StoneAlgo developed our Cut Score to help you understand how sparkly your diamond will look in person
For example, diamonds that receive a GIA Excellent cut grade can range from roughly 6.0 to 10.0 on our Cut Score scale. Those that score lowest are more similar to “Very Good” cut and those that score highest are more perfectly cut.
We recommend looking for a Cut Score of 7.5 or higher.
StoneAlgo developed our Fair Price Estimates to make sure you find a great deal on your big purchase. Our estimate is the price you should expect to pay for a diamond like this one at a top-rated jeweler.
For example, a diamond with a Fair Price of $10,000 that is priced to sell for $12,000 by your jeweler is overpriced by 20% according to our calculation. This estimate is a benchmark and not a guarantee of value.
StoneAlgo developed our Visual Carat metric to help you understand whether your diamond looks larger or smaller than its actual carat weight implies.
For example, a 1 carat diamond could have a Visual Carat of 1.05 (meaning it looks like your average 1.05 carat diamond) or a smaller Visual Carat like 0.95 (meaning it looks like a 0.95 carat diamond when viewed from above).
Length-to-width ratio is calculated by dividing the widest part of the diamond by the narrowest part. A length-to-width ratio of 1.00 would be a perfect circle or square. As the ratio rises above 1 the diamond will begin to look more oval or rectangular. For round diamonds you should shoot for a ratio as close to 1.00 as possible and for fancy shapes it really boils down to a matter of preference.

Not all GIA excellent cut diamonds are created equal, so we built a scoring system that identifies the best and worst cut diamonds.
The best round cut diamonds will exhibit a clearly defined pattern of 8 black arrows extending outward from the center when viewed from above and tend to have a tight, circular spot in the center.
Poorly cut round diamonds will not have a clearly defined pattern of black arrows and the circular spot in the center is usually much larger.
Move the slider to see the difference between a 9.6 cut score and a 6.0 cut score diamond. Both diamonds are GIA excellent cut with excellent polish and symmetry. We typically recommend diamonds with cut scores of 7.5 or higher.
We've created the Visual Carat weight metric to describe how large a diamond actually appears when viewed from above. The visual carat is calculated by measuring a diamond’s surface area and comparing this measurement to the expected surface area for different carat sizes of the same diamond shape.
What is not always made clear is that carat (the most common measure for 'size' when it comes to diamonds) is not a measure of surface area but rather a measure of weight.
While it may seem like we are recommending that you find the lowest depth percentage diamonds, this is definitely not the case. A diamond’s dimensions need to be balanced in order for the stone to display optimal light performance. For round diamonds we calculate this using our cut score and for fancy shapes there are general rules of thumb that can be used. If a diamond is too shallow, the diamond won’t return light properly and we’d recommend against buying the diamond even if it appears much larger than its actual carat size.
