(1) Couleur. The best emerald color is that strong emerald green with a little blue tone, that green will make people unforgettable. Positive green and slightly yellowish grass green are also very good, while dark green and light green are inferior colors.
(2) Clarté. The clarity of emeralds is generally not very good, with large and small fissures and other internal inclusions common. Donc, when evaluating the clarity of emeralds, the requirements should be appropriately reduced, and the obvious inclusions invisible to the naked eye shall prevail.
(3) Transparence. The transparency of emeralds is good or bad. Some are very transparent, clair et transparent; some have poor clarity, and the entire gem looks hazy. Bien sûr, those with good transparency are top grades, and those with poor transparency are inferior products.
(4) Cut work. The emerald cut is specially designed to reflect emeralds, which are mainly colored gemstones with brightness as a supplement, and conform to the characteristics of emerald gemstones that are more brittle. Donc, the preferred cut style for emeralds and similar other beryl gemstones is the emerald type. The refractive index of beryl gemstones is low and it is difficult to produce total internal reflection light. Donc, the pavilion of the gemstone does not have to be very thick, but a pavilion that is too deep will make the gem of a small size look thick.
(5) Qualité. Emerald rarely exceeds 10 ct, and high-quality products exceeding 2 ct are rare. Most faceted gems are less than 1 ct.
(6) Special optical effects. Starlight emeralds require beautiful star lines, and other aspects are not demanding.
Emerald cleaning and maintenance:
Emerald has poor toughness and strong brittleness. It cannot be cleaned in an ultrasonic cleaning machine. It cannot be stored with other jewelry to prevent damage. It cannot be worn or stored at high temperatures. It must be waxed and polished at a jewelry store regularly.
