what is synthetic opalOpal is a naturally-occurring amorphous solid known for its flashes of fire color. An amorphous solid is a material that, unlike crystal, is not organised in a regular lattice pattern. This makes for some unusual interactions with light, and is explicable for opal’s rainbow colours. 

However, just because opal is classified as amorphous is not to say that its atoms are arranged without order. Chemists have discovered a clear sphere structure in opal, which has led to them copying it in 1974. Synthetic opal is often named Gilson opal, after Pierre Gilson, the man who invented it (along with a number of other synthetic minerals: coral, emerald, lapis lazuli, etc.). If you’re looking for someone to blame for having paid over the odds for a synthetic substance, by the way, Pierre Gilson is the man you’re looking for.

 

Originally synthesised in Switzerland, Glison opal is now primarily synthesised in Japan (by Kyocera and Inamori, for example). It differs from natural opal inasmuch as it is much more regular. Synthetic opal, though less desirable than organic opal in the eyes of most lapidaries, is not to be confused with imitation opal, which, unlike pure synthetic opal, is tinctured with minerals not found in actual opal. The term “Gilson opal” is usually used to refer to imitation opal, opals which are not only lab-created but contain minerals not found in actual opal (minerals such as plastic in Slocum stone, for example).

How to Spot a Synthetic Opal

If you ever find yourself in the market for opals, you’d be well advised to bring a loupe along with you. Under a high magnification (of around sixty), it’s clear to tell by the regularity and columnar nature of the patterns that the opal is synthetic. Even to the naked eye, the columnar nature of the opal is plainly visible. With the help of a loupe you’ll be able to discern a so-called ‘lizard skin’ effect in the patches of colour. This crumbly surface is the most common “tell-tale” of synthetic opal.

Synthetic opals are said to fluoresce a green colour under UV light. Along with the loupe, you’d be well advised to take a UV torch along with you to the flea market (or wherever you go to get your opals). If it fluoresces, it’s synthetic; if not, it’s natural.

The Two Main Kinds of Synthetic Opal

Synthetic opal comes in two main kinds: white opal and black opal. The white opal is generally more expensive than the black, largely because the white is more natural-looking than the black.

A new man made opal Monarch opal has recently come onto the market and many people think it isa new opal, but it is man made synthetic opal.

Monarch opal has been the most confusing man-made opal so far as dark black the potch line inclusions look like treated Andamooka stone

Another man-made opal is Aurora Opal made by the German company Pinfire Gems and Colloids

These Synthetic Opals and Synthetic Impregnated Opals, Coarse and Fine Crystalline Opals have a Non-Directional Play-of-Color and are seen in lot opal bangles. They market Aurora black opal, Fire opals and Crystal opals. The Aurora opal patterns are described as Irregular and non-directional swirls.

SYNTHETIC OPAL CHEMICAL COMPOSITION: SiO2.nH2O+Resin

Many countries manufacture opals as it is a valuable gemstone, so unfortunately we will be expecting more synthetic opals to come on line. To our knowledge China and Thailand are constantly trying to manufacture new products for this market to catch the unsuspecting opal buyer. Professional laboratories try and market their product as brand name.

Synthetic opal is available in sheets or blocks. Blocks are used to make bangles and sheets are ideal for inlay work or matching sets rings, pendant and earrings.

Warning to hobby cutters, most of these man made silica opals do have the same properties as natural opals, which can cause problems with lungs called silicosis.

什么是合成蛋白石蛋白石是一种天然存在的无定形固体,因其闪烁的火色而闻名。无定形固体是与晶体不同,不以规则的格子图案组织的材料。这使得与光的一些不寻常的相互作用,并且可以解释蛋白石的彩虹色。

然而,仅仅因为蛋白石被归类为无定形,并不是说它的原子排列没有顺序。化学家在蛋白石中发现了一种清晰的球体结构,导致它们在1974年复制它。合成蛋白石通常被命名为Gilson蛋白石,在发明它的人皮埃尔·吉尔森之后(以及其他一些合成矿物质:珊瑚,祖母绿) ,青金石等)。如果你正在寻找一个因为合成物质的赔率而受到指责的人,顺便说一下,皮埃尔·吉尔森就是你正在寻找的人。

Glison蛋白石最初在瑞士合成,现在主要在日本合成(例如Kyocera和Inamori)。它与天然蛋白石不同,因为它更加规律。合成蛋白石虽然比大多数宝石眼中的有机蛋白石更不可取,但不要与仿蛋白石混淆,模仿蛋白石与纯合成蛋白石不同,是用实际蛋白石中没有的矿物质酊剂。术语“Gilson蛋白石”通常用于指仿制蛋白石,蛋白石不仅是实验室产生的,还含有实际蛋白石中未发现的矿物质(例如Slocum石中的塑料等矿物质)。

如何发现合成蛋白石

如果您发现自己进入蛋白石市场,建议您随身携带放大镜。在高放大倍率(大约60倍)下,很清楚地说明蛋白石是合成的图案的规律性和柱状性质。 即使是肉眼,蛋白石的柱状性质也清晰可见 。在放大镜的帮助下,您将能够在色块中辨别出所谓的“蜥蜴皮”效果。这种易碎的表面是合成蛋白石最常见的“告诉”。

什么是合成蛋白石

据说合成蛋白石在紫外光下会发出绿色荧光。随着放大镜,你最好随身携带紫外火炬到跳蚤市场(或者你去哪里吃蛋白石)。如果它发出荧光,它就是合成的;如果没有,那很自然。

两种主要的合成蛋白石

合成蛋白石有两种主要类型:白色蛋白石和黑色蛋白石。白色蛋白石通常比黑色更贵,主要是因为白色比黑色更自然。

一个新的人造蛋白石君主蛋白石最近进入市场,许多人认为它是一种新的蛋白石,但它是人造合成蛋白石。

合成蛋白石

君主蛋白石一直是最令人困惑的人造蛋白石,因为深黑色的potch线包含看起来像处理Andamooka石

另一种人造蛋白石是由德国公司Pinfire Gems和Colloids制造的Aurora Opal

这些合成蛋白石和合成浸渍蛋白石,粗和精细结晶蛋白石具有无方向性的颜色,并且可以在很多蛋白石手镯中看到。他们销售极光黑蛋白石,火蛋白石和水晶蛋白石。 Aurora蛋白石图案被描述为不规则和非定向漩涡。

Sanwa的Bello蛋白石是一家总部位于香港的公司,生产合成蛋白石和合成绿松石。

合成的OPAL化学组成:SiO2.nH2O +树脂

许多国家生产蛋白石,因为它是宝贵的宝石,所以不幸的是我们期待更多的合成蛋白石上线。据我们所知,中国和泰国一直在努力为这个市场制造新产品,以吸引毫无戒心的蛋白石买家。专业实验室尝试将其产品作为品牌进行推广。

合成蛋白石有片状或块状可供选择。积木用于制作手镯和床单是镶嵌工作或匹配套环,吊坠和耳环的理想选择。

对业余爱好切割机的警告,大多数这些人造二氧化硅蛋白石确实具有与天然蛋白石相同的性质,这可能导致肺部问题称为矽肺病
