Culet Size None Very Small Small Outside Ranges

* Note: The table of ideal proportions above should be used as a reference only. Do take note that you cannot judge the appearance of a fancy cut diamond solely based on numbers alone. Physical inspection and the use of ASET to analyze optical performance is recommended. Also, the girdle thickness for pear shapes should be thicker near its tips to provide additional mechanical strength.

The best way to buy fancy shaped diamonds is to see them in real life. Check out the 360° videos of more than 1200+ pear cut diamonds at JamesAllen.com and cherry pick the best looking stone.

Length to Width Ratio For Pear Cuts

Like other fancy cuts, pears can come in all kinds of shapes and sizes. Here is a quick reference on how the different length-to-width ratios translate into various visual appearances. Personally, I favor stones with a l/w ratio between 1.40-1.50 as I find chubbier pears to be more appealing than thin and “malnourished” looking ones.

Outlines of Pear Shape Diamonds to Beware Of

I know I am starting to sound like a broken record but I want to re-emphasize that the grading report alone doesn’t contain sufficient information for you to make a purchasing decision. While physical measurements of the stone are given in the grading certificate, it doesn’t tell you exactly how the diamond looks like. This is where an image or a video of the diamond plays a critical role especially if you are buying online.

That said, there are certain kinds of appearances that you want to avoid when buying a pear shaped diamond. With the help of James Allen, I am able to capture images to show you how the pear diamonds with “bad” outlines will look like in real life.

    Hi Paul,

    Thank you so much for creating this blog, it’s been extremely helpful in my diamond search.

    I would love to get your opinion on the following diamond. Do you think that I can do better for the price point or be able to find something visually similar for cheaper?

    Sorry to double post, but I figured that I’d add the GIA report as well.

    It’s a decently cut pear diamond. However, I think you can do better. Try search James Allen as their video quality is way more consistent.
