Not just any Sandalwood:
Old Mountain Sandalwood from Lotus on Water. Old Mountain sandalwood leeches on very pungent weeds and other plants for survival, and before they can be harvested, they must be allowed to grow as such for at least 80 years. Still, they are extremely smelly.
It has to be put aside for another 20 years for fermentation to bring out the beautiful sweetness in the sandalwood scent. During this process, the energies accumulated over its growth of more than 80 years are converted, locked-in and ready to contribute. Then, we carve them. Into pendants, into statues, into beads.
For most of the sandalwood if you happen to bump into any outside, no one has 80 years to spare to wait for the tree to grow, and definitely not 20 years to see the log lay there as it accumulates power. They are usually perfumed. Or, they are simply normal wood and perfumed with chemically-produced sandalwood scent.
