—————————— Strong dividing line—

First of all, we should make clear the original intention of the landlord's question.

1. If the "gem" asked by the landlord is marked on the watch dial or other information about how many diamonds, please correct it here. The so-called watch 2 1 diamond, 23 diamond (2 1 gem) and so on. , indicating that there are 2 1 or 23 key parts (bearings, etc. ) made of precious stones on the movement of a watch, whether it is inlaid with precious stones or not. In addition, the so-called "a few diamonds" and "a few gems" are definitely not diamonds, but generally "rubies". And now the movement is basically made of artificial gem, which was natural when there was no artificial gem technology before.

2. If the "gem" asked by the landlord refers to some jewelry watches (watches with gem ornaments embedded or encapsulated in bezel, dial, strap, etc.), there is no way to give a general answer to explain whether his gem is true or false. Even watches with their own carriers are true and false, and the authenticity of gems is even more important. As for the choice of gems, it mainly depends on personal preferences. The greater value of jewelry watch itself should be said to lie in its luxury and decoration, rather than practicality.
