FAQ

To get the most out of Diamond Database take a few moments to familiarize yourself with how it works and how to use it.

This website is all about diamond sizes. If used correctly, it will show you the actual size of a diamond on the actual-sized ring and finger. It will also tell you if a diamond is cut properly and explain in detail all the terminology and what to look for when buying.

The most important features:

• Actual size simulator
• Face-up size evaluation
• Make your own diamond size chart
• Buying guides

How To Start?

It couldn't be easier. On top of every page there is a diamond input form. Enter the weight, choose the shape, and press Go. This will land you on a single diamond page. If you want to check a particular diamond and have the measurements, put them in also.

When buying a diamond, you can use this site to verify the size and cut, and get an idea of how it would look on your finger.

To compare 2 diamonds side-by-side press Compare button that is usually located somewhere near the top of the page. Put in the data and off you go. Compare form is also always available near the bottom of any page.

Actual size

In order to view a diamond, ring and finger in actual size, the application must know your device screen size. Unfortunately, it’s not possible to recognize the screen size automatically, so it has to be set manually.

You can see and change to what screen size the "actual size" is adjusted to in two places:

• near the diamond actual size image at the top or
• under the finger image

If screen size is not set to your device screen size (diagonal in inches), then actual size will not be correct. After it's set, the images will automatically recalibrate to actual size. You only have to set this once, the site will remember your setting, so make sure the actual size is adjusted to your screen size.

Face-up Size Evaluation

Not only will this site show you the actual face-up size of a diamond, but it will also evaluate it. If a diamond is not cut properly, its face-up size will be either too small (usually) or too big. In both cases it won't be a pretty diamond.

You can learn more about face-up size evaluation here.

Make Your Own Diamond Size Chart

Take the guesswork out of diamond sizing and make your own custom diamond size chart. You can compare all the shapes you're interested in at all carat sizes (0.05-10ct), all on one page.

It's simple: select the shapes, choose the weight (ct) range, and hit the "Make my Chart" button. You can then print the created chart if you want to cut out the shapes and try them on your own finger. It's the easiest way to see what size and shape looks best on you.

Or you can download the chart to your device as an image. If you want, you can share it on your website, blog, social media... You're free to do so.
