Ua loaʻa he 925 gula

No ka gula oka a GOST i kekahi laulā cia - kēia hōʻike, a hiki hooholo i ka helu o nā'āpana poʻohiwi o ka mea maikai i metala na i ka 1000 māhele o ke gula oka a pau. No laila, i loko o ka Russian Hui kauoha aku 925 gula mea,ʻaʻole ma laila. Ma nā Usenet Jewelry pinepine kamaʻilio nui nīnau: "Ua loaʻa he 925 gula?" I kekahi manawa, i kēia nīnau hiki ke loaʻa ka pane: ". UaʻO keʻokeʻo gula" Aia hoʻi, ka mea keʻokeʻo gula oka a mea o ke aliʻi metala me kekahi mea hiki ke hooheheeia keʻokeʻo: manganese, nikala paha palladium.

Mea keʻokeʻo gula ua i ka 1920 a me ka manawa ia ua lilo loa kaila mea no keʻano o ka Jewelry poʻe i hana i kā lākou mau masterpieces mai ia. No laila, i kēia mau huahana e lilo increasingly mahalo i waena o connoisseurs o ke olonā i Jewelry. Kaʻia "keʻokeʻo" hoʻohuʻu he 'ano laulā huahelu o ka malu, mai haikea mea eleele e pale yellow, e hiki i hele mai ma ka a pink haikea. I kekahi manawa, ma ka Jewelry hana, e kiʻi i ka loa keʻokeʻo ili, ka hoʻohana 'ana i ka penaʻana o ka rhodium, i mea kumukuai nui aku ma mua o ke gula. Kēia ka penaʻana i hāʻawi mai i ka huina hoonui me ka huali alohi, maoli i ko lakou paakiki, a mae wale ia'ku, ka pale 'ia mai scratches a me ka poho.

E loaa keʻokeʻo-waihoʻoluʻu gula oka a kila ua pinepine hoʻohana 'ia ma ka hou ia palladium. E like oi loa keʻokeʻo'ōniʻoniʻo ma ka hou platinum oka a pau. Ma ka hapanui o nā kinolau ka hoʻohana nike hou o ka nikala. Eia naʻe, kauka hookupaa i loaʻa i allergic e nikala kekahi kanaka mai o ewalu, no laila, i ka makahiki 2000 i loko o nā'āinaʻEulopa i loko o ka Jewelry i ke keʻokeʻo gula nikala i hoʻohui 'ia kēia. Waiwai o keʻokeʻo gula oka mea okoa ke kaumaha ma muli o ka huliāmahi a me ke ano i hoʻohuiʻia i ka oka a ana o ke hooheheeia, nae, 925 gula i loko o Rusia ua i hoopuka ia, no ka mea a pau i ka Jewelry gula, nānā 'ole o ko lākou mau waihoʻoluʻu a pau, e like me ka mea i hoʻokumu puke maʻamau, hiki wale nō e 375, 583, 585, 750 a me 958 Eia kekahi laʻana.

Mua, ma mua o ka hana mea hou i hana muaʻole o keʻokeʻo kala gula ua pinepine hoʻohana no ka hana o ka daimana Jewelry, like keʻokeʻo Hōʻike 'ka loaʻana o kēia mau gems alohi a me ka hana i mea hou hopena o ke kau. A laila, Ua hoʻouka kekahi na diamonds ma huahana o keʻokeʻo gula e like me ka oka a pau o ke gula, a me ka palladium i IeAUPIIe, IAa IO ea a me ka palupalu, no laila ia mea oi loa maikai e Komo iho i loko o ia gemstones. Eia naʻe,ʻaʻole ia i hoʻohana 'ia 925 ke gula, a me ka loa, he pono ole 750. Kēia ternary oka a pau, mai IeAUPIIe, IAa IO Desha i oi ma mua o ke gula a me ke kālā keleawe ulaula (kekahi manawa kiniki, nikala a me ka palladium), ka mea hiki ia i loko o kekahi mau waihoʻoluʻu - mai ka ulaula i keʻokeʻo.

Kaawale mai ona aku, he kaiāulu e halii mai i ke gula oka 585. I ka haku mele 'ana o ke gula 585 i kekahi nō kāu ekolu-ala, no hoi i kona ano he ākea huahelu o okoa'ōniʻoniʻo, ke kaumaha ma muli o ka noi ligature - mai ka ula i keʻokeʻo. Ke kaumaha ma muli kona haku mele 'ana, ka mea hiki i kekahi paakiki a me kekahi mahele heheʻe i ka mahana, IeAUPIIe, IAa IO ia ka oka a ua loa mākou ke pane pono i kaʻai. Haahaa hāpana 375 nō kāu i ka iki hāmauʻana ulaula waihoʻoluʻu a lilo oho kamaʻilio me ke poho o ka anaiia.

I ka lani kiekie loa hāpana o ke gula - ka oka a pau o ka 958 e ho'āʻo ai, oia no hoi ternary oka a me ka hou ana o ke gula, he kālā a me ke keleawe ulaula. Aie i ka maʻiʻo kiʻekiʻe o ke gula ia mea loa palupalu, a nolaila, hua mai la i Jewelry, mai ka oka a anaiia mālama loa ia. He IeAUPIIe, IAa IO mai he kiʻi pahee melemele kala like 'ole, i mea kokoke i ke ano o ke gula maikai, a uaʻano nui hoʻohana' ia i loko o ka hana o ka mare apo.
