(1) Sapphire is a 9 on the Mohs scale of hardness, so extremely durable and scratch resistant. Synthetic sapphires are lab-created but obtain the same physical, optical and chemical properties as natural sapphires. Since they have the same properties as naturals, they will not scratch or chip more easily than a natural stone.
(2) Silver jewelry is easy to look after. The best way to keep your silver looking great is to wear it on a regular basis as this stops it oxidising with the air and tarnishing. We recommend you store your silver jewelry in a soft pouch to prevent scratching when not worn. Avoid contact with perfume, hairspray and cleaning products to maintain the shine.
Obe of the best cleaning methods, is to use aluminum foil to clean your tarnished silver jewelry much like you would your silverware. Line a tray with a piece of crumpled aluminum foil and place your jewelry on the foil. Sprinkle a layer of baking soda over the jewelry, then pour boiling water over it. The tarnish will transfer from the jewelry to the foil. You may need to flip or move the jewelry around so all sides come in contact with the foil. Remove and rinse with water.
(3) The center stone is this ring is approximately 6ct tw. The accent stones are approximately 1.8ct tw.
