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 carat weight measures the mass of a diamond. One carat is defined as 200 milligrams (about 0.007 ounce avoirdupois). The point unitâequal to one one-hundredth of a carat (0.01 carat, or 2 mg)âis commonly used for diamonds of less than one carat.All else being equal, the price per carat increases with carat weight, since larger diamonds are both rarer and more desirable for use as gemstones.A poorly cut 1.0 carat (200 mg) diamond may have the same diameter and appear as large as a 0.85 carats (170 mg) diamond.) The depth percentage is the overall quickest indication of the quality of the cut of a round brilliant. Ideal round brilliant diamonds should not have a depth percentage greater than 62.5%.
