Titanium crystal is the best crystal, which is produced in Brazil and has stopped mining.

The crystal must be transparent.

The gold thread inside had better be as smooth as possible.

I bought a string of hand beads the other day. The crystal is very transparent, and every gold thread is smooth.

Yes, it is rare. The only drawback is that the crystal is too small, worth 500 yuan.

I saw a necklace in Jewelry Street yesterday. The one in the middle is good, crystal.

Well, there are many gold threads, and they are very smooth. The first few pieces of Xianglian are of good quality.

It's not good to look at the back carefully. I demand a price of more than 6000 yuan.

The gold wire of titanium crystal is flat, and there is another kind called hair crystal, which is slightly lower than titanium crystal.

The gold thread on the surface is thinner and cylindrical like hair.

Watch it again.
