Evo što su biseri i kako nastaju

U ovom članku objašnjavamo prirodni proces stvaranja bisera. I kako možete znati je li biser pravi ili lažan.

Trebali biste znati da postoje dvije glavne kategorije prirodnih bisera:

prirodni slani biseri koji su vrlo rijetki i definitivno najvrjedniji od svih, jer nastaju prirodno, bez ljudske ruke.

Zapravo, danas je na tržištu vrlo malo prirodnih slanih bisera ( oko 1% ) i slučajno ih otkrivaju lovci na školjke.

i slatkovodni uzgojeni biseri (koji se najčešće koriste u nakitu).

Kako nastaju

Prirodni biseri su organske prirode i rađaju se unutar bisernog mekušca (kamenice) koji, kako bi se obranio od ulaska stranog tijela koje prodire u meko tkivo, aktivira spontani imunološki proces koji prekriva ovo vanjsko tijelo supstancom zvanom "conchiolina". " , koji počinje proizvoditi tanke koncentrične slojeve sedefa, koji dovode do raslojavanja bisera.

Dokazano je da kamenica razvije 3 do 4 sloja ljuske dnevno, pa je zanimljiv podatak da se za svaku godinu uzgoja sloj bisera poveća za 0,3 mm.

Tako ćete se tek nakon nekoliko godina moći diviti izvanrednom rezultatu: prekrasnom prirodnom biseru.

Važno je znati da se među tisućama vrsta kamenica samo nekoliko vrsta smatra pravim bisernim kamenicama.

Elementi vrednovanja bisera

  • Dimenzija
  • Oblik i homogenost
  • Boja
  • Izgled površine
  • Orijentirati

Dimenzija

Veličina je prvi element na temelju kojeg se procjenjuje biser, "upamtite" da su ostali čimbenici jednaki, što je biser veći to je njegova vrijednost veća.

Mjerna jedinica za bisere je milimetar (mm), a njegov promjer moguće je jednostavno izmjeriti tisućinskim pomcem.

Oblik

Ispod su sve postojeće veličine bisera:

  • Kuglasti
  • ovalan
  • Pola bisera
  • Ovaloidni
  • Dugme
  • U obliku kapi
  • Kruškasti oblik
  • Prstenovana
  • Pobratimljeni
  • Zakucan
  • Zrno riže
  • Križ
  • Fantazija
  • Barokni
  • Polubarok

Boja

Biseri dolaze s beskonačnim kombinacijama boja i nijansi, pa je stoga nemoguće stvoriti prave kategorije.

Dolje je navedeno šest osnovnih glavnih boja: bijela , ružičasta , krem , žuta, siva i crna.

Sivi i crni biseri obično se nalaze u područjima gdje je pijesak taman. A proizvodi ih vrsta velike biserne kamenice nazvane "crno usne" iz obitelji "margaritiferous" .

Dok su najčešće nijanse u rasponu od ružičaste do ružičasto-zelene.

Izgled površine

Biseri, iako su uvijek "organski materijal" i stoga prirodni, nikada nemaju savršeno glatku i homogenu površinu.

Stoga, promatrajući biser pod izravnim svjetlom sigurno ćete primijetiti pruge ili male reljefne mjehuriće, to su ohrabrujući elementi koji jačaju hipotezu da je biser pravi i stoga autentičan.

NAPOMENA: Što je savršenija površina bisera, to će biser biti vredniji.

Pearl Orient

Orijentacija bisera je skup optičkih elemenata (disperzija, lom, refleksija, interferencija i difuzija svjetlosti) koji se uočavaju korištenjem difuzne bijele svjetlosti pri promatranju bisera na jednoličnoj bijeloj ili sivoj pozadini.

Ako pri promatranju bisera uočite skup "pokretnih" boja, promatrate orijentaciju bisera. Da je samo stručni tehničar sposoban to procijeniti u:

Izvrsno – Dobro – Dovoljno – Loše

Kako prepoznati lažni biser

Ovom vrlo jednostavnom metodom moći ćete brzo prepoznati je li biser autentičan ili lažan .

Test se sastoji od grebanja površine bisera malom turpijom ili oštricom malog noža (ako ima rupu, bolje je blizu rupe, tako da nakon umetanja u ogrlicu ne vidite ogrebotine) odmah razumjeti ako je premazano bojom ili sličnim proizvodima.

Ako je to slučaj, odmah ćete primijetiti pucanje boje i ispod bilo kojeg poklopca, lažni biser (obično u prozirnoj plastici).

Tako ćete odmah moći razumjeti radi li se o autentičnom ili lažnom biseru. Jer ako je biser prirodan, kada ga zagrebete, primijetit ćete da će se površina bisera oljuštiti (efekt je identičan kao kada zagrebete kost sipe).

    I never thought winning the lottery could be this easy. Last year, I was overwhelmed with urgent bills and had no support. Out of desperation, I decided to search online for tips on how to win the lottery. During my search, I came across several people talking about winning lottery numbers provided by Dr. OGBO. Out of curiosity and hope, I decided to reach out to him. He was kind and offered to help me win the Mega Millions jackpot.He performed a lottery spell for me, and after 15 hours, he sent me some numbers to play. To my greatest surprise, when the results came out, I was among the winners—I won $143 million! Thank you, Dr. OGBO. My life has been completely transformed, and my financial situation has changed for good. This is the best thing that has ever happened to me. If you are looking for help on how to win the lottery, you can reach out to him. Have faith and give him a chance your life could change too.

    I saw Liah's comment about DR Ahonsie’s medication concerning Herpes. I tried it and it worked perfectly. It was like hell living with Herpes all this years until now, no more pains, weakness, and no more buying of anti-viral drug everyday to slow down the viral load. I would've come to testify before now but I have to wait for a couple of months to see if it will come back or feel pain as usual, I also went to the hospital for test and i was tested negative. All thanks to Dr. Ahonsie and to you Liah for spreading the good news. Doctor's contact: .Email: drahonsie00@gmail.com or whatsapp +2348039482367

    Herpes is one of the most common sexually transmitted diseases (STDs), prompting many to wonder how to get rid of herpes naturally. The herpes virus can live dormant inside a person’s immune system for a lifetime, periodically causing blisters that burst and turn into open cold sores or ulcers before healing. When left alone, herpes cold sores usually last about 10-14 days and are uncomfortable for a variety of reasons causing redness, pain, burning and often embarrassment. I was a victim of this Awful Herpes Simplex Virus until I came across https://herbalistrazorherb.wixsite.com/drrazorherbalhome and I am thankful to Herbalist Razor For The Good and miraculous work he did for me. Few weeks after I got his products , I only took his medicine For 18 days and my PCD who had diagnosed me with the virus was astonished when she found no Trace of the virus ever being in my body and declared me Negative, I shed tears of Joy when I received the news from Her .
