These imitations can be either synthetic or natural. (Synthetic diamonds, on the other hand, have the same chemical composition as real diamonds and are not considered fake.) A loupe is a magnifying glass that you can buy at any jewelry store and will let you take a closer look at your gem and setting. The majority of diamonds are made in nature so that means you?re going to see some imperfections. A fake stone would be absolutely perfect. Most of our Diamond Alternatives are Austrian Zirconia (99.99% of the time) but are not limited to this type of stone and may vary depending on availability. 925 Sterling silver is a great option because it's durable and long lasting, so it's good for rings, necklaces, bracelets, cufflinks, belt buckles, body jewelry... you get the picture. But keep in mind that silver jewelry is softer than gold, platinum and titanium, and it's likely to tarnish without proper care. Do not store jewelry in the bathroom. Keeping pieces stored in individual plastic bags will help prevent oxidation and scratches. Store outside of the bathroom to avoid the steam and humidity dulling or rusting them prematurely. ... The humid environment will speed up the oxidation process and cause jewelry to tarnish faster. "The accumulation of dirt, bacteria, oil or fogging in jewelry can affect your skin," says Dr. Peredo of Quora... But there is at least one good reason not to sleep on your jewelry. "Wearing your jewelry while you sleep is the number one cause of losing precious stones and abrading the barbs!"
