Question: How Can I Find the Best 1 Carat Emerald Cut Diamond?

Most online jewelers allow you to search for all of the parameters I list below in this article. I have created a direct link to emerald diamond search pages at James Allen, Brian Gavin Diamonds, Blue Nile, and Leibish at the end of this article for your convenience.

 

This year has seen an increase in the demand for emerald cut diamonds. As such I decided to write a little bit about how to go about finding the best emerald cut diamond.

Definition of emerald cut diamond:

Emerald Cut diamonds are oblong step cut diamonds with a large, open table. The corners are truncated to avoid points of weakness.

Image: Brian Gavin Diamonds

Categorized as a fancy cut, the emerald cut was originally developed for the cutting of emeralds, and came into vogue as a popular fancy cut diamonds during the Art Deco period.

This shape, which is usually known as emerald cut diamond, step cut, or trap-cut accentuates a diamond’s clarity. The large table makes it easy to see right into the diamond.

Like other fancy shaped diamonds, emerald cut diamonds can come in a variety of length to width ratios. The classic outline of emerald cut diamonds usually have a ratio of 1.00:1.50 though ratios of up to 1.00:1.75 are also found to be pleasing to the eye. If the diamond has a 1.00:1.00 ratio it is usually called an Asscher shape as I outline in this article here:

What is the difference between Asscher and Emerald Cut Diamonds?

Ideal proportion is not as clearly defined for emerald cut diamonds as it has been for round cut diamonds. Emerald Cut diamonds, as is the case with many other types of fancy cut diamonds, will be cut to a wide variety of shapes, each with a slightly differing proportion. These variations, particularly in the pavilion, makes the science of light performance extremely complex for fancy shapes. As a result you will not find any cut grades noted on gemological reports issued for fancy cuts. This means you will rely more on the jeweler to help you with choosing your fancy cut stone. For this reason it is quite important to choose the jeweler carefully before getting too caught up in the details of diamond geometry.

There are some guidelines to follow when choosing an emerald cut diamond which can help but the truth is that without extensive diamond experience this will only get you so far. A trained gemologist is much more likely be able to help you find what you are looking for as they will know a lot more about the subtle differences between different emerald cut diamonds.

My choice would be to ask Brian Gavin Diamonds for advice when choosing an emerald cut diamond if your choice is to buy your diamond from an online jewelry retailer.

Emerald Cut Diamond Buying Tips

Following are a few points to help get you started on your search

Best options for Emerald Cut Diamonds
Best options for Emerald Cut Diamonds

Clarity

The shape of Emerald cut diamonds, with its large open table, makes it well suited to show off higher clarity grades.

Clarity grades for emerald cut diamonds are shown on the diamond lab grading report (unlike cut grade, for which, as far as fancy cut diamonds go, there is no established science).

Since the clarity of emerald cut diamonds or other step cut diamonds is going to be much more obvious it’s advisable to select from the following range:

  • VS2
  • VS1
  • VVS2
  • VVS1
  • IF

Color

A slightly warmer color range is often considered to be as nice or even nicer than cooler color grades. This is due, in part, to the large open table on emerald cut diamonds. Another reason is that the light play is considerably different in an emerald cut diamond when compared to a round brilliant. The choice of color grade is therefore up to your personal preference.

Warmer colors are found among the following colors on the GIA color scale:

  • L
  • K
  • J
  • I
  • H
  • G

Cooler tones will be found among the color grades that are near colorless on the GIA color scale:

  • F
  • E
  • D

The following video is of an emerald diamond that has a slightly warmer color (the L color on the GIA scale) and you can see that it looks gorgeous. Also note how the large table allows the viewer to peer into the diamond and appreciate its clarity.

 

Cut Grade

While the actual cut grade for fancy cut diamonds like the emerald cut is not something that has been firmly established in the diamond industry* there are certain ratios which seem to work better than others and which would place a diamond in a better cut grade if this were something that laboratories were prepared to include on the diamond grading report. Some of the grades listed below are subjective and it’s an area where opinions do vary even between specialists.

*Even round brilliant cuts, which have been the subject of a great deal of study, can still have variability even among diamonds that have all received a top grade. Finding a good jeweler to deal with is always more important than just looking at a grading report. Check out the list of recommended diamond jewelers on our home page.

Having said that, there are some numbers which can serve as a rough guide which I list here:

The Best Place To Buy Oval Diamonds

The result of hundreds of hours of research and comparing is finally in and I can share with you what I deem to be the best places to buy oval diamonds. This is mainly if you are interested in making your purchase online rather than in person. Although I do have a recommendation elsewhere on this website as to the where to look for the best deals on oval diamonds if you want to go to a place in person, this article’s aim is to help you if you are interested in buying your diamond jewelry via a website.

Today’s article will be showcasing a jeweler that provides a very useful service when it comes to buying oval shape diamonds. As explained in more detail below oval shape diamonds come in many different ratios. Some ratios are better than others. The jeweler I am showcasing in this article sorts through the higher quality diamonds held by manufacturers and only allows the ones that meet his strict criteria for optimum ratios to be listed on his website. This jeweler is none other than Brian Gavin.

Brian Gavin Diamonds

This is the direct link to the Oval diamonds that are listed on BrianGavinDiamonds.com right now.

Brian Gavin Diamonds has been chosen to be showcased as one of the best places to buy oval diamonds for a number of reasons. Primarily this online jeweler demonstrates the highest level of care in every aspect of jewelry and diamond production as well as in the area of customer service. Brian Gavin himself is a fifth generation diamond cutter.  This is an advantage which shows in every aspect and is consequently appreciated by the many happy recipients of Brian Gavin jewelry.

The oval diamonds listed on Brian Gavin Diamonds’ website have been selected because they meet the strict criteria set by Brian Gavin.

Diamonds and jewelry within their virtual selection have been chosen because they meet Brian’s strict Select quality standards. These are diamonds that exhibit outstanding cut, color and clarity as demonstrated by their light performance.

These select stones represent the optimum balance between performance and value.

Oval Diamond Buying Tips

There is a range of ratios to choose from when it comes to oval shape diamonds. The optimum ratio is somewhere around 1.5 : 1, though it’s quite unheard of to actually find a diamond that is exactly this ratio. The range most people find pleasing is between 1.3:1 and 1.7:1.

The choice though in the end comes down to personal taste. If you see a shape you like take note of its length to width ratio. Calculating the length to width ratio of a fancy shape diamond such as an oval diamond is very easy. Simply divide the length by the width. These numbers will be found on the diamond’s grading report. Unfortunately the grading reports do not include the calculated ratio. Grading reports will show you three numbers in millimeters. The largest number is the diamond’s length, the smallest number will be the diamond’s depth. This leaves the middle sized number as the diamond’s width.

For example:

Here we have an oval diamond listed on Brian Gavin Diamonds website.

www.briangavindiamonds.com/diamonds/diamond-details/0.750-i-vs1-oval-diamond-gia-s30375

The measurements are shown to be 7.38 x 5.30 x 2.94. These are all in millimeters.

The smallest of these three numbers is 2.94 and this is the diamond’s depth.

The largest is the length, since it is an oval diamond after all, this makes sense.

Divide 7.38 by 5.30 and we get 1.39.

The length to width ratio is therefore shown to be a very acceptable 1.39:1. This is the kind of high quality offerings we can expect to find at Brian Gavin Diamonds.

Oval diamonds exhibit a unique effect called the bow-tie effect. It is a cute little optical effect created by differences in refraction. This occurs at the junction point in the middle of the diamond. The bow-tie effect is somewhat reduced and therefore less obvious in diamonds with the above specified optimum length to width ratios that also have a depth anywhere between 58% to 68%.

Most Beautiful Cushion Cut Diamond (1 carat)

Cushion cut diamonds are the diamond of choice for many savvy diamond buyers.

English: Nearly octahedral diamond crystal in ...

Due to the form of a diamond, cutting the diamond into a round shape results in some loss of mass. There are plenty of advantages to buying a round diamond, such as being able to buy a diamond that is of a lower color grade without noticing the difference. However not everyone wants to go for a lower color grade.

If you want a higher color grade then princess (which is essentially the square cut), asscher (also called emerald cut), or cushion cut would present a very attractive option. Less diamond has to be chipped away to make these shapes as they are much closer to the original shape of the diamond when it is initially mined. The image seen here is what a natural diamond looks like when unearthed. The most frequent process applied is to cut this rough diamond into two. Any final shape that is somewhat square will save more of the diamond from getting cut away. ‘This can often result in a lower cost per carat. The round brilliant shape has the best light performance, but there are a few diamond cutters who manage to make the other shapes also perform extremely well.

Cushion cut diamonds may be sought by people who think that the corners of the princess diamond may be vulnerable to chipping. It is only a very small risk, but some people want to play it safe and therefore choose a cushion cut diamond, or an emerald cut diamond. If you want an emerald/asscher diamond I wrote an article on what to look for in those types of cuts here.

Brian Gavin Select  Cusion Cut Diamond 0.783 E color VS2 clarity
click image to go to this diamond at Brian Gavin Diamonds

This diamond was one of 32 diamonds added to the Brian Gavin inventory today.

After looking over each one’s images and grading report I felt that I should place this one here as our Catch of The Day. 

All of Brian Gavin Diamonds are in a class of their own, as everything coming from Brian Gavin Diamonds just stands out as being so perfect. When looking over all the new inventory I felt like they are all finalists in a beauty contest. However I consider this particular one to be outstanding and not only the top performer, but representing the best value.

I have highlighted the characteristics which make this diamond exceptional, and the ASET image also indicates that this diamond is truly magnificent.

With actual photos of the diamond in high resolution you get to see exactly what the diamond looks like.

Don’t expect to find high resolution photos of diamonds at every jewelry seller’s website. Of the hundreds of thousands of diamonds for sale, only a small percentage get photographed like this. The majority of the time buyers have to make do with stock photos, and one has to read through the diamond certificates to get an idea of how nice the diamonds are.

This 0.783 carat E color VS2 Select Cushion Cut Diamond can be seen in the image above. And the best aspects are its cut, which even though cushion cut diamonds do not get a mention of cut grade on the grading report, the ASET shows how much brilliance can be seen in this diamond, confirming that it is an Ideal cut. Also of note is the color (E, very rare!), and its VS2 clarity which would require 30x magnification to see any inclusions! All in all an ideal diamond for a lovely engagement ring.

Finding The Best 2 Carat Round Brilliant Diamond. Budget=$25000

If you want to spend a larger sum on a larger diamond you’ll want to feel some assurance that it is going to be worth the price you have paid for it. The reasons for spending big will of course vary, however I am going to assume here that a budget of $25,000 is accompanied with a desire for not only a large but an exceedingly beautiful diamond.

Is is possible to spend $25,000 and end up with a dull stone?

To be quite frank it’s not that easy to find a dull diamond at that price as long as you stick to our recommended list of jewelers. They know that it is not worth stocking dull and inferior diamonds. It just creates extra hassle with having to deal with unsatisfied customers.

They haven’t built up their reputations as high quality reliable business by taking shortcuts.

So it is comforting to know that we are only going to be tweaking things a little to make sure we have the best performing diamond, truly deserving of its price tag.

If the budget is $25,000 and the aim is to find a 2 carat diamond, we can make sure to eliminate any under-performers by trying to find diamonds with a grading report (diamond certificate) issued by AGS Laboratories.

Why? Because there is a very useful feature included on a certain type of AGS grading report which the lab has been issuing in the past few years. It is the Platinum Light Performance Diamond Quality Document.

Not the kind of document name you can turn into an easily pronounceable acronym, but nonetheless a very useful document.

I like what AGS says on their website:

<< Begin Quotes >>

There are several patented technologies encompassing the system with enough technobabble to satisfy the nerdiest among us.

However, the IDEAS behind the system are based on good old common sense.

The complex pattern of light and dark in the diamond is really a fun house view of the surrounding world.

<< End Quotes >>

Read the rest here: http://www.agslab.com/light-performance-cut-grade.php

If you’re like most people and don’t feel like studying table percentage values just to choose a diamond don’t feel overwhelmed. As stated above, most 2 carat diamonds with a value of $25,000 are top performers and there won’t be that many to choose from. The easiest way to perform this search is to set your search values to include diamonds over 2 carats, and close to $25,000. You’ll see that most diamond jewelers only have diamonds that are Excellent/Ideal cuts or Very Good cuts. Once you have narrowed down your search to a couple of diamonds, check to see if it is an AGS grading report and have a look at the grading report. Some places even let you select only those diamonds that have an AGS grading report ( James Allen for example). The majority of Brian Gavin Diamonds are graded by AGS.
