Because, at least, the acquaintance with electricity, without which\nthere is nowhere, happened with the help of amber.<\/p>\n\n\n\n<p>What color should the sculpture be carved in honor of the\nancient companion of mankind? Honey, say adherents of the classic amber\nvariety. Green, will be clarified by deep connoisseurs of beauty &#8211; and they\nwill be right!<\/p>\n\n\n\n<p>Green amber is rare and uniquely beautiful. But what kind of\ngreen amber are we talking about? Let&#8217;s try to figure it out.<\/p>\n\n\n\n<p>Different greens of different amber<\/p>\n\n\n\n<p>The lion&#8217;s share of amber mined in the Baltics, central and\nnorthern Europe is honey-yellow. In some cases, the mined stones turn\ndistinctly green &#8211; retaining, however, a yellow or yellow-brown hue.<\/p>\n\n\n\n<p>Mineralogists explain such color deviations by special\nconditions of &#8220;storage&#8221;. Some specimens of newly formed amber, on a\nwhim of fate, fell into swampy water full of decaying organic matter. And they\nspent enough time in them for the interaction of tree resins with nitrogenous\ncompounds.<\/p>\n\n\n\n<p>As a result of slow natural nitrogenation, ordinary honey\namber acquired the color of a dead grass. Such greens are far from emerald\ngreen, but greenish European amber is in demand: after all, they are beautiful,\nand even rare &#8230; Curious samples of fossil resins are mined on the island of\nSicily. Most of them are red, some cast an obvious blue, sometimes with a\nnoticeable green tint. Even more beautiful stones were once dug in the lignite\ndeposits of Saxony: they were distinguished by their transparency and\ngolden-green color. However, all European green amber \u201cfade\u201d before Dominican\namber.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The most beautiful and expensive<\/strong><\/h2>\n\n\n\n<p>Nature decreed that the tree resins, fossilized in the\ngeological conditions of the island of Haiti, became similar to the marine\nenvironment. The massif of stone is similar in color and transparency to sea\nwater. Frequent foreign inclusions imitate sandy mounds and bottom vegetation.<\/p>\n\n\n\n<p>Some of the Dominican amber is more blue than green. But the\nmost beautiful and most expensive are famous for their beautiful green color\nwith a slight bluish tint. The cost of the best copies can be calculated in\ntens of dollars per gram.<\/p>\n\n\n\n<p>Fortunately, local miners of green amber are not prone to handicraft damage to the stone, and they do not really like to grind gaudy figurines from precious materials. However, if you find yourself in the shopping streets of Santo Domingo, shopkeepers will try to foist you on stale illiquid assets. Feel free to bargain, dropping the price five to ten times, and then in any jewellery workshop in Europe, roughly hewn skulls and figurines of chimeric insects will be turned into decent cabochons by your order.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>High price as an incentive for chemical creativity<\/strong><\/h3>\n\n\n\n<p>Emperor Nero gave a young and strong slave for a small piece of green amber. Therefore, even in ancient antiquity, artisans got the hang of turning ordinary amber into the green. Most of the stones cracked from heating in unrefined olive oil, but the color of the amber shards changed to green.<\/p>\n\n\n\n<p>A good effect is also observed with dry heating of amber\nunder conditions of limited oxygen access. The heated stone is tightly wrapped\nin foil and placed in the oven. After processing, the amber becomes glassy and\nliterally shines with a golden-green color.<\/p>\n\n\n\n<p>To enhance the chromaticity, medieval craftsmen came up with the idea of \u200b\u200bprocessing the lower side of jewellery inserts hidden from the user with a dye paste. Green substrates for warm amber were also practised.<\/p>\n\n\n\n<p>In modern conditions, green amber is produced everywhere. The difference in the chemical composition of amber mined in different deposits determines the variety of stone processing technologies. A multistage exposure is used in heated gaseous and liquid media. The saturation of fossilized resins with metal ions is carried out. Intense irradiation with a hard electromagnetic spectrum makes it possible to achieve the effect of luminescence in the thickness of the stone.<\/p>\n\n\n\n<p>Researchers, however, note that the most attractive green\ncolor of amber is obtained not by the introduction of impurities, but by\nhigh-temperature exposure. Atomic aggregations arising under the influence of\nhigh temperatures change the light transmittance of the resins. The longest\nwavelengths (red) are absorbed, and the light passing through the array\nacquires a green tint.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Fully artificial imitations of green amber<\/strong><\/h4>\n\n\n\n<p>Modern imitations of green amber are devoid of any\ndisadvantages inherent in processed natural stone. If heated Baltic amber\ncracks with its characteristic internal \u201cconfetti\u201d and acquires a rusty-green\nhue, then bernite and blizzard shine with emerald beauty, are distinguished by\ntheir strength and durability.<\/p>\n\n\n\n<p>Constant replenishment of the market for polyester resins, cured with special additives or ultraviolet radiation, opens up great opportunities for green amber counterfeiters.
