Ibukeka kanjani i-tourmaline?

Ucwaningo lwesayensi namakhemikhali seluthuthuke kwaze kwafika ezingeni lapho amaminerali imvelo kuphela engasinika yona ngaphambili atshalwa kalula elebhu. Ngokuvamile, amatshe okwenziwa adluliswa njengemvelo futhi anikezwe ngentengo efanayo. Kodwa izindleko zamakristalu emvelo ngokuvamile ziphakeme izikhathi eziningi kunezokwenziwa, ngakho-ke ukuze ungakhohliswa, kunezici ezithile ze-tourmalines yemvelo.

Okusobala, okukhanyayo

Itshe eliyigugu lemvelo lingaba kokubili obala ngokuphelele futhi likhanye, kodwa ukukhanya kudlula ngokwakho kuzo zombili izimo. Ukucwebezela kwayo kuyingilazi, kukhanya, kepha kwesinye isikhathi indawo engaphezulu ingaba nenhlaka, inamafutha. Uma unquma ukuthenga ubucwebe nge-tourmaline, khona-ke kufanele wazi ukuthi itshe lemvelo linzima kakhulu, kunzima kakhulu ukulibhala futhi ushiye uphawu kulo. Futhi, ku-gem yemvelo, i-shading eguquguqukayo ibonakala ngokucacile futhi into eyingqayizivele ye-polarization yokukhanya okudlula ngokuhambisana ne-optical axis ivezwa ngokucacile.

Imiphi imibala

I-Tourmaline inemithunzi engaphezu kuka-50. Ngokuya ngokungcola kwamakhemikhali, ingapendwa ngemibala ehlukahlukene:

• pink - kusukela kumbala wetiye rose kuya obomvu ocebile;
• eluhlaza - utshani obukhanyayo kuya ku-brown-green;
• eluhlaza okwesibhakabhaka - eluhlaza okwesibhakabhaka kuya eluhlaza okwesibhakabhaka;
• ophuzi - wonke ama-shades of honey, kuze kufike ku-orange;
• black - brown kuya blue-black;
• brown - igolide elikhanyayo kuya ku-brown-honey;
• i-shades eyingqayizivele - i-turquoise ekhanyayo, eluhlaza okwesibhakabhaka enomphumela "we-alexandrite" nabanye abaningi.

I-Polychrome

Okubaluleke kakhulu ku-mineralogy yizinhlobonhlobo ezimangalisayo ze-tourmaline, ezipendwe ngemibala eminingana ngesikhathi esisodwa - amagugu e-polychrome:

• i-watermelon - okusajingijolo okukhanyayo okuphakathi okufakwe umphetho oluhlaza;
• ikhanda le-moor - amakristalu anemibala ekhanyayo ene-top black;
• ikhanda lomuntu waseTurkey amakristalu anombala okhanyayo anethiphu elibomvu.

Ama-nuggets anjalo angokwemvelo angavamile ukufinyelela hhayi kuphela emashalofini esitolo, kodwa ngisho nasezandleni zobucwebe, ngoba ngenxa yokungavamile nokuthandwa kwabo, ezimweni eziningi "zinza" emaqoqweni angasese.
