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:在新南威尔士州内陆开采澳大利亚黑欧泊来自闪电岭周围的各种矿区

黑蛋白石是指底层颜色 - 蛋白石翻转时的颜色。身体越深,石头就越有价值。正是这种黑暗使亮度与石头中显示的其他颜色一致。黑色和黑色蛋白石是所有蛋白石中最稀有的,来自闪电岭的矿井。

昆士兰博尔德蛋白石:在澳大利亚昆士兰州内陆开采我们的蛋白石来自各种矿区,包括 - 温顿,科罗伊特,约瓦,伊罗曼加,Jundah和Quilpie

博尔德蛋白石是一种蛋白石,形成于铁石巨石的洞穴内,可以追溯到昆士兰中部被内陆海域覆盖的时候。蛋白石可以在垂直和水平裂缝或接缝中找到。它被切割成背面留下的铁石,被归类为固体蛋白石。

博尔德蛋白石发生在昆士兰州西部的一个广阔区域,从温顿北部到奎尔皮南部。博尔德蛋白石被认为是最通用的蛋白石之一,因为它具有昂贵的黑色或水晶蛋白石的所有颜色和图案,但它包含在铁石中,使其非常耐用。

从侧面看时,您可以通过自然的不平整线告诉真正的坚固巨石蛋白石,其中蛋白石填充了巨石中的空隙。

 

白色蛋白石 也被称为乳白色蛋白石,它具有淡白色外观和明亮的蛋白石颜色闪烁。在身体色调和亮度图表上,白色蛋白石的车身颜色为N8或N9。 White Opal能够显示任何光谱颜色组合,如红色,蓝色,紫色和绿色。

这种蛋白石和黑蛋白石之间的主要区别在于白色蛋白石往往具有柔和的颜色,因为石头的颜色很浅。在黑色蛋白石中因为身体非常暗,所以颜色的发挥更加明亮。

在生产方面,白蛋白石是迄今为止最丰富的。在澳大利亚,生产的蛋白石大部分来自南澳大利亚。南澳大利亚有三个主要的蛋白石采矿场,分别是Coober Pedy,Andamooka和Mintabie
