The Meaning of an 11.5mm Diamond

The number 11 in Feng Shui is often considered special, as it represents the harmony between spiritual power and the positive meaning of the number 1. The number 1 symbolizes a favorable beginning and brings good omens. The doubling of the number 1 to form 11 not only means double luck but also symbolizes sublimation and success.

In Chinese, the number "5" is pronounced "Ngũ," which sounds similar to the word "Phúc." Therefore, ancient people believed that this number symbolized the "Five Blessings," which are Wealth (Phú), Nobility (Quý), Longevity (Thọ), Health (Khang), and Peace (Ninh). From this, the presence of the number 5 is believed to bring luck and prosperity.

From there, it is spread that those who own items related to both these numbers, such as an 11.5mm diamond, can have a fulfilling life with double luck and positive development. The meaning of an 11.5mm diamond is harmony and balance, creating favorable conditions for new beginnings, success, and prosperity in all aspects.
