to vyjasn\u011bme, proto\u017ee se na to pt\u00e1 spousta lid\u00ed. Perly Akoya jsou slanovodn\u00ed perly. P\u011bstuj\u00ed se v \u00fast\u0159ic\u00edch Pinctada fucata v chladn\u00fdch pob\u0159e\u017en\u00edch vod\u00e1ch Japonska \u2014 p\u0159edev\u0161\u00edm v prefektur\u00e1ch Mie, Ehime a Nagasaki. Sladkovodn\u00ed perly naopak rostou v mu\u0161l\u00edch v sladkovodn\u00edch jezerech a \u0159ek\u00e1ch, p\u0159edev\u0161\u00edm v \u010c\u00edn\u011b. Zdroj vody je jin\u00fd. Ml\u017e je jin\u00fd. Cel\u00e9 podm\u00ednky r\u016fstu jsou zcela odli\u0161n\u00e9. Toto rozli\u0161en\u00ed je ko\u0159enem v\u0161ech ostatn\u00edch rozd\u00edl\u016f mezi nimi.<\/p>\n

\"01.<\/p>\n

Podm\u00ednky slan\u00e9 vody v Japonsku jsou chladn\u011bj\u0161\u00ed a \u00fast\u0159ice rostou pomaleji. Tento pomalej\u0161\u00ed r\u016fst vytv\u00e1\u0159\u00ed pevn\u011bj\u0161\u00ed a hust\u0161\u00ed vrstvy perle\u0165oviny. Sladkovodn\u00ed mu\u0161le rostou rychleji v teplej\u0161\u00ed vod\u011b, co\u017e vytv\u00e1\u0159\u00ed jinou strukturu perle\u0165oviny. Ani jeden typ nen\u00ed \u201efale\u0161n\u00fd\u201c nebo absolutn\u011b hor\u0161\u00ed. Jsou to prost\u011b strukturn\u011b odli\u0161n\u00e9 perly. Kdy\u017e se tedy n\u011bkdo pt\u00e1, zda jsou perly Akoya slanovodn\u00ed nebo sladkovodn\u00ed, odpov\u011b\u010f je jednoduch\u00e1 \u2014 v\u017edy slanovodn\u00ed. Pokud prodejce n\u011bco ozna\u010d\u00ed jako Akoya a nen\u00ed to slan\u00e1 voda, jde o nespr\u00e1vn\u00e9 ozna\u010den\u00ed.<\/p>\n

Jak rozli\u0161it Akoya od sladkovodn\u00edch perel podle lesku<\/h2>\n

Lesk je zdaleka nejv\u00fdrazn\u011bj\u0161\u00edm znakem. Perly Akoya maj\u00ed ostr\u00fd, t\u00e9m\u011b\u0159 kovov\u00fd lesk. Pod\u00edvejte se na jednu pod lampou a uvid\u00edte ostr\u00fd, jasn\u011b definovan\u00fd odraz zdroje sv\u011btla \u2014 t\u00e9m\u011b\u0159 jako byste se d\u00edvali do mal\u00e9ho zrcadla. Sladkovodn\u00ed perly maj\u00ed m\u011bk\u010d\u00ed, v\u00edce rozpt\u00fdlenou z\u00e1\u0159i. Kr\u00e1snou sv\u00fdm zp\u016fsobem, ale znateln\u011b odli\u0161nou. Zdroj sv\u011btla se m\u00edrn\u011b rozmaz\u00e1v\u00e1, m\u00edsto aby se odr\u00e1\u017eel \u010dist\u011b.<\/p>\n

\"02.<\/p>\n

Dr\u017ete oba typy vedle sebe pod stejn\u00fdm sv\u011btlem a rozd\u00edl je z\u0159ejm\u00fd b\u011bhem n\u011bkolika sekund. Akoya vypad\u00e1 jasn\u011b a ost\u0159e. Sladkovodn\u00ed vypad\u00e1 teple a m\u011bkce. Ani jeden nen\u00ed univerz\u00e1ln\u011b lep\u0161\u00ed \u2014 z\u00e1le\u017e\u00ed na tom, jak\u00fd vzhled chcete \u2014, ale tento jedin\u00fd test je nejrychlej\u0161\u00ed zp\u016fsob, jak odli\u0161it perly Akoya od sladkovodn\u00edch perel. Online fotografie tento rozd\u00edl \u010dasto skr\u00fdvaj\u00ed, a pr\u00e1v\u011b proto se tolik kupuj\u00edc\u00edch p\u0159ed n\u00e1kupem zmate.<\/p>\n

Akoya vs sladkovodn\u00ed perly: Rozd\u00edly ve tvaru a velikosti<\/h2>\n

Tvar je druhou velkou indici\u00ed. Perly Akoya jsou t\u00e9m\u011b\u0159 v\u017edy dokonale kulat\u00e9 nebo velmi bl\u00edzko tomu. Proces p\u011bstov\u00e1n\u00ed a biologie \u00fast\u0159ice p\u0159irozen\u011b produkuj\u00ed tento kulat\u00fd tvar velmi konzistentn\u011b. Sladkovodn\u00ed perly p\u0159ich\u00e1zej\u00ed v mnohem \u0161ir\u0161\u00ed \u0161k\u00e1le tvar\u016f \u2014 kulat\u00e9, t\u00e9m\u011b\u0159 kulat\u00e9, ov\u00e1ln\u00e9, knofl\u00edkov\u00e9, kapkovit\u00e9 a barokn\u00ed. Pokud se tedy d\u00edv\u00e1te na \u0161\u0148\u016frku s m\u00edrn\u00fdmi nepravidelnostmi nebo r\u016fzn\u00fdmi tvary, je velmi pravd\u011bpodobn\u00e9, \u017ee jde o sladkovodn\u00ed perly, nikoli o Akoya.<\/p>\n

\"03.<\/p>\n

Velikost se tak\u00e9 li\u0161\u00ed. Perly Akoya se obvykle pohybuj\u00ed od 6 mm do 9 mm, v\u00fdjime\u010dn\u011b dosahuj\u00ed 10 mm u vz\u00e1cn\u00fdch pr\u00e9miov\u00fdch sklizn\u00ed. Sladkovodn\u00ed perly mohou dor\u016fst v\u011bt\u0161\u00edch rozm\u011br\u016f \u2014 n\u011bkdy 10 mm a\u017e 13 mm \u2014, proto\u017ee mu\u0161le m\u016f\u017ee produkovat v\u00edce perel najednou a nem\u00e1 stejn\u00e1 omezen\u00ed. Velk\u00e1, dokonale kulat\u00e1 b\u00edl\u00e1 perla ozna\u010den\u00e1 jako Akoya s 11 mm nebo 12 mm by m\u011bla okam\u017eit\u011b vzbudit podez\u0159en\u00ed. Takov\u00e1 velikost u opravdu kulat\u00fdch Akoya je v\u00fdjime\u010dn\u011b vz\u00e1cn\u00e1 a m\u011bla by m\u00edt i v\u00fdjime\u010dn\u011b vysokou cenu.<\/p>\n

Cena je tak\u00e9 spolehliv\u00fdm ukazatelem<\/h2>\n

Zde je n\u011bco praktick\u00e9ho. Skute\u010dn\u00e9 Akoya perlov\u00e9 n\u00e1hrdeln\u00edky<\/a><\/b> prost\u011b stoj\u00ed v\u00edce na produkci ne\u017e sladkovodn\u00ed.

Pokud vid\u00edte n\u011bco ozna\u010den\u00e9 jako Akoya za 50 dolar\u016f nebo m\u00e9n\u011b za cel\u00fd \u0161\u0148\u016frkov\u00fd n\u00e1hrdeln\u00edk, t\u00e9m\u011b\u0159 jist\u011b to nen\u00ed prav\u00e1 Akoya ze slan\u00e9 vody \u2014 jsou to sladkovodn\u00ed perly, mo\u017en\u00e1 omylem nebo z\u00e1m\u011brn\u011b \u0161patn\u011b ozna\u010den\u00e9.<\/p>\n

Kontrola nacre a v\u00e1hy<\/h2>\n

Perly Akoya maj\u00ed ten\u010d\u00ed jednotliv\u00e9 vrstvy nacre ne\u017e perly South Sea, ale hust\u0161\u00ed celkovou strukturu d\u00edky r\u016fstu v chladn\u00e9 vod\u011b.
