The color Of the ruby Is another q
= mysteries. and one upon WIKI Prof
Judd was only able 10 touch upon
slightly n his lecture. The color IS
distributed most irregularly and some
c0rundum crystals show in patches the
tinis Of the ruby. the sapphire and the
emerald all mixed tOge;her- These
oolors are. Of course. due 70 the special
way in which the structure Of the crvs-
tai deals with the light passing through
il, the ruby absorbing all the rays ex-
eept those which emerge to give il its
characteristic color.
How greatly these eolors iepend on
molecular and chemical changes going
on in the crystal is obTious from the
strange way some gems behave under
light and heat. Prof. Msskel7ne men
tons a diamond which, when taken ont
otthe warm pocket and allowed TO cool
on the table, turned a beautiful red.
Prot Judd startled his audience BY de-
clariug that the green glass panes used
in the eonseryatories al Kew gradually
changed through varions shades of vel
low 10 q distinct purplish hue under
the prolonged action of light.
Rubies change their color in a cur
ious way under the action OF heat.
Blush rubies turn perfectly green. aud
on cooling regain their original tint.
The blue sapphire turns white. and the
yellow corundum crystal becomes
green. Then there is the strange prop
erty Of ''pleochroismH in the ruby fam
lily aud its kindred; they exhibit differ
ent tints. according 10 the size of the
