Why are the patented diamonds of the diamond family so popular?

The patented diamonds of the diamond family include round diamonds and octagonal diamonds. You can join the time bank program and get a free diamond every year for up to 60 years to witness the growth of love. Yam Tat-wah, the best actress, and his wife Sophia Kao were the first customers of Time Bank. On the one hand, the quality of patented diamonds is really good, on the other hand, it is quite emotional to lead the diamond every year.
