The Classification of Baltic Amber (succinite) Gemstones

The IAA has developed the following classification of amber gemstones, which it uses in relation to the companies it recommends. The classification also applies to finished amber products, which should not contain a mix of elements listed in different categories:

Amber, natural amber (succinite): natural amber, subject only to mechanical treatment (for instance: grinding, cutting, turning and polishing) without any change to its natural properties.

Improved amber (succinite): semi-finished products or products of Baltic amber, in which changes to its physical properties, including clarity and colour, have been artificially induced using thermal treatment.

Amber doublets, triplets or multi-element Baltic amber: gemstone consisting of two or more pieces of which at least one must be natural or improved Baltic amber. A coloured layer made of durable material between the amber elements or the placement of the formed amber gemstone on a base made of another material is permitted.

Reconstructed (pressed) Baltic amber: gemstone made of small amber grains and/or amber meal pressed in high temperatures and under high pressure without additional components.

Amber (succinite) imitations: materials, semi-finished products or products made of substances similar in appearance to Baltic amber (succinite), but with different physical and chemical properties. Any unlabelled imitation is a forgery.

Note: In order to underscore or change the natural colour of amber, it is permissible to use foil or flakes made of precious metals and colour backdrops made of enamel or paint in jewellery products decorated with Baltic amber (succinite) gemstones.

The above classification was adopted by the International Amber Association’s Expert Commission on Qualification at its session of 9 May 2005.

不逐句翻譯了，只翻譯一些關(guān)鍵的。如翻譯的不對，請多指正。

Amber, natural amber (succinite): natural amber, subject only to mechanical treatment (for instance: grinding, cutting, turning and polishing) without any change to its natural properties.
琥珀，天然琥珀：天然琥珀只接受過機(jī)械處理（如：磨，切，turining?，拋光），沒有任何的自然屬性改變。

Improved amber (succinite): semi-finished products or products of Baltic amber, in which changes to its physical properties, including clarity and colour, have been artificially induced using thermal treatment.
改良（優(yōu)化）琥珀：琥珀成品或半成品，被人工的通過熱處理的方式誘導(dǎo)使之發(fā)生物理性質(zhì)的改變，包括透明度和顏色。

Reconstructed (pressed) Baltic amber: gemstone made of small amber grains and/or amber meal pressed in high temperatures and under high pressure without additional components.
再生琥珀（壓合）：由小琥珀碎塊和/或者琥珀粉在高溫高壓下壓制，不添加其他成分。

Amber (succinite) imitations: materials, semi-finished products or products made of substances similar in appearance to Baltic amber (succinite), but with different physical and chemical properties. Any unlabelled imitation is a forgery.
琥珀仿品：原料，半成品或成品由近似琥珀的物質(zhì)構(gòu)成，但是物理和化學(xué)性質(zhì)不同，但是沒有標(biāo)簽說明是仿品的。

Note: In order to underscore or change the natural colour of amber, it is permissible to use foil or flakes made of precious metals and colour backdrops made of enamel or paint in jewellery products decorated with Baltic amber (succinite) gemstones.
備注：為了強(qiáng)調(diào)或者改變琥珀的天然顏色，在珠寶首飾中允許使用貴金屬的薄襯片和瓷漆或油漆的有色背景布來修飾琥珀。
