What is Silver?
Sterling silver is 92.5% silver and is sometimes referred to as pure silver. Sterling silver will tarnish over time but with care and regular cleaning can be restored to its good as new sparkling condition. The remaining 7.5% is usually copper but can be other metal and is used to give this precious metal strength and durability.
Generally, the higher the silver content the brighter or whiter the metal but beware of antiquing effects that can make a piece of sterling silver jewellery or decorative silverware look dark. Silver which is 99.9% silver is too soft to be practical for most day to day uses. Do not use tissue or anything other than a jewellery cleaning cloth to polish your jewellery as unseen tiny hard fibers will scratch the surface.
A perfect diamond has no flaws
A perfect diamond has no flaws. In valuing diamond, Diamond clarity is one of the important features. Most of the 20 percent that are gemstone quality still have significant flaws.

A gemstone is a stone that is beautiful
A gemstone is a stone that is beautiful, rare, and durable resistant to abrasion. Today, finer gemstone specimens are available to the average person than at any time in history.
Nowadays such a distinction is no longer made by the trade. Rare or unusual gemstones, generally meant to include those gemstones which occur so infrequently in gem quality that they are scarcely known except to connoisseurs, include andalusite, cassiterite and bixbite. Some minerals can be very beautiful, but they may be too soft and will scratch easily (such as the mineral fluorite). Fluorite is extremely colorful and pretty but has a hardness of only 4 on the hardness scale and has four perfect cleavage directions, which makes it only an oddity as a cut gem.
