There is a beautiful misconception about diamond maintenance - diamond is indestructible. It is true that diamond is the hardest among all gemstones. However, it is still prone to damage and cracks if it is poorly maintained.
Therefore, one should pay special attention when storing a pair of earrings. When two hard diamonds rub against each other, it is very possible that they will scratch each other. Therefore, the pair of diamond earrings should be placed separately in a felt-lined jewellery box. Diamond rings, necklaces and bracelets should also be wrapped in soft cloth pouches and stored separately. The hardness of other gemstones or pearls is lower than diamonds and should be stored the same way to avoid scratches.
