pukhraj ko anya prakritik ratnon se alag karna kuch saral hai lekin pukhraj ko kritrim pukhraj aur vah bhi alg-alag tarikon se bane hue pukhraj se sirf dekhakar alag karna bahut hi kathin hai. inhen yantra se ek-dusre se alag kiya ja sakta hai.
is ank men ham apko pukhraj ke bare men kuch khas baton se avagat karaenge.
pukhraj, jise angreji men yellow sapphire corundum kahte hain dekhne men halke pile ya gahre pile rang ka hota hai. yah chamkila aur paradarshi hota hai. yah safed rang ka bhi hota hai jise angeraji men white sapphire corundum kahte hain.
asli aur nakli pukhraj:
pukhraj ki tarah dekhne vale kai prakritik evan sinthaitik ratn upalabdh hain. sirf ankhane se pahchan karna bahut kathin hai. jaise
prakritik: yellow beryl, natural zircon, natural spiral, tourmaline, scapolite, topaz, citrine quartz, chrysoberyl etc.
kritrim: scz, synthetic spinal, syn glass, synthetic yellow sapphire
synthetic yellow sapphire bhi alg-alag vidhiyon se banta hai. kuch ko to sirf dekhakar pahchanna namumkin sa hi hai. jais
1. flame fusion method
2. flux fusion method
3. cgochralspi method
4. hydrothermal method
5. floating zone method
ise alg-alag ko alg-alag vidhiyon se pahchana jata hai. aie janen ki in sabhi men kaise antar kiya jata hai. vaise to pukhraj ko anya prakritik ratnon se alag karna kuch saral hai lekin pukhraj ko kritrim pukhraj aur vah bhi alg-alag tarikon se bane hue pukhraj se sirf dekhakar alag karna bahut hi kathin hai. inhen yantra se ek-dusre se alag kiya ja sakta hai. ratn prayogshala men istemal hone vale kuch khas yantra ya madhyam nimnalikhit hain.
1. reference: isse ratnon ki prakash ko morne ki kshamata ko ankte hain. har ratn ki apni ek nirdharit sima hoti hai jise tp arthat kahte hain jo alag ratnon ke alg-alag rasaynik sanyojan par adharit hai. pukhraj evan kritrim pukhraj ki ri ek si hi najar ati 1.76-1.77 dr 008 yah ek jaisi islie hoti hai kyonki donon ka rasaynik sanyojan ek jaisa hota hai jo dusre prakritik ratn hain unhen bahut hi sarlta se alag kiya ja sakta hai kyonki yah kabhi bhi 1.76-1.77 dr 008 n hokar kuch aur milegi jaise bpajatapadam fanantajra (sunaila) ki 1.54-1.55 .dr 008
2. apekshik ghanatva: isse ham ratn ka ghanatva napakar dekhte hain ki vah pani se kitna guna bhari hai. isse prakritik ratnon ko, jo dekhne men ek hi rang ke hote hain, alag kiya ja sakta hai. parantu prakritik pukhraj evan kritrim pukhraj men fark nahin kiya ja sakta.
3. pulariscope: kuch ratn singly refractive (sr) tatha kuch doubly refractive (dr) hote hain. dr men bhi uniaxial evan biaxial hote hain. svabhavik banavat ko dekhakar ham yah bata sakte hain ki amuk ratn kaun sa ho sakta hai. pukhraj men dr, uniaxial lete hain. isse ham kafi ratnon ko alag kar sakte hain.
4. dricroscope: isse ham ratnon men pleochroism dekhte hain. sr ratnon men pleochroism nahin milta, dr ratnon men pleochroism dikhai deta hai. ismen bhi 2-3 rang dekh sakte hain. 2 rang ko dichroism aur 3 rang ko trichoism kahte hain. jaise pukhraj men dichroism dikhai deta hai parantu glass men pleochroism hi nahin milta.
5. microscope: yah bahut mahatvapunr yantra hai. isse bhi ham bahut se ratn alag kar sakte hain. pukhraj (prakritik) men aisi bahut si khubiyan hoti hain jinse ap ise dusre ratnon se alag kar sakte hain.
prakritik pukhraj men hexagonal zoning, haxagonal crystals, liquid fingerprints, directional needles, silk adi dikhai de sakte hain.
synthetic yellow sapphire immersionscope men plato lines (fluxo fusion) dikhai dete hain. gas bubbles bhi dikhai de sakte hain.
synthetic yellow sapphire : flux fingerprints, seed plate (flux fusion) flux remnants dikh sakte hain.
in sabhi khubiyon ko dekhakar v pahchan kar ek ratn visheshagya asli v nakli pukhraj ko ek dusre se asani se alag kar sakta hai.
ek vichar: yah dharna jo ratn bilkul kanch ki tarah saf hota hai usmen bal jaise dikhne vala kuch bhi nahin hona chahie bilkul galat hai.
achche se achche pukhraj men bhi koi n koi chote bal jaisa inclusion mil hi jata hai. kanch jitne saf 1,00,000 pukhraj men se 1 ya 2 hi pukhraj nikal pate hain to fir ye to bare nau ratn hain.
