Chemical composition: Pure diamond is the only known gem composed of single chemical element carbon.

Atomic structure: every four carbon atoms are bound together by valence bonds of electrons around one carbon atom. The binding angles of the four carbon atoms are the same, and the bond length is extremely short (0. 154nm), so diamond is the hardest substance known.

Stability: Under normal circumstances, diamonds are not affected by acid or oxidation.

In daily maintenance, the diamond ring only needs to be cleaned once a month, because the diamond ring is sticky to oil, so there is no need to worry about the diamond ring being scratched.

Gold is a simple form of chemical element gold (chemical element symbol Au), which is a soft, golden yellow and corrosion-resistant precious metal.

Although gold is a very soft metal, it is not as good as lead and tin. Nails can be used to draw marks on pure gold, which makes gold very easy to process. But this is not ideal for the manufacturers of decorations, because it is easy to scratch the decorations, make them lose their luster and even affect their appearance. Therefore, when gold is used to make jewelry, copper and silver are usually added to improve its hardness. Gold is easy to forge and extend, and can be ground into transparent and green gold foil with a thickness of 0.001mm. 0.5g of gold can be drawn into160m long gold wire.

Maintenance of gold rings: The most important thing to preserve gold rings is to keep them shiny. Put the gold ring in the box to avoid being scratched. It can be wiped with ordinary paper towels to protect its luster.

Therefore, if you wear a diamond ring and a gold ring on adjacent fingers, the gold ring will be scratched.
