Gold or platinum is a precious metal that we know more about, but for what today's jewels, or the material of the table, most of which is marked 18k gold, which is commonly 18k platinum, 18k rose gold, so what does that mean
K king, k is the initial of the foreign term karat and the complete expression is karat gold. K gold is calculated by dividing pure gold into 24 pieces. The remaining 25 per cent consists of other precious metals, including platinum, nickel, silver, gold, etc。
1. 18k gold
The jewellery of 18k means a jewellery consisting of 18 per 24ths of pure gold, 75 per cent of gold plus 25 per cent of other metal alloys. In addition to the precious value of gold, gold jewellery, which has a perfect composition, has the advantage of being proliferating, hard and colour-changing, and is used in the design of ornaments to perform complex and fine creative performances。
2. 18k platinum
White k gold is impure gold. It is a white alloy made of gold and gold or metal such as nickel, silver, copper, zinc, and its main component remains gold. Since white gold appears white, white metals are the most easily confused with platinum, but are completely different from platinum. The price of white k gold is lower than that of platinum and gold and is now widely used for jewellery production materials, all of which are pure 18 k gold。
Only platinum can be called platinum. So 18k platinum is a wrong concept. It should be called 18k white gold. 18k white k gold is a mixture of 75% of gold and 25% of other metals。
3. 18k rose gold
The components of rose gold are: pure gold copper silver/zinc. Because of their moderate composite proportions, they have the characteristics of long-scaling, hardness and colour variability, while integrating 25 per cent of the other metals, they are large in hardness, they are not susceptible to deformation or scratches, and they are applied to fine and fine gold designs, which are able to develop complex design ideas。
The k-gold is extremely plastic, and the gold is lighter than the man's hair. Typically, rose gold consists of 75 per cent of 18k gold and other alloys. The hardness is higher and the pink rose gold not only increases the colour of the coloured gems but also reflects the fineness and fineness of the metal material compared to the traditional gold and platinum. It's also in shape, with heart, olive, elliptical, pear, grandmother green。
In fact, k-gold is better suited to create than gold, because gold is 2. 5 degrees hard, soft and soft to the detriment of embedding, plastic, etc. But k-gold is different, combining other metals such as copper, silver, etc., to increase the resilience of the gold, which is sufficient. Moreover, 18k gold is the preferred gold-bearing proportion of high-end jewellery producers, as 75% is already high in gold, and 25% can be used to enhance process production by using other metals to balance precious materials with precision。
In addition to this, 18k platinum is, rightly speaking, 18k white gold, which is 75 per cent of gold and integrates 25 per cent of other metals, such as nickel, silver, copper, and the resulting white gold, the main element of which remains gold, and therefore should not be confused with the natural white platinum. Similarly, 18k rose gold is gold and copper alloys. In short, the expansionary k-gold, combined with different metals, can produce a variety of colours, no wonder for the promotion of jewels。
