When the news came out that Ben Affleck gave Jennifer Lopez a pink diamond solitaire engagement ring, the viewing figures of pink diamonds went sky high. The sale of that radiant-cut modified princess and emerald cut stone was responsible for a worldwide surge of inquiries and interest in pink diamonds. The Affleck-Lopez diamond weighed approximately 2.5 carats, and cost $1.5 million. Jennifer Lopez later branded her own J-Lo jewelry line featuring simulated pink faux diamonds. The difficulty with any perfect jewelry investment is finding the perfect stone. But color is back in style, and heirloom collector gemstones are very good investments and very fascinating to look at, so it's just a matter of time before another celebrity pops the question with the famed blue, yellow, pink, purple, or truly rare green diamond. Los Angeles Laker Kobe Bryant's gift of a more than $4 million dollar seven carat purple diamond to his wife Vanessa has likewise helped to skyrocket additional interest in rare colored diamonds. Diamonds are now traded on the Dow. Collector-quality diamonds are wonderful items of great intrinsic and economic value, and they are quite the joy to own and enjoy.
Gemstones and jewelry as an investment works for some people, and not for others. A pure love and respect for gemstones is where some people get their inspiration, collectability and resale value motivate others. One of the true diamond divas of the 20th Century would have to be screen actress Elizabeth Taylor. Her jewelry collection is vast; it is reported Liz' jewelry lockbox containes over 200 carats of the world's top quality diamonds. One stone, the colorless and internally flawless almost 70 carat Taylor-Burton diamond, was given to Elizabeth Taylor in the 60s by Actor Richard Burton. It is a pear-shaped 69.42 carat diamond. The stone has quite a history in that it was originally sold at auction in 1969 with the understanding that it could be named by the buyer. Cartier of New York successfully bid for it and immediately christened it The Cartier. The next day Richard Burton bought the stone for Elizabeth Taylor for an undisclosed sum, renaming it the Taylor-Burton Diamond. It made its debut at a charity ball in Monaco in mid-November, 1969 where Miss Taylor wore it as a pendant. In 1978, Ms. Taylor announced that she was putting it up for sale and planned to, after visiting the country of Africa, use part of the proceeds to build a hospital in Botswana. Just to inspect the diamond, prospective buyers had to pay $2,500 to cover the cost of showing it. In June 1979 it was sold for nearly $3 million dollars, and was last reported to be owned by a Princess in Saudi Arabia. Beauty is in the eye of the beholder, however, with that said, the only thing that has ever been compared to the awesome beauty of a gemstone is the beauty of a woman. That is why the fine gemstones represent love and so many beautiful stones are gifted between people all around the world every single day. When is the last time you bought yourself a beautiful gemstone?
Platinum, like gold, has a long and distinguished history. Its use began in antiquity and it has undergone a resurgence in popularity over the last 200 years. Platinum was held in high esteem during early Egyptian times. Native people in South and Central America worked it as early as 100 B.C. Spanish conquistadors discovered platinum artifacts among the gold they were seeking when they came to the new world. They named the curious metal "platina," or "little silver." They also considered it worthless, and discarded it. Platinum didn't reach Europe until the 18th century, but then it caught on in a big way. King Louis XVI elevated it by terming it "the metal of kings."
It can be found in just a handful of regions of the world. The mining and refining processes are both arduous and time-consuming. For example, in order to extract a single ounce of platinum, about 10 tons of ore need to be mined. After that, the refining process takes a full five months. Platinum in jewelry is actually an alloyed group of six heavy metals, including platinum, palladium, rhodium, ruthenium, iridium and osmium. These other metals are so similar to platinum in weight and chemistry that most were not even distinguished from each other until early in the nineteenth century. Today, it is often alloyed with copper and titanium. It's the only precious metal used in fine jewelry that is 90% to 95% pure, largely hypoallergenic, and tarnish-resistant. Look for platinum jewelry marked 900Pt, 950 Plat, or Plat. One final word about precious metals: Like gold, platinum is durable, sturdy and dependable, making it an ideal setting for your precious diamond jewelry. However, to get a lifetime of enjoyment from your jewelry, be sure to keep it clean and safe. Do not wear platinum jewelry during rough work or when handling harsh chemicals. Store it in a fabric-lined box away from other pieces so it does not get scratched. Finally, check any diamond settings periodically for possible damage to prongs or bezels. If you see a loose prong, or if the setting looks out of line, immediately bring it to a professional for repair.
