Last week we discussed the 4C that you need to consider when comparing diamond jewelry. Diamond jewelry, as some would put it, is the royalty among all gems. As such, assessing the value and quality of this gemstone had been refined to almost an exact science and a very fine art for hundreds of years now.
Today, dealing in diamonds either as an ardent admirer (wearing one) or as an astute trader of the same, one would need to be familiar with the four Cs – color, cut, clarity and carat.
With the naked eye, most diamonds would appear colorless, but they do have subtle shades of colors. Experts use the letter D (colorless) moving through all the letters all the way to Z (light yellow) in identifying them. A colorless diamond is chemically pure and structurally perfect. It lets through most of the light (perfectly transparent) and produces the most amount of brilliance. Most natural diamonds, however, are imperfect, and colorless diamonds are very rare. It is, therefore, the most expensive of all.
