AUSTRALIAN BOULDER OPAL ROUGH CHART
Australian Boulder Opal Rough is mined over thousands of square kilometers in central Queensland Australia. Below is a chart showing many of the amazing types of Rough Boulder Opals that have been found and mined in Australia.
The major Opal fields are Winton, Quilpie, Yowah, Korit, Opalton with many opal mines hundreds of kilometers away from any regional town. So if you meet an opal miner and he invites you to his mine you are best to take provisions for a 2 day drive! Some boulder opal is even mined closed to the Northern territory border. Many Opal cutters will specialize in one particular area as boulder opal is found in veins in bedrock and has to be split or sawn or chipped open to expose opal colors.
Most Boulder Opal is sedimentary so it is not cabochon but some colors and pattern are spectacular and opal splits make ideal earrings.
Lightning Ridge Opal needs water to clean the Rough Opal but Boulder Opal is found in more desert conditions and water is scarce even though the Artesian water trough is close by. To combat the lack of water dry agitators are commonly used to expose Opal veins in the host bed rock and bulldozers work well in these hot dry dusty conditions.
Diesel fuel is expensive now and many Opal miners spend thousands dollars each week on fuel so Opal is getting more expensive to mine and harder to find large deposits of Boulder Opal.

DIAGRAMMA GREZZO OPAL A BASSA DEL BOULDER AUSTRALIANO
L'australiano Boulder Opal Rough viene estratto su migliaia di chilometri quadrati nel Queensland centrale dell'Australia. Di seguito è riportato un grafico che mostra molti dei fantastici tipi di Opali Rough Boulder che sono stati trovati e estratti in Australia.
I principali giacimenti di opale sono Winton, Quilpie, Yowah, Korit, Opalton con molte miniere di opali a centinaia di chilometri da qualsiasi città regionale. Quindi se incontri un opale minatore e ti invita alla sua miniera, è meglio prendere provvedimenti per un viaggio di 2 giorni! Un po 'di opale di boulder è addirittura estratto vicino al confine del territorio settentrionale. Molti tagliatori Opal si specializzano in una particolare area in quanto l' opale boulder si trova nelle vene nel substrato roccioso e deve essere diviso o segato o scheggiato per esporre i colori opali.
La maggior parte di Boulder Opal è sedimentaria quindi non è cabochon, ma alcuni colori e motivi sono spettacolari e le fessure opaline rendono gli orecchini ideali.
Lightning Ridge Opal ha bisogno di acqua per pulire l'opale grezzo, ma l'opale Boulder si trova in condizioni più desertiche e l'acqua scarseggia anche se l'abbeveratoio Artesiano è vicino. Per combattere la mancanza di acqua, gli agitatori secchi sono comunemente usati per esporre le vene opaliche nella roccia del letto di accoglienza e i bulldozer funzionano bene in queste condizioni polverose calde e asciutte.
Il carburante diesel è costoso ora e molti minatori Opal spendono migliaia di dollari a settimana per il carburante, quindi Opal diventa più costoso da estrarre e più difficile da trovare grandi depositi di Boulder Opal.

You are living my dream! I grew up having free reign at the Opal Hill Fire Agate mine not far from palo verde, California. Helen Madden owned it at that time(60's, 70's, and 80's), and let me collect all the Fire Agate I wanted. I took buckets home and buried them in the yard. I dig one up when I run out of the last batch! The fire in it is comparable to L. R. White Opal! My question is this: Can you "call colors" out of fire opal like I can with fire agate?
