Pararescuemen are known as PJs, for Pararescue Jumpers. They hold a very unique position as USSOCOM (indeed all of DODâs) only specific CSAR (Combat Search and Rescue) career field, trained and equipped to conduct both conventional and unconventional recovery missions, CASEVAC and MEDEVAC. They are not simply medics, and they are anything but unarmed.
This weight (one carob seed) as later standardized to be 1 carat, or 1/5th of a gram, hence a five carat diamond equals 1 gram and 155.51 carats equal one ounce. The one carat weight is then broken down into 100 equal parts called points; 75 points equal 3/4 of a carat, 50 points equal 1/2 of a carat, etc. The significance of the weight is like the other quality grades. Rarity, now by virtue of the diamonds size and weight.
The larger the diamond, the more rare it is. A carat (equivalent to 200 milligrams) consists of 100 points. Therefore, a diamond of 75 points weighs .75 carats. It is important to remember that two diamonds of equal carat weight may have dramatically different values, depending upon the stone's cut, clarity and color.
