Nope! Diamonds may seem rare because the distribution of the number of diamonds released to the market is highly regulated. If all the diamonds in the world were to be released, there would be enough to give each man, woman and child in the United States a cup full of them.

This might have been true in the past, but now women, and men, are better educated about the qualities of diamonds thanks to the many books and other gem educational websites such as ours.

Actually, there are other gemstones out there that are more expensive than diamonds. A top-quality ruby for example, could be worth over $32,000 per carat.

Size is only one variable that determines a diamond’s value. A small, high-clarity, high-color diamond can cost more than a large, low-clarity, low-color diamond.

Actually, when a diamond is cut (shaped and polished), it is grounded down. The only thing that comes off the diamond is dust.

All diamonds are difficult to cut. Very large diamonds take more time and effort than smaller ones, but the shape of the diamond doesn’t make it any more or less difficult.

This is only true if the diamond will be resold. Since most people only buy diamonds to be worn, used and passed on, diamonds don’t make good investments. With proper education and training, diamonds could be good investment items, but for the average person, buying a diamond for personal enjoyment, fulfillment and prestige is perfectly fine.

Diamonds may not be a good investment to the average person, but they aren’t bad either. Just like any investing, if a diamond is purchased at the right price, it will most likely retain its value. Since the diamond crash of 1979, when a D flawless diamond fell from $75,000 to under $15,000, the price of diamonds has been increasing.

Many people think that “what I can’t see can’t hurt me.” This can lead to disaster. Jewelers spend a lot of money on spotlights to make their merchandise sparkle. Unless you plan to do the same, you’d better read up on the 4 C’s or you might end up buying a diamond that looks great in a jewelry store, but terrible everywhere else.

This is absolutely not true. The emerald cut is the least expensive of all the shapes. Because the emerald shape is closest to the natural shape of diamonds, less work needs to be done on it with less waste during the cutting process.

A perfect diamond would simply be a diamond free of inclusions and blemishes when viewed under a 10x loupe (flawless), with no trace of color (D color), and perfectly proportioned. Even though they’re rare, they do exist. One such diamond came up in auction in 2003. Read the article An Evening at Sotheby's.

Any good jeweler can tell the difference immediately. A CZ has a plastic look to it. CZ has a light-blue cast throughout the entire stone. Another way of telling the difference is by weight. A CZ will weight about 65% more than an actual diamond.

Some are, some aren’t. It all depends on the quality. It’s possible to get a 1 carat diamond for about $300 if the quality is low.

This is entirely based on opinion and the popular song “Diamonds are a Girl’s Best Friend” from the hit Broadway show and film, “Gentlemen Prefer Blondes.” Some women love diamonds, others don’t.

If you're talking about Old Mine Cuts, then yes, they are not as brilliant, but they have more fire (color play) than modern round brilliants. Modern cushion cut diamonds rival modern round brilliants in brightness.

Diamond clarity always matters, whether a diamond is irradiated or not. This myth may have originated from some jewelers assuming irradiated diamonds were "less of a diamond", down at the level of semi-precious stones like the heat-treated stone blue topaz. Diamonds, even irradiated ones, have significant value compared to most gemstones.
