Advantages of k gold
(1) with rich colors
K gold is 75% gold doped with 25% other metals, so it will appear in different colors, such as white 18K gold, rose 18K gold, yellow 18K gold and so on. It is fashionable because of its rich colors.
However, the diamond ring holder is made of white and rose.
2 the price is cheap.
Because it contains 25% other metals, the purity is not high, so the price of 18K gold is more affordable.
③ High hardness.
K gold has high hardness and is not easy to deform. When used in diamond ring design, it can flexibly show the modeling creativity of the ring, and can make relatively complex diamond ring styles more than platinum.
In particular, as a ring holder for large carat diamond rings, its supporting force is stronger than platinum, which can firmly protect precious diamonds and prevent them from falling off and causing losses.
Advantages of platinum
(1) does not fade
Platinum will not fade, because it is a pure natural metal, without any alloy, and it can always maintain a natural silvery white color, setting off the fire color of diamonds to the greatest extent, which is very beautiful.
2 expensive.
As a pure natural precious metal, platinum is scarce in resources, and its exploitation is only 5% of that of gold, so it is normal for platinum to be expensive.
③ Strong toughness.
Platinum has strong toughness and memory, especially toughness. One gram of platinum can stretch out 2000 meters of platinum wire to make different textures.
