"Isaiah54:11-12" & "Formation of Gems&Pearls"
GEMS

Isaiah 54:11-12
11 O thou afflicted, tossed with tempest,
and not comforted,
behold, I will lay thy stones with fair colours,
and lay thy foundations with sapphires.
12 And I will make thy windows of agates,
and thy gates of carbuncles,
and all thy borders of pleasant stones.

Matthew13:44-45

-One of the principles of crystalization:
"As the temperature of a liquid drops, the amount of solid ingredients it can
hold in suspension drops as well."
-" it takes the proper combination of pressure and temperature for
minerals to crystalize."
-"Two other conditions are needed for crystalization; time and space."
& "They all need room to grow."
-" The chemical rich fluid supplies the necessary ingredients &
The cavity offer space to grow,and the temperature and pressure are
high."
"As the fluid moves through the crust, it cools enough for cxrystalization to
occur."
"=Time is required.
-...This is a highly tumulutous environment:
・ The passages are constantly opening and collapsing.
・ Often crystals start to form, and then the passage feeding the
fluid is closed off.
・ At this point, all growth stops.
・ -If the passage reopens, growth will begin again. "
" Often this on and off growth pattern is undetectable in a
crystal."
"At other times, the successive layers of growth will have a slightly
different chemical composition.
When this happens, you see colour zoning in the crystal.
-In some occasions, the new layers will have different orientation.
This is the cause of twinning.
Still other times, the new layers will not bond completely with each other.
When you see parting on s star ruby, it is because the layers did not
bond."

"How do oysters make pearls?"
- HowStuffWorks

As the oyster grows in size, its shell must also grow.
The mantle is an organ that produces the oyster's shell, using minerals from
the oyster's food. The material
created by the mantle is called nacre. Nacre lines the inside of the shell.
­The formation of a natural pearl begins when a foreign substance slips
into the oyster between the mantle and the shell, which irritate­s the
mantle. It's kind of like the oyster getting a splinter.
【 => Re: "2 Corinthians 12:2-10; " = Blogger's Insertion 】
The oyster's natural reaction is to cover up that irritant to protect itself.
The man­tle covers the irritant with layers of the same nacre substance
that is used to create the shell.
This eventually forms a pearl.

So a pearl is a foreign substance covered with layers of nacre.
