A pearl is hard object found in the soft tissue of a living shelled mollusc. Just like the shell of clams, a pearl is made up of calcium carbonate. The ideal pearl is perfectly round and smooth, but sometimes many other shapes may occur.
The definition of a pearl is, a hard smooth lustrous typically rounded structure occurring on the inner surface of the shell of a clam or oyster. Before the creation of cultured pearls in the early 1900s, natural pearls were so rare and expensive that they were reserved almost exclusively for the noble and very rich. Unlike gemstones or precious metals that must be mined from the earth, pearls are grown by live oysters far below the surface of the sea. Pearls are the only gemstone made by living animals. Pearls take their color from the inside of the shell in which they are growing. They range from white to gold, and from purple to black. The molecular formula of a pearl is CaCO3
“Again, the kingdom of heaven is like a merchant in search of fine pearls, who on finding one pearl of great value, went and sold all that he had and bought it.” Matthew 13:45-46
This illustration could be used to show that someone who truly appreciates God's Kingdom will act like that merchant. A person that would give up everything in life for the kingdom of heaven.
I chose this molecule because Pearls have always interested me. I find incredible how these little jewels are made in the bottom of the ocean by clams. Pearls are also the birthstone of June, which is the month that I was born in.
