Buying slightly below the “talking points” is one of the shrewdest and most valuable suggestions for saving money buying diamonds. Shopping for diamonds that weigh just under half-carat and full-carat weights.

For example, instead of a 1-carat (100-point) diamond you'd buy a .90-carat diamond. Instead of a half-carat, you’d buy a .49-carat stone. It’s as simple as that. That's a great way to save a lot of money.

Because the price of a diamond jumps dramatically when it reaches a true half-carat or full carat, the advantage of buying “below” is also pretty dramatic! For example: The diameter of a 1-carat diamond is 6.5 millimeters. The diameter of a .90-carat stone is 6.3 mm. The difference is the thickness of a piece of ordinary paper! Looking at the stones side-by-side you’d have a hard time telling the difference.

THE SAVINGS:

.50ct SI1-I    $1,596
.49ct SI1-I    $1,303    You save $293!

1.00ct SI1-I  $6,384
.90ct SI1-I    $5,147   You save $1,237!

1.50ct SI1-I  $11,172
1.49ct SI1-I  $9,512   You save $1,660!

2.00ct SI1-I  $17,024
1.90ct SI1-I  $14,151  You save $2,873!

You’ll notice that buying shy sometimes means a difference of 1 point and sometimes a difference of 10 points. And you’re thinking, “Why don’t I buy the .99-carat stone instead of the .90 carat stone? Won’t I still get the same price break and a slightly bigger stone?”

Yes, but the problem is finding that 99-pointer. Diamond cutters, who are well aware that the full one-carat stone is worth quite a bit more than the 99-pointer, will cheat on the proportions a bit to get the stone up to the full carat. So don’t be obsessed with trying to get closer than 10 points on full-carated stones, but you will find .90s and 1.90s, etc. With half-carat and in-between sizes you will be able to get within 1 point, and find .49s, .69s, 1.49s and so forth. Diamond cutters, who are well aware that the full one-carat stone is worth quite a bit more than the 99-pointer, will cheat on the proportions a bit to get the stone up to the full carat. See article “True Weight” .

The one potential problem with buying shy is a psychological one. What sort of person is your True Love? If she’s going to be upset that you didn’t get the full carat, and will forever think of you as a cheapskate, then it may be worth the extra money.

Your fiancée may never ask how big her 90-point diamond is, but if she does, you might say, “About a carat,” and leave it at that. I believe that happiness is a dream that becomes a reality — and if she sees a diamond that is just what she dreamed of, she'll be happy!

Of course, if you’re a practical couple and you decide to shop for the diamond together, you should both read this first and then decide what you’re going to shop for.
