It entirely can be with times.
The bullion consumption in China is developed so far from early 1980s, from the early stage of development to buy based on ornaments,
Focus on value preserving effect, but style, style changes little, kind are dull.The rose gold ornaments till now that develops starts largely to appear on the market, and
And growth momentum is swift and violent.Apparent can see, and the consumption idea of people pursues personalization by focusing on being worth turning to, and is particular about head
The style of decorations, technique are particular about jewellery and itself individual character, the matching of dress.Karat gold jewellery are since style is modish, various colors, price
Low, diversification, personalization style meet consumer demand, and therefore it is also continued to develop.
Gold serves many purposes in national economy, but price of gold costliness and resource scarcity.In decoration material field,
Countries in the world just strive to find its substitute material from different perspectives.People often will replace gold material, referred to as it is artificial gold or
Imitation gold copper-base alloy.Imitation gold copper-base alloy be free from gold but with karat gold color and luster multicomponent alloy, usually have with 18K gold utensils similar quite color,
Good anti-tarnishing ability, casting, processing and polishing performance.It is liked by people for Jewelry Accessories and artistic article depth
