Hi there
I can't recall Master Lin saying anything particular about Jade other than that he personally selects the Jade in China that is used in making the pendants.
From my well worn book called "The Secrets of Crystals" - by author Shani Toder - is the following information about Jade.
The jade group includes Jadeite and Nephrite - both have different chemical composition - jadeite is of higher quality than nephrite, which is sold as inexpensive jade or used as an imitation of the jaedite.
Jadeite (jade) is known as the "dream stone" and enables learning through dreams and understanding them, encourages physical understanding of dreams.
Beams love, courage, chastity, justice and wisdom. Reduces negativity. Increases ability to express oneself. Balances the heart emotionally. Heals, purifies and provides comforting energy. Provides endurance and peace when worn. Calms and may bring one to a level where the body may heal itself. Increases flexibility.
Strengthens the heart, the kidneys and the immune system. May heal the eyes and can help deal with mental problems. Helps purify the blood. Encourages long life.
Jadeite (Jade) was also thought to be a magic stone providing protection and success even during hard times. It has the ability to improve relationships by strengthening and understanding mutual goals. Therefore recommended for use to strengthen unity in groups.Strengthens the skeletal structure and eases pains in arms and legs. May reduce and lighten scars.
Nephrite (Jade) was thought to be a holy stone that provided protection against negativity. Balances duality in the energy including masculine and feminine energies. Adjusts metabolism. Increases flexibility. Calms and strengthens the heart area physically and mentally.
Both are very impressive and I can understand why Master Lin would choose this particular crystal to support his work.
Hope this helps
