If you’re in the market to purchase the largest round fancy vivid blue diamond in the world, you might want to book a ticket to Hong Kong for October. That’s when Sotheby’s Hong Kong has scheduled its Magnificent Jewels and Jadeite Autumn Sale, which features the spectacular Premier Blue diamond. But if you go, be sure to bring your checkbook — experts believe that this unique stone will fetch more than $19 million at auction.
The American $100 bill is arguably the most important and most used bill on the planet. Hundreds make up about 75% of the value of all cash that’s currently in circulation, and they’re incredibly popular overseas as a hedge against fluctuating local currencies. This popularity has led to widespread efforts to counterfeit what has become the gold standard of American currency. That’s why about 10 years ago, the process to redesign the bill began, with the goal of making it much harder to counterfeit.
This year, coin collectors are celebrating the release of the American Buffalo one-ounce gold reverse proof coin. Struck in 99.99% fine, 24-karat gold at the United States Mint at West Point, this beautiful coin has a style all its own. Instead of the traditional proof style — with a shiny background and frosted buffalo and Native American head — the reverse proof coin has a frosted background and shiny design elements. A reverse proof Gold Buffalo has never before been issued by the U.S. Mint, so this is something that collectors are pretty excited about.
Gold is hot these days. Prices are reaching all-time highs, which is why it is a great time to sell the gold jewelry, collectable gold coins or gold bullion you’ve accumulated over the years. If you’ve decided to sell your gold and want to get the most for it, you need to understand how the gold evaluation process works.
Get your gold tested
When you take your old jewelry to a gold buyer, the first thing they are going to do is determine the gold’s purity. They will refer to its purity in karats. The more karats in your piece, the higher the concentration of gold (and the higher the value). For example, 24 karat gold is close to 100% pure gold, while 18 karat gold is 75% gold and 25% other metals.
One way to test the purity of your gold employs electricity. The most common evaluation tool a gold buyer might use is the acid test. When nitric acid comes into contact with copper — which all imitation gold jewelry contains — it turns the metal green. So, if the metal doesn’t turn green, it’s gold. Both are simple and effective tests that can be done in moments.
Another method is called “fire assaying” and it is the gold standard in assessment. All the major refineries and gold mining companies use this method, but the process takes quite a while and requires specialized equipment.
