The main component of 750 gold is gold, the hardness of gold is 2.5, and the hardness of platinum is 4-4.5, so normally speaking, platinum hard, but because 750 gold is 75%pure gold added 25%of other precious metal elements, increased gold, which increases gold. Hardness reduces its melting point and changes its color, so the stability of 750 gold is very good, and the diamonds are not easy to deform, so that the diamond is stronger. Of course, it is not that the platinum inlaid is not firm, but the platinum is higher. The ring will be higher than the probability of deformation of 750 gold during wearing.
In fact, everything is two-way. You choose platinum if you choose not to fade, because platinum is the rare precious metal, and the hardness is 4-4.5. If you choose the stylish and firm style, choose the gold 750 because it belongs to it belongs to it Metal precious metals, strong plasticity! However, people in developed countries in Europe and the United States like to use K gold very much. They don't want a lifetime.
The 750 inlaid diamonds are more firm. Relatively speaking, the 750 inlaid is more cost -effective. Although it will be yellowed if it is worn for a long time, just plated it. Services are important.
The stability of 750 gold is better, so the safety factor of inlaid diamonds is higher, and the cost is lower, so two diamond rings of the same size, platinum inlaid
Platinum and diamonds are a perfect match. It refers to the common PT950 inlaid with a purity of 95%. The K gold is 18K and the gold content is 75%. PT is more pure.
In absolute hardness, K gold's hardness is larger than platinum.
