When buying diamond, there are four aspects that must be considered. These are the cut, the color, the carat, and the clarity of the diamond. Of these four aspects, the most important is the cut of the diamond. Diamonds can be hand-cut or machine-cut but it does not really matter whether the diamond cutter is man or machine as long as the diamond is cut to achieve the greatest symmetry and brilliance. A diamond cut does not refer to the size or shape of the diamond. It refers to depth and width, symmetry, and polish. If the depth and width of the diamond were precisely and ideally cut, they direct light to travel deep into the bottom part and then bring back that light to shine brightly on the surface. The facets of the diamonds should be balanced and this is called symmetry. And finally, the cuts should be made through specific lines to avoid chipping off the surface.
There is also the issue of diamonds being mined in Africa to finance and support the various conflicts in this continent. Such diamonds came to be known as blood diamonds. Blood diamonds may not be suitable for a jewelry which is intended to express love. Fortunately, the reputable companies involved in the diamond industry have established a tracking system for diamonds to reveal the area where they were mined and the store where they were sold. To ensure that the diamond jewelry is in no way related to any African conflict, there must be a written guarantee that will accompany the invoice of the jewelry.
Man-made pearl-like objects are called faux, artificial, imitation, manufactured or simulated. Outside the US, they are sometimes sold under trade names like Mallorca pearls, Red Sea pearls, Laguna pearls, and so on. Manmade pearls have no value as jewels, even though these counterfeits sport a realistic appearance at very low cost. Under US law, manmade pearls can't simply be sold under trade names; they must be clearly identified as imitation.
Pearl jewelry care
Pearls are like teeth--hard, but very breakable. Perfumes, hair spray, even the body's natural oils can dull pearls' luster or cloud their brilliance. Gently wipe off your pearls after every wearing using a soft, damp cloth. If you spill, clean it immediately, especially if the pearl contacts acidic food. Use a soft cloth moistened in fresh water, followed by a separate drying cloth. Wrap pearl jewelry in a soft cloth (damp linen prevents dehydration) and store them in a separate jewelry box. Most people should have their pearls restrung about once per year.
