ON BUYING A DIAMOND
If a diamond should be other than the above explanation, it will be either shallow (or fish eye), which would give the diamond a hollow appearance. If it should be too thick, the diamond would appear blackish.
The next consideration is color. Diamonds sold for commercial use are of the fine Blue White color down to shades of yellow or brown. A slight shade in color has an effect on the value of a dia­mond. Here again, having confidence in your first class jeweler, plays an important part. It is difficult to "carry" color in your eye for comparative purposes. It is equally difficult, if not impossible, to explain to the layman what really constitutes a Blue White Dia­mond. For commercial purposes, I would say that a blue white diamond should not have any trace of color.
The next consideration is perfection. Here is another reason why your first class jeweler plays an important part. A diamond, to be perfect, must be free from the minutest imperfection, such as a pin point or a very slight line, and the perfect diamond is determined with the aid of a ten-power loupe. It would be useless to say that a layman, in purchasing a diamond, could determine the minutest imperfection even with the aid of a ten-power loupe.
In other words, says Mr. Kafka, (1) figure out whether you want quality or quantity; (2) get a reliable jeweler; (3) don't delude yourself that you can determine quality through a loupe unless you are trained to do so; and 4, 5, 6— and all the way to 100) get a reliable jeweler!
The latter reiteration may seem to be overemphasizing a piece of advice, but it is all-important. The average dia­mond purchaser knows nothing whatever about diamond values. He—or she—knows nothing e,ven about sizes. Dur­ing a recent nation-wide survey several thousand men and women, including college students as well as elderly per­sons, were asked to estimate the carat size of certain imita­tion diamonds submitted to them. Only about half of them came even reasonably close to the correct size. Taking a one-carat stone, 67 per cent couldn't decide what carat it was,
