A SIMPLE EXPLANATION

Opal is formed from a solution of silicon dioxide and water. As water runs down through the earth, it picks up silica from sandstone, and carries this silica-rich solution into cracks and voids , caused by natural faults or decomposing fossils. As the water evaporates, it leaves behind a silica deposit. This cycle repeats over very long periods of time, and eventually opal is formed.

Visualise the inside of an opal, like a bag of marbles. The marbles are the silica spheres.

Smaller spheres are more commonly forming, and tend to defract the purple/ blue/ green colours.

Larger spheres are rarer forming, and tend to show off the yellow/ orange/ pink and red colours. Hence why these are the rarer colours to find in Australian Opal.

opel silicon dioxide or pani ke samaadhaan se banataa he.jaise hi pani prithvi ke madhyam se neeche chalaa jaataa he, yah sandstone se silica uthaata he, or is silica-samrudh samaadhaan ko daraaren or voids main le jaataa he, jo prakritik dosha yaa vighatit jeevashmon ke kaaran hota he.jaise hi pani vashpit ho jaataa he, yah ek silica jamaa ke peeche chhod detaa he.yah chakra bahut lambey samay tak doharaata he, or antat opel banataa he.

ek opel ke andar kii kalpana karen, marbles ke ek bag kii tarah.marbles silica gole hai.

chote gole adhik saamanytah banate hai, or bangnee/ nile/ hare rangon ko difract karte hai.

bade gole durlabh hai, or pile/ naarangi/ gulabi or laal rangon ko dikhaate hai.isliye ye australian opel main khojane ke liye durlabh rang kyon hai.

opel ek vishesh ratna he jo ek anokhe tareeke se banataa he.kalpana kiijie ki opel prithvi ke andar marbles ke ek bag kii tarah he.ye marbles silica naamak ek chamakdaar saamagree se bane hote hai.silica ek vishesh prakaar kii ret he.

jab barish hoti he, to pani jameen main bhigo jaataa he or ret se kuch silica ikattha karata he.phir, pani prithvi kii chattaanon main choti daraaron or chhedon ke madhyam se yatra karata he.ye daraaren chattaanon main jeevashmon yaa prakritik brake jaisi chizon dwaara banaai ja sakati hai.

jaisaa ki silica ke saath pani in daraaron ke madhyam se chalata he, kuch jaadui hota he.pani vashpit hone lagata he, jiskaa arth he ki yah ek gas main badal jaataa he or gaayab ho jaataa he.lekin jab pani chalaa jaataa he, to vah silica ke peeche chhod detaa he.bahut lambey samay se, ye silica jamaa kaa nirmaan or sundar opel banaate hai.

opel ke andar silica gole kaa aakaar vah he jo ise apane rang detaa he.chote gole bangnee, nile or hare jaise rang banaate hai.opel main ye rang adhik aam hai.lekin bade gole durlabh hote hai or pile, naarangi, gulabi or laal jaise rang banaate hai.isliye aap un rangon ko opel main aksar nahin dekhte hai.
