6 grams of oval sapphire has a size of 12 mm and a height of 7 mm. The weight of a carat diamond is 0.2g, and six carats is 1.2g, which is six times the weight of a carat diamond. From the visual dimension, a six-carat diamond is not six times that of a carat, with a diameter of 6.5 mm and a height of 3.9 mm, while a six-carat diamond has a diameter of 12 mm and a height of 7 mm, which is equivalent to twice that of a carat diamond.

Maintenance of sapphire

Sapphire is a kind of gem with strong adsorption. After wearing it for a long time, you should take it off and clean it in time, and wipe it with a soft cloth dipped in water. The preservation of sapphire also needs great attention, and it is best to keep it alone to prevent contact with other jewelry from damaging the polished surface of sapphire.

Pay attention to acid-base corrosion. Some substances we come into contact with in our daily life or food contain different concentrations of acid or alkali, and these different concentrations of acid-base chemicals may damage gems. The use of cosmetics in daily life should try to avoid being polluted by jewelry.

Wear makeup and perfume before wearing jewelry on weekdays to avoid high-concentration cosmetics or perfume directly contacting the surface of jewelry. If you need to replenish perfume, you should also avoid spraying perfume directly on the surface of jewelry.

The inlaid sapphire jewelry should be checked regularly to see if the inlaid claws are loose. Try not to use ultrasonic cleaning when cleaning to prevent the inlaid place from loosening under high-frequency vibration!
