Why Choose a 3 Carat Engagement Ring?

The 3ct diamond vintage engagement rings is a popular choice for those with a cultivated taste for fine jewelry. One of the strongest advantages of the 3.00ct – 3.99ct range is its size. A three-carat diamond is large enough to be dominant and bold, but not too big to be overly flashy or get in the way. Since the supply of quality 3 carat diamonds is very limited and there aren’t many boutiques that collect them, customers tend to gravitate towards the few collectors that have them in their collection.

Please note that we have not listed all of our 3 carat rings on our website. If you want to see more rings, please inform us of the specific size or color diamond that you want.

  • A D color, IF clarity and 3.00 carat round diamond should cost approx $240,000.
  • An E, F or G color, VS2 clarity and 3.00 carat round diamond should cost approx $65,000 – $90,000

How to Bring Down the Cost of Your 3 Carat Diamond

There are many situations where two very similar diamond will have very different prices. Here are some of the big factors that could change the price of a diamond:

  • The color. The whiter the diamond the more it is worth. The color scale ranges along a graduation from D to Z. D color = colorless, K color = slight tint of yellow, and Z color = very yellow.
  • The carat. The larger the diamond (or more correctly the weight), the better.
  • The clarity. The fewer inclusions within the 3 carat diamond, the more that it will be worth.
  • The caliber of the diamond cut. A more perfect cuts demand a higher premium.
  • The presence of strong fluorescence will lower the premium by a lot.
  • The type of diamond cut. The round cut usually costs more than the other cuts. For example: Round 3.00 carat, J color and VS2 clarity = $37,500. Cushion 3.00 carat, J color and VS2 clarity = $28,500.
  • Face-up. Some diamonds have a more white appearance in spite of their certified color and will fetch a slight premium.

If you want a 3 carat diamond, but cannot afford the asking price, speak with your jeweler. Discover which aspects of the diamond you want and what you don’t mind compromising on. It could be that you have no problem having a diamond with strong fluorescence which can bring your price down considerably.

What are the Dimensions of a 3-Carat Diamond?

3 Carat Asscher Cut Diamond Dimensions

The dimensions will fluctuate vastly depending on the quality of the diamond-cut and depending on the type of cut. Assuming that the cut quality is very high, we have compiled a list of the measurements of 3-carat diamonds.

  • Round Cut Diamond: 9.50mm x 9.50mm x 5.70mm
  • Asscher Cut Diamond: 7.8mm x 7.8mm x 5.3mm
  • Emerald Cut Diamond: 10mm x 7mm x 4.7mm
  • Square Cushion Cut Diamond*: 8.38mm x 8.38mm x 5.50mm
  • Princess Cut Diamond: 8.05mm x 8.05mm x 5.80mm

*Because Cushion cuts vary in size we could only give the approximate dimensions of a very square cushion cut. Most cushion cuts are rectangular and would, therefore, have very different dimensions.

How Will a 3 Carat Diamond Ring Look on My Finger?

The picture below shows how large a 3 carat ring might look on your hand. The model’s finger shown is a size 5.5 which is slightly smaller than the average finger.

The left picture shows a 3ct diamond ring with a halo of diamonds surrounding it. The picture on the right shows a solitaire 3 ct diamond ring with diamonds along the shoulders. The larger illusion that is shown due to the halo of diamonds is rather compelling.

Shoulder design and filigree can also make your ring appear larger, but it is not usually as effective as the diamond halo design.

It is important to remember that the 3-carat diamond will already look impressive and note-worthy and will not likely need a halo as reinforcement.
