Kyara - The highest grade of Aloeswood is called Kyara, which means "Precious" in ancient Japanese. Kyara has deeper aroma and is more resinous than the average Aloeswood, and it is more expensive per ounce than gold.(by Shoyeido).
Kyara is Sanskrit for Black, and kyara is the most precious aromatic resin in the world. It is the higest regarded of all Jinkoh (aloeswood). The word "jin" means sinking in water, and Jinkoh coming from the Sanskrit, means: "Heavy." This dense, heavy resin is very rare and can only be found in a few southeast asian countries. (by Baieido)
