How Big is a 4 Carat Diamond Ring?

The picture below is a demonstration of how large a four carat ring might look on your hand. Due to the size of the 4 carat diamond, the ring style will not really require a halo of diamonds around the center. A 4 carat round diamond has an approximate width of 10.30mm and will fill the finger nicely.

Assuming that the average finger size is 17mm, a 4 carat diamond will fill 60% of the finger’s width. The ring will take up 70% – 80% of the finger’s width if you add a halo.

This picture is of a 4 carat vintage engagement ring on a finger. Note the elaborate designs along the shoulders.

How much does a 4 Carat Diamond Cost?

The chart shows the market prices for a 4-carat diamond. Due to the rarity of the 4-carat diamond, the actual price may likely be a lot more. As the diamond weight size becomes larger, so does the premium for its rarity.

Please note that the prices below are for a 4.00-carat diamond. (Obviously, a 4.50-carat would cost substantially more.)

Color Range	SI1 Clarity	VS1 Clarity	IF Clarity
K Color	$52,000	$62,100	$80,500
J Color	$64,500	$73,600	$96,000

The above prices illustrate how much a 4-carat diamond costs. In order to compare 4-carat prices against other carat weights, we have created a list to help you contrast costs:

• 1-Carat, J Color, and VS2 Clarity will cost approximately $5,700.
• 2-Carat, J Color, and VS2 Clarity will cost approximately $17,000. To learn more about 2-carat rings, click here.

These prices are approximate for high-quality round-brilliant cut diamonds. A 4 carat emerald cut diamond ring or 4 carat oval diamond ring, for example, would cost less.

Technical 4-Carat Terminology

Like all industries, diamonds have lots of trade terminology that may be lost on the average consumer.

4 Carat Weight vs. 4 Total Carat Weight

It is important to understand jewelry vernacular before making your purchase.

Many jewelers will tally up the diamond weight from all the diamonds in the ring and list the ring with that value. So if, for example, the center diamond is 3.40-carats and the side diamonds and halo diamonds equal 0.66-carats, they will list the diamond ring as a 4.06-carat.

It is very important to pay attention to the details before making your purchase. Carat weight is CW, and Total Carat Weight is TCW.

Please note that at Estate Diamond Jewelry, we don’t believe in listing our rings this way. All the carat weights listed on the rings on our website are based on ONLY the center diamond.

4 Carat vs. 4 Karat

This is one of the most common mistakes that people make when searching for diamond size. These two words sound the same but mean something entirely different.

Carat, as in “four-carat diamond ring”, refers to the weight of the diamond. A 4 carat diamond weighs 800 milligrams. Carat is a direct reference to how heavy the diamond is.

Karat has nothing to do with diamond weight. In fact, it has nothing to do with diamonds at all. Karat refers to the purity of gold. Pure gold is 24-Karats. Gold that isn’t pure, and is mixed with 25% of alloys, will be 18-Karat.

Understanding 4 Carat Vintage Rings

Many of those looking for diamond rings within the 4-7 carat range are looking for antique diamonds and rings. There are usually many reasons for this preference, but the two most popular reasons are the ethical advantage and the superior craftsmanship.

Ethical Advantage: Antique rings and diamonds have the furthest connection to supporting wars and global atrocities. Even with all the current regulations, you can never be certain of the true origin of modern diamonds. Antique rings, however, have already been in circulation for over 100 years.

Additionally, antique diamonds and rings aren’t contributing to the environmental repercussions that occur due to the unregulated and ineffective ecological mining practices.

Craftsmanship: The rings that are produced today aren’t a fraction as good as the rings that were crafted during the Edwardian and Art Deco Eras. Those that are looking for rings of finer quality usually gravitate towards rings that were handcrafted between 1900 – 1945.

Buying a 4 carat diamond ring is a big decision. Here at Estate Diamond Jewelry, we have been curating 4 carat diamond rings for over 35 years. There are several things that you should know before making your decision. Here is our top advice.

• First and foremost, research the sellers. Buying a 4-carat diamond is a big decision. Make sure that your seller has a pristine reputation. Check Google Reviews, Yelp and BBB.
