Buying a diamond engagement ring is no mean task for the average shopper with limited experience. Besides understanding technical jargon and certification, there are many things to keep in mind when searching for the right diamond.

Since you are reading this article, you probably arrived at the decision of what weight you want the diamond to be – 1.4 carats. But are there tips for shopping for something so specific? What about where to get a great deal for a 1.4 carat diamond ring of your dreams?

In this write up, you will find answers to those questions and insider advice to help you buy a stunning engagement ring. Let’s jump right in!

How Big is a 1.4 Carat Diamond?

First of all, the physical size of a diamond depends on factors such as its shape and the proportions in which it is cut. In general, the size of a 1.4 carat round diamond would be roughly 7.22 mm by 7.22mm if it is cut with ideal proportions.

For some context, the size of a 1.5 carat round diamond would be roughly 7.4mm by 7.4mm and you can see a reference carat size chart below for visualization.

Basically, a 1.40 carat diamond would look almost the same visually as a 1.50. For this reason, 1.4ct diamonds are highly sought after in the market because they are just under the magic mark of 1.5 ct where the price per carat would increase significantly.

What is the Price of a 1.4ct Diamond Engagement Ring?

When it comes to the price of a 1.4 carat diamond ring, there’s no definitive answer as the cost of a diamond depends on many factors like the 4Cs and the shape of the diamond.

Obviously, if a diamond has better material quality and is graded as a D color or internally flawless clarity, you would expect the price to be much higher compared to one with lower grades.

Here’s a price chart that compares diamonds with different qualities. As a ballpark figure, you can expect to pay anywhere between $6,000 – $20,000 for a GIA certified 1.4 carat round diamond. Depending on your budget, you will need to calibrate your expectations of what you can get in the market.

Practical Tips to Buying a Beautiful 1.4 Carat Engagement Ring

When buying a diamond ring, the most important aspect that determines its sparkle and brilliance is cut quality. I want to highlight this because most people wrongly assume that a diamond with better color and clarity will have better light performance.

That’s actually misinformation spread by jewelers and salespeople to make you spend more on a diamond. And for a beginner shopper, it is a common mistake I see people making when they are choosing a diamond.

So, here’s my personal recommendation of the 4Cs when shopping for a diamond that’s based on practical reasons and helping you get better value for your money.

Clarity: VS2 or better (eyeclean is good enough)
Color: G or better (for diamond to face up white)
Cut: Ideal / Excellent (review scope data for light performance)

The rationale for these guidelines is simple. For a large size 1.40 carat size diamond, you would generally be able to get an eyeclean diamond by sticking with a VS2 or better clarity. The fact is, your unaided eye will probably not be able to tell any visual differences when looking at a VS2 or IF clarity diamond in a side by side comparison.

Likewise for color, a G color grade would be sufficient for the diamond to face up white without overpaying for a D color diamond. Instead of paying the premium for a D color grade which your eyes may not appreciate, you can save a lot of money by going down to a G color rating.

At this point, I do want to mention that it is perfectly fine if you want to buy a D/IF diamond for symbolic reasons or if you simply want to have the “best of the best”. Likewise, there’s nothing wrong with buying a K color diamond especially if you like to see a warm tint or use the diamond for a vintage style setting.

The key is to understand what you are buying and being educated in knowing why you are paying a certain amount of money for the purchase.

Lastly, don’t forget that a reliable grading report from GIA or AGS is mandatory when you are buying a 1.4 ct diamond. Make sure you stay away from any other dubious certifications as they over inflate and misrepresent the quality of the diamond.

Where Are the Best Places to Buy a 1.4 carat Diamond Ring?

    I’ve been searching for a 1.4 carat emerald cut diamond on some of the sites you recommended above. In the videos, I can see inclusions and black spots quite noticeably and it doesn’t seem that there are many clean looking VS2 diamonds. I’m worried that they can be seen when people casually look at the engagement ring.

    The guidelines I recommended above are generally for round cuts or other shapes with brilliant cutting styles. For step cuts like emerald and asscher cuts, they have less brilliance to mask inclusions and because of their large flat surfaces, they tend to show inclusions easier. If you are in the market for step cut stones like a 1.4 carat emerald cut diamond, then you may need to increase your clarity to a VS1 or better. But I would say that you should be able to find some nice looking VS2 diamonds easily on James Allen and Blue Nile.
