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.

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 quality of a diamond's cut is widely considered the most important of the four Cs in determining the beauty of a diamond; indeed, it is commonly acknowledged that a well-cut diamond can appear to be of greater carat weight, and have clarity and color appear to be of better grade than they actually are.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%.
