Valueable? Meaning most expensive? Most sought after? Most durable? Rarest? Valuable can be interpreted in several different ways.
The natural varieties of Alexandrite, Tanzanite, and Paraiba Tourmaline are probably the most expensive, and rarest. The latter two are one source only gemstones, and Alex was mined out years ago. Each can fetch many thousands of dollars per carat, particularly for the larger solitaires.
I would create a list of most to least, using cost per carat, rarity, and availability as follows:
Alexandrite
Paraiba Tourmaline
Tripple A grade Ceylon or Kanchanaburi Sapphire
Tanzanite/Diamond
Triple A grade Emerald/Ruby
Salt Water South Sea Pearls
Tsavorite (green ) Garnet & Spessartite (Orange) Garnet
Tourmaline - Indicolite, Watermelon and Rasberry
Spinel
Other Beryl's (Aquamarine, Morganite, Goeshenite)
Zircon (especially blue, but red, white and golden as well)
Peridot
Cultured Pearls - at least AA grade
Common Topaz - Sky blue, Swiss blue, etc...
Garnet (red - almandine, pyrope, etc...)
Quartz- Amethyst, Citrine, Rutillated, etc...
Cubic Zirconia and other man made stones.
Of course, there are many that I've left off the list, but you asked for the most common.
Hope this gives you the answers you were looking for.

I don't know too much but seeing as you don't have any other answer yet I can tell you that with even weight the emerald is the most valuable.
