Pure gold is a bright yellow color and does not tarnish or corrode, so you can identify it by its color and shine. Additionally, pure gold is very malleable and can be easily bent or molded. You can also look for markings on the gold jewelry or item indicating the gold purity, such as "24K" or "999."
To determine if a diamond is real, you can conduct various tests such as the fog test (breathe on the diamond and see if the fog clears quickly), the reflection test (see if the diamond refracts light uniquely), and the scratch test (diamonds are one of the hardest substances on Earth and can scratch glass). Alternatively, you can have the diamond evaluated by a professional jeweler or gemologist.
Your question assumes that a diamond has changed hands for money. Many important diamonds, however, have never been sold, but have been owned based on the stone being a spoil of war or a gift to royalty.The 'most expensive diamond' may be in regal crown jewels owned by a nation state. The British and Thai crown jewels are examples of magnificent diamonds held this way. Because they have not changed hands for money, there are essentially and otherwise priceless.There are, however, a few examples of expensive diamonds, some with their record per-carat prices:The world's most expensive diamond -- 35.56 carat Whittlesbach blue -- sold for $24.3 million, beating a previous record of $16.5 million for a 100-carat diamond in 1995.The DeBeers Millennium Star DiamondThe Taylor-Burton DiamondThe CentenaryCullinan (never sold, gifted to the British Crown)Hope DiamondA 7.03 blue diamond sold for £6m ($9.5 million) in March 2009 in Geneva.Chopard blue diamond ring for 16,260,000 dollars. It has a 9-carat blue diamond, more white diamonds, and a 18k white gold setting. (In general, blue diamonds are the among rarest and most expensive diamonds in the world.)
To determine if diamond stud earrings are real, you can have them professionally appraised by a gemologist. Real diamonds will have characteristics such as clarity, color, carat weight, and cut that can be assessed by an expert. Additionally, you can look for markings such as a 10K, 14K, or 18K stamp on the earring post, indicating the type of metal used in the setting.
