Transpiration in plants is roughly like breathing and perspiring for us; water taken up through
the roots is expelled as water vapor through stomata on the leaves. The stomata are pores
that open and close to enable the diffusion of carbon dioxide within the leaf while
water vapor escapes out. The transpiration cools the plant as well as changing the osmotic
pressure within the cells and transporting mineral nutrients from the roots to the shoots.
Because of capillary action of the water, this hydraulic system of nutrient transport and pressure
modulation is efficient, though the cost is the water itself in the form of water vapor (which
is why plants wilt without it!). The combination of light green emerald and deep blue
sapphire made me think of the ongoing exchange between water and leaf. Most strands of emeralds
are a deeper green, but I found the mix of lighter stones adds lightness and airiness to
the piece. Emerald is a beryl, a cyclosilicate in which Sally Silica Tetrahedra connects at corners,
forming rings, and sapphire is a corundum, a close-packed oxide with metal or semi-metal atoms and
lacking Sally; though different in composition, both gemstones are hard (Mohs hardness of 8+)
and treasured for their beauty and resilience.
