A 3 carat diamond is an excellent choice for a ring

If you want a diamond ring more special than what most people have, a 3 carat diamond is an excellent choice.

Carat is one of the 4Cs that affects the price of a diamond. Many people think carat is a unit of size, but it is in fact a unit of weight. The word carat comes from the Carob seed, which was used centuries ago to determine the weight of precious stones as the seeds have a uniform weight. When diamonds are weighed, they are given a carat weight commonly rounded off to the second decimal place. One full carat weighs 200 milligrams, or 0.007 ounces.

Another diamond size? 1 carat diamond, 2 carat diamond, 4 carat diamond, 5 carat diamond, 6 carat diamond, 7 carat diamond, 8 carat diamond, 9 carat diamond, 10 carat diamond or go to the Diamond Wholesale Prices

How much does it cost?

That is why just one 3 carat diamond will be worth much more than three 1 carat diamonds. In fact, carat weight does not affect value or size proportionately. A 1 carat Round Brilliant Cut has a diameter of 6.5mm, whereas a 3 carat Round Brilliant Cut is 9.3mm. As for the price per carat, a 3 carat diamond weighing 600 milligrams ranges between $6,050 and $ 84,810 per carat.

What are the wholesale prices of a 3 carat?

If you are interested in buying a diamond that is more special than the diamonds most other people buy, then you’re in the right place.

To calculate the average final wholesale price of a 3 carat diamond, multiply the price per carat of the diamond you want by 3.

The average wholesale price of a 3 carat Certified GIA Diamond would range between $ 18,150 and $ 254,430.

3 carat diamond rings guide

What are the popular 3 carat diamond engagement rings?

A 3 carat diamond engagement ring that is set in a plain and elegant solitaire setting will already look stunning as the size of the stone is larger than usual and a well picked sparkling diamond is a natural beauty on its own. However, 3 carat diamond rings do come in many different styles to fit the personality of every bride-to-be.

The favorite picks for grooms-to-be and their special someone:

  • A solitaire setting with pave diamonds in a thin band

This diamond ring setting keeps the focus on the center 3 carat stone by having it set in a visible “stage”, the prong, while the size of the center diamond is boosted due to the optical illusion of the thinner ring band filled with pave diamonds.

If you want to stand out a bit more, choosing fancy cut diamonds such as a cushion, emerald, pear or oval shape diamonds is a good choice. The shape itself will give some extra uniqueness to the ring’s appearance. In addition, a solitaire diamond engagement ring price with a fancy cut diamond is lower priced than an engagement ring with a round diamond.

  • A 3 stone setting

The popularity for the 3 stone diamond ring setting got a big boost as royalty Prince Harry proposed to Meghan Markle, now the Duchess of Sussex, with a 3 stone setting. The ring setting complements the center stone while giving it more character based on what side stones such as half moon, baguette or pear cut diamonds you choose.

Please note that not all carat sizes are suitable for this ring setting as the side stones can distract the appearance of the center stone and can make it look smaller.

  • A split shank setting

Engagement rings that have a split shank feature a band that parts as it reaches the center setting. These diamond ring settings have a visible gap between the band and the center stone and create the effect of making the 3 carat diamond appear larger and more ornate. Many split shank settings are set with micropavé diamonds to make the whole engagement ring sparkle.

Does jewelry metals for fine jewelry influence the diamond color?

No, the diamond color will always stay the same but yellow gold or white gold can influence the appearance of your diamond color for the naked eye. It is recommended to stay away from yellow gold ring settings if your graded diamond is I color or lower. The yellow gold will make the diamond look only more yellow. However, if you really like yellow gold for your ring creating the setting in two tones is an option. By making the basket of the ring white gold can prevent the diamond from looking more yellow due to the reflections.

Are custom 3 carat diamond rings more expensive?

At the Diamond Registry they are not as we have in-house jewelry designers that do the designing with you, free of charge. You will only be paying for the materials of the ring, so picking a finished style or making your own design is the same – sometimes even cheaper! Because purchasing a diamond ring from a big brand means paying for the design and the name too. So why wouldn’t you go for a more personalized ring that is unique and can’t be purchased anywhere else if its same price or cheaper?

If you decide to personalize a ring of your own, it does not have to be from scratch and can be based on different ring styles that have inspired you. Because all your ideas will become one when you are sitting with one of the in-house designers.
