BOULDER OPAL SPLITS AND ROUGH
AT AUSTRALIAN FIELD PRICES
|
See our Queensland Boulder Opal section for finished stones from
our mine at
mine prices.
We have established a relationship with Boulder opal's primo miner from the richest and most
productive mines in Queensland. We discount for volume purchases at prices as low or lower
than
AUSTRALIAN MINE-FIELD PRICES. Quality and Price is determined by the visible cutting
material or as display specimens. BIG DISCOUNT described below.
Boulder opal is a "seam" opal in an ironstone matrix. The dark brown matrix polishes well. The
opal seams are usually sculpted, except for thick bars that are cut traditionally. Our stock does
not include the highest quality gem pieces, they can be obtained by special
request. Generally, purchasing boulder opal from Tibara is like buying it at field prices -- like
buying it at the mine, without buying plane tickets, etc.

ROUGH MATERIAL BY THE POUND
It sells for $6 to $12 per pound. Quantity prices available on request. How much usable opal is
in
it? The truth is that it is unknown how much opal is there. One must use all the normal
indicators. But be realistic -- this is low grade material. Having said that, cutters have lots of
fun
discovering what is "in there!"
