Aaron’s Ceremonial BreastplateAaron’s Ceremonial Breastplate"Fashion a breastpiece for making decisions—the work of a skilled craftsman. Make it like the ephod: of gold, and of blue, purple and scarlet yarn, and of finely twisted linen. It is to be square—a span long and a span wide—and folded double.

Claimed that the twelve stones on Aaron’s breastplate symbolized the 12 months of the year, not the 12 tribes.

The Hebrew calendar contains either 12 or 13 months in a year.

Diamonds would be moderately expensive for the same reasons other gemstones are (beauty, rarity, tradition, etc.)

However, the price of diamonds is artificially high due to the blatant and highly successful manipulation of the world’s largest diamond conglomerate: DeBeers.

The company maintains a virtual monopoly on jewel-quality diamonds, controlling the supply to keep the price high.

The company also has a series of highly successful marketing campaigns (e.g., “a diamond is forever”) to keep demand high.

Besides their questionable business practices, DeBeers:

DeBeers and Injustice in AfricaDeBeers and Injustice in Africa

Officially “rejected” apartheid in South Africa, but exploited the system to the benefit of the company (although not the workers).

Continued to engage in apartheid practices at its South African mines long after the apartheid government fell.

Supported the forced removal of the Basarwa people from their traditional lands in Botswana, virtually ensuring the destruction of their culture.

Human Rights Abuses by RUF (Sierra Leone rebel group) “Some of the atrocities committed by the RUF rebels were unthinkable. Infants and children were thrown into burning houses, the hands of toddlers as young as two were severed with machetes, girls as young as eight were sexually abused, and hundreds of children of all ages were traumatically separated from their communities and forced to walk into the hills with strangers whom they had seen kill their family members. In some cases children, many of them originally abductees, participated in the perpetration of these abuses. Child combatants armed with pistols, rifles, and machetes actively participated in killings and massacres, severed the arms of other children, and beat and humiliated men old enough to be their grandfathers. Often under the influence of drugs, they were known and feared for their impetuosity, lack of control, and brutality. http://www.igtlj.com
