Com este artigo queremos lhe dar conselhos úteis para aprender a reconhecer joias falsas.

1. Antes de tudo você precisa saber o peso em quilates ou finura das joias, então a primeira coisa a verificar é o peso em quilates e a marca gravada na joia.

Estes devem estar presentes por lei.

Portanto, se não houver marca ou iniciais gravadas nela, seria uma pista muito relevante, pois a joia certamente poderia ser falsa .

Abaixo estão todos os quilates reais existentes:

8 quilates = 333 milésimos de grama = título 333

9 quilates = 375 milésimos de grama = título 375

12 quilates = 500 milésimos de grama = título 500

14 quilates = 585 milésimos de grama = título 585

18 quilates = 750 milésimos de grama = título 750

22 quilates = 916 milésimos de grama = título 916

24 quilates = 999 milésimos de grama = título 999

Se você examinar a joia com uma lupa, notará os números ao lado do título e do logotipo, estes são os identificadores do fabricante atribuídos pelo órgão competente (região e província do fabricante).

IMPORTANTE!
Se você leu a escrita 750 mas ela não está dentro do símbolo indicado na foto abaixo (losango), então sua joia não é autêntica, mas certamente é falsa.

Marcação de metais preciosos

2. O segundo teste é garantir que as joias não estejam desbotadas ou descoloridas. Lembre-se, as joias de ouro têm uma cor intensa e brilhante por toda parte, então esfregue uma parte da joia com uma pequena lima ou lixa, removendo também um pouco de material, para ter certeza de que não há outros metais por baixo.

3. Outro teste que recomendamos é segurar a joia perto de um ímã para garantir que não haja elementos de ferro ou aço (excluindo o fecho que contém a mola de aço) sob qualquer revestimento.

4. O quarto e último teste que lhe dá certeza absoluta é comprar uma pedra de toque e um pequeno frasco de ácido específico para testar ouro ou prata, existem para todos os quilates existentes.

Você esfrega a joia na pedra e depois coloca o ácido no traço superficial, se este desaparecer significa que a joia não é do material indicado no frasco, pelo contrário se o traço permanecer a joia é autêntica.

Se precisar comprar uma joia de ouro, conte com os Especialistas!

    I GOT RID OF HERPES WITHIN 2 WEEKSrnAm from the north Carolina. I caught genital herpes from my ex boyfriend who never had any symptoms of herpes . I had it for 4 years and it has literally affected my life before I got cured. People think herpes is really a minor skin irritation, herpes has long term effects on health. The stigma attached to this virus by ignorant people is ridiculous. Most people have herpes in one form or another but they might not be aware of it. I would like to advise people on how I got rid of my herpes by using Dr Sikies medicine. I saw a comment posted by a woman from Ireland on the internet that she got rid of her herpes with the help of Doctor Sikies and I was so happy when I saw that post. I quickly contacted doctor sikies regarding a cure for herpes. I explained things to him and he assured me not to worry that he will cure me. I ordered his medicine which was sent to me via DHL. i got the herbal medicine and i used it as i was told for the period of 2 weeks which is twice a day ( morning and at night before going to bed) .after 2 weeks, i found out that the herpes was no more and this was also confirmed by my doctor. If you have herpes or other similar disease and you want it cure, kindly contact Doctor sikies WhatsApp +2348163430143 / Email drsikies@gmail.com Dr Sikies can also cure HIV, stroke, ulcer, depression, autism, cancer, diabetes etc.rnFacebook page https://facebook.com/drsikiesrnPlace your order on this website click: :https://drsikiesherbalcuremedicine.weebly.com/

    A married woman actually planned to ruin my marriage and take my husband away from me and my kids. The whole saga began when my husband started acting weird and staying out late and sometimes doesn’t return back home. I did my findings and found out that an old friend of his who is married was doing everything to break us. I did my best to end their closure but it wasn’t working. Dr Isikolo helped someone I knew and I got to know about him from my friend whom  he helped. When I contacted him, he told me all I needed to know and all that was to be done to separate them.  I complied and he fixed the problem and my husband is focused on me and my kids now and promised forever never to let anyone come in between us. Just as I hoped for better results from Dr Isikolo and he delivered, he can help you too if you reach out to him for any kind of help.

    After being in relationship with him for seven years, he broke up with me, I did everything possible to bring him back but all was in vain. I wanted him back so much because of the love I have for him and I begged him with everything, I made promises but he refused. I contacted a spell caster called DR ISIKOLO that could help me cast a spell to bring him back but I am the type that never believed in spell, I had no choice than to try it, I mailed the spell caster, and he told me there was no problem that everything will be okay before two days, that my ex will return to me before three days, he cast the spell and surprisingly in the second day, it was around 4pm. My ex called me and we resolved the differences and we are happy together now. Anybody could need the help of the spell caster and you can review his website (https://isikolo-temple.com) or call/text him via WhatsApp on: +2348133261196.
