Guess where most of the diamonds weight is, yep around the girdle.
Cutters know how to ‘swindle’ proportion sets to maximize weight at the expense of beauty. They choose to retain the weight of a diamond while invariably sacrificing its optical performance. The result is that you pay more for a diamond that looks smaller and underperforms.
Below is a chart that shows that when girdle thickness increases, weight increases but performance remains the same. You’ll pay a lot more for the diamond on the far right and it won’t necessarily perform better.
In this example below, the illustration on the left results in a heavier diamond with less performance. Yes, you’re paying more for less!
To help put the sensitivity of a diamond’s weight into perspective for you, a dollar bill weighs about 5.0 carats. Small adjustments to a diamonds cutting can yield a big impact to the overall weight and final price to you, the consumer.
