Photographing opals: We endeavour at all times to take the most true to life pictures possible. However, cameras often pick up colours and light differently and variations may occur. Because every opal photographs differently, I also include in the description additional comments about the accuracy of the photos.

Lightning Ridge Opal: Mined in the Outback of New South Wales Australia Black Opal comes from and variety of mining areas around Lightning Ridge  

Black Opal refers to the underlying colour – the colour of the opal when you turn it over. The darker the body the more valuable to stone may be. It is this darkness that lends brightness to the other colours displayed with in the stone. Black and dark opal is the scarcest of all opal and comes from the mines of Lightning Ridge.

Queensland Boulder Opal: Mined in the Outback of Queensland Australia our Opal comes from and variety of mining districts including - Winton, Koroit, Yowah, Eromanga, Jundah and Quilpie

Boulder opal is a type of opal that forms within the cavities of ironstone boulders dating from the time when central Queensland was cover by an inland sea The Opal is found in both vertical and horizontal cracks or seams. It is cut with the ironstone remaining on the back and is classified as solid opal.

Boulder Opal occurs over a Vast area of Western Queensland from North of Winton to south of Quilpie. Boulder Opal is considered to be one of the most versatile opals because it has all of the colour and patterns of expensive black or crystals opals but it is contained within the iron stone which makes it extremely durable.

When looked at from the side you can always tell a genuine solid boulder opal by the natural uneven line where the opal filled the void in the boulder.

 

White Opal: is also known as milky Opal and it has a pale white appearance with bright flashes of Opal colour. On the body tone and brightness chart the body colour of white Opal is N8 or N9. White Opal is capable of displaying any combination of spectral colours such as red, blue, purple and greens. 

The major difference between this type of Opal and the Black Opal is that white Opal tends to have a subdued play of colour since the body colour of the stone is light. In black Opal because the body is very dark the play of colour is much brighter. 

In terms of production the white Opal is by far the most plentiful. In Australia the majority of the opal produced comes from South Australia. There are three main South Australian opal mining fields these are Coober Pedy, Andamooka and Mintabie

闪电岭蛋白石:开采于澳大利亚新南威尔士州的内陆地区黑蛋白石来自闪电岭周围的各种矿区

黑色蛋白石是指基础颜色–翻转时的蛋白石颜色。身体越黑,对石头的价值就越大。正是这种黑暗使石头中显示的其他颜色更加明亮。黑色和深色蛋白石是所有蛋白石中最稀有的,来自闪电岭的矿山。

昆士兰州博尔德蛋白石:我们的蛋白石产自澳大利亚昆士兰州内陆,矿产来自各种矿区,包括-温顿,科罗伊特,优瓦,埃罗曼加,吉达和基尔皮

巨石蛋白石是一种蛋白石类型,形成于铁石巨石腔内,始于昆士兰州中部被内陆海覆盖。蛋白石存在于垂直和水平裂缝或接缝中。它被切割,背面保留有铁石,被分类为固体蛋白石。

博尔德蛋白石(Boulder Opal)发生在昆士兰西部的一个广阔地区,从温顿北部到奎尔皮南部。博尔德蛋白石被认为是用途最广泛的蛋白石之一,因为它具有昂贵的黑色或水晶蛋白石的所有颜色和图案,但由于它包含在铁石中,因此非常耐用。

从侧面看时,您总是可以通过自然的不平线分辨出一块真正的固体巨石蛋白石,在该直线上蛋白石填满了巨石中的空隙。

 

白蛋白石 也称为乳白色蛋白石,外观为淡白色,具有明亮的蛋白石色闪光。在身体色调和亮度图表上,白色蛋白石的身体颜色为N8或N9。白蛋白石能够显示光谱颜色的任意组合,例如红色,蓝色,紫色和绿色。

这种蛋白石与黑蛋白石之间的主要区别在于,由于石头的主体颜色较浅,因此白色蛋白石往往具有柔和的色彩。在黑色蛋白石中,因为身体非常暗,所以色彩的发挥要明亮得多。

就产量而言,白色蛋白石是迄今为止最多的。在澳大利亚,生产的大多数蛋白石来自南澳大利亚。南澳大利亚州有3个主要的蛋白石采矿场,分别是Coober Pedy,Andamooka和Mintabie
