What are Pear-cut Diamonds?

The shape of a pear-cut diamond is developed by brilliantly combining the facets, brilliance, and fire of both round and marquise-shaped diamonds. Since they have a big spread, such as an oval or marquise-cut diamond, they are larger than a cushion-cut diamond.

The most important points to look for in a Pear-cut Diamond?

  • We recommend that all diamonds be graded by the GIA (the Gemological Institute of America)—the best diamond certification lab in the world.
  • The carat weight depends on your budget. Anything above 1 carat is a good choice.
  • In terms of clarity, SI2 or Slightly Included 2 is fine for under 1 carat. For above 1ct., go for SI1 or above at a minimum.
  • In terms of color, G (near colorless) or above is great. But if you have budget constraints, anything above J color is fine. Also, go for up to medium blue fluorescence in G-J color diamonds, though we recommend avoiding it in D-F color.
  • A cut depth of 55-65% is excellent, while a 52-63% table is preferred. See the cut chart below carefully for more details.
  • Regarding the length-to-width ratio, a ratio of 1.38-1.60 is good, depending on how elongated the pear-cut diamond appears.

The 4 Scenarios While Deciding Which C to Prioritize

Over the last decade, we have seen these four scenarios shoppers fall into as they prioritize the 4Cs and determine which diamond to buy.

Scenario 1: Shoppers go for the highest quality diamond possible within a carat range; we call these “investment-grade diamonds” because they are rare. In this range, shoppers often opt for D-E color diamonds, flawless VVS clarity, and excellent cuts with no fluorescence. Here is an example of what we consider an investment-grade diamond.

Scenario 2: This is our favorite scenario because buyers in this category often take a balanced approach, meaning they do not overly compromise on one C to maximize another. Diamonds in this category still fall within the investment-grade range. The best options under this category are FL-VS2 or even eye-clean SI1 clarity, F-H color, and excellent to very good cut diamonds with ideal proportions and no to medium blue fluorescence.

Scenario 3: Here, shoppers often do not mind compromising on the other 3Cs to get a bigger diamond. However, they still want the stone to be eye clean with optimal brilliance. Hence, they would go for a 2 carat, SI1 clarity, I/J color diamond with a good to very good cut instead of a 1.5 carat, G color, VS2, and ideal cut diamond.

Scenario 4: The shopper often knows that to get a large stone within their budget, they have to compromise on one C to maximize the other 3Cs. In this scenario, we recommend that you compromise on color and maximize carat weight, clarity, and cut. Here is an example that would fit within this category.

Let us get into details about Cut

We believe it is crucial to explain how to assess the cut of pear-shaped diamonds: It is essential because the GIA does not assign a cut grade to them, and only polish and symmetry are not enough to assess their cut. Depth, Table, and Length-to-Width ratios are the most crucial factors when analyzing a pear-cut diamond cut. The thickness of the girdle also bears importance.

Let us now dig into the clarity issue of a pear-cut diamond

The problem of clarity is the same in all diamonds. Since they are formed naturally due to high pressure, their inclusions can be visible in SI or below clarity grades, affecting their brilliance and fire.

So, what should you look out for in terms of diamond clarity? We suggest that you focus on two factors:

First, determine what you can afford and, based on that, what clarity is appropriate. It is not important to go for the highest clarity grade (flawless) since VVS/VS1 are great for investment-grade diamonds. Given that inclusions are natural birthmarks of a diamond, sometimes dealers prefer a VVS grade over the flawless or internally flawless categories because it is one way to distinguish a natural diamond from a synthetic one. It is almost impossible to make such inclusions in lab-made diamonds. If you are on a budget, an SI2 or above clarity grade is fine if the diamond is eye-clean to the naked eye. In this case, getting a diamond with no inclusions on the table is crucial; make sure they are not heavy black crystals. We generally prefer diamonds with a clear table and slight inclusions spread out.

Second, balance the clarity issue with the other 3Cs of the diamond, such as carat weight, color, and cut. For example, it would be wise to get a D-colored diamond—smaller and lower in clarity than one with a better balance of the other Cs—and not compromise the cut. Sometimes, a 0.7ct diamond will look as big as a 1ct, given that the latter is cut shallow to save more weight, thereby compromising its cut quality.

What about the color of a pear-cut diamond?

Like clarity, color is the same in all shapes of diamonds. In terms of importance, it comes second after the cut. But unlike clarity, it affects the overall appearance, which affects one specific spot.

In summary, you should focus on two essential points:

First, decide what you can afford. If it is affordable, go for the highest color grade—D to F colors are considered colorless with no fluorescence. However, G-J colors are considered near colorless and could be good options for people on a budget. Here, our optimal color ranges are G/H or, at most, I color. Medium blue fluorescence is a good ally in G/J color diamonds. Because fluorescence is blue, which complements yellow, it usually makes slightly tinted diamonds appear whiter.

Second, balance the color with the other 3Cs—clarity, carat weight, and cut. While it is an important C, one should not compromise heavily on clarity, carat weight, and, most definitely, not on cut to get a better color diamond.

What about the issue of fluorescence?

The presence of fluorescence affects the price of a diamond, though it can be an ally for people with budget constraints. While it does not affect the brilliance of a diamond in most cases, we recommend avoiding it in D-F color diamonds. The boundary line is G color, where it is neutral, and in H and above color diamonds, up to medium blue fluorescence is often a plus, as it can make the diamond look whiter.

Remember to ask your dealer if the diamond has BGM.

This is a technical term in the industry, and most consumers are unaware of it. It is also not specified in a GIA report, so you will not know. BGM stands for Brown, Green, and Milky. These are shades that some diamonds, regardless of their clarity or color, would have and can affect their brilliance and fire. Ask your dealer to inspect the stone for you and ensure that it does not have any BGM. Most dealers care about their clients and ensure that they get a good stone.

It is also good to have a strong return policy if shopping for a diamond online. In our experience, you must look for the following options when buying a diamond:

  1. Is it a reliable brand/reputable company?
  2. Do they offer a lifetime service plan?
  3. Do they offer fair lifetime upgrade options?
  4. Do they accept returns for a full refund?

Key Takeaways:

Ensure that you have considered seven factors when purchasing a diamond: shape, carat weight, cut, color, clarity, certification, and fluorescence. These are the main factors that affect the price of a diamond. Also, make sure you balance the 4Cs and do not compromise on 3Cs over one particular C. Finally, go for a GIA-graded diamond. They are the most consistent in terms of grading in the industry. The AGSL (American Gem Society Laboratories) is the second lab we recommend if you fail to find a GIA-graded diamond in a specific range.
