It’s a challenge, but not impossible, to find a matching pair of colorless diamonds. Finding matching fancy colored diamonds, however, is a different matter. So, when a matching pair becomes available, the best advice we at Paragon International Wealth Management can give is this: Expect to pay more, but you can’t get a better investment.

    No diamonds, colorless or colored, are truly identical, of course, any more than you’ll find identical snowflakes. You can match them, though. That takes looking for stones that are close in size, color, clarity and, most importantly, cut quality and grading. The idea is to make sure, when they’re examined side by side, that they look similar visually. That means comparing their proportions and the size of each diamond. Professionals will even evaluate how the light bounces off it.

    Matching fancy colored diamonds, however, is a different matter because they’re so rare to begin with. The ratio of colored to colorless diamonds is one colored diamond to every 10,000 diamonds. Compounding that rarity is the vast number of colors of fancy diamonds – 250, actually, given the variations in colors and their intensities. Some have pure colors, like fancy yellow diamonds. But, others, like pink diamonds, which are among the rarest and most valuable, can range from faint and very light to fancy deep and fancy vivid.

    So, what does all this imply for diamonds, and more specifically for colored diamonds, as an investment?

    There’s an investment technique that we at Paragon International Wealth Management, along with other diamond industry experts, use when we come upon “matching” pairs of diamonds. It’s based on the fact that a matching pair can be certified together. That translates into a higher valuation and, in turn, a higher resale value on the original investment.

    Their rarity and price explains why matching pairs command such interest among collectors, investors, and dealers. Richard Eiseman, who heads the upscale Eiseman Jewels in Dallas, Texas, owns a pair of matching blue diamond earrings, one flawless, one VS clarity.

    They were valued at $2.2 million in 2014, and would be worth a lot more than that now, if he wanted to put them to auction. But, the rarity of matching pairs makes them special – and hard to part with. As Eiseman told Patron Magazine, “Once you have an identical pair you’re not sure you want to let go of them because you can’t replace them.”

    A collection of rare diamonds was showcased this year at the Los Angeles County Natural History Museum. Among the highlighted pieces was the Victorian Orchid Vivid Purple Diamond, an exceedingly rare stone because of its unusual color. Given its rarity, it’s fitting that the diamond is fashioned in a ring, its setting complemented by a matching pair of kite shaped diamonds.
