What Is the Price of 1 Carat Diamond?

There is no specific price for a 1-carat diamond as prices of diamonds fluctuate depending on many factors. One can only give an estimate of how much these precious stones cost. Therefore, a 1-carat diamond in Singapore can cost anything from S$1,000 to S$12,500.


Some factors influencing the price of a 1-carat diamond ring include global market trends and demand. A diamond, like any other commodity, will cost more when the demand for it is higher. Conversely, less demand will translate to a dip in its price.


The origin of a diamond also exerts considerable influence on its price. Lab diamonds can be a whopping 75% cheaper than natural diamonds. Availability plays a crucial role in the relevance of this factor to diamond price.

The price value of a diamond depends on its cut, clarity, color, and weight (carat). Qualities have the greatest bearing on the price of a 1-carat diamond. Of these, cut grade influences diamond price the most.


However, all the qualities work together to determine a 1-carat diamond price. A round cut, 1-carat diamond that is colorless and internally flawless will cost north of the S$12,500 mark. In the same vein, an Asscher cut 1-carat diamond that is imperfect and yellow will cost less.


In a nutshell, you may have two 1-carat diamonds whose prices differ considerably. It is a cumulative effect of all these factors. Nevertheless, you have a bargaining strength for a 1-carat diamond in Singapore with S$12,500.

Is 1 Carat a Good Diamond Size?

First, correcting a common misconception about a diamond carat is necessary. The carat is a measure of a diamond’s weight and not the size, as some people erroneously believe. The size of a diamond depends more on the cut and the shape than its carat.


Therefore, a 1 ct diamond will have different sizes depending on how the diamond is cut. The table below gives the different 1-carat diamond sizes according to their shape:



Size (mm)


6.5 x 6.5


8.0 x 5.2


10 x 5


6.5 x 5.5


5.5 x 5.5


5.3 x 5.3


6.6 x 6.6

According to this 1-carat diamond size chart, a marquise cut diamond will appear bigger than one in a round cut. Asscher cuts will look the smallest despite all of them weighing 1 carat.


In terms of weight, 1 carat is equivalent to 200 milligrams or 0.2 grams. This dimension makes it a popular choice among jewelers. Its convenience in size and price makes it easier to sell than other diamond weights.


1 carat is a good deal if you want to buy a diamond. You will get the full value of a diamond in this weight without breaking the bank.

Is 1 Carat Diamond Good for an Engagement Ring?

Sure! A 1-carat diamond ring is good for popping the question if the qualities of the diamond are right. It balances size, budget, and the enthralling feeling of romantic thoughtfulness. An engagement ring set in 1-carat diamond is enough to capture your partner’s heart.


While the weight of the diamond matters, it is not the most important factor when choosing an engagement ring. Your partner’s style and ability exert more influence on your choice of an engagement ring. Therefore, before you buy a diamond ring for your engagement, consider the following:


Your Partner’s Lifestyle


It would be best to consider how active your partner is before purchasing a diamond ring for your engagement. Some lifestyles are more demanding, and a big, weighty ring can get in the way. Therefore, a 1-carat engagement ring is a good fit if your partner is the active type.


On the other hand, some people are not so active and may prefer something bold and eye-catching. If your partner falls in this category, you should look above the 1-carat mark.


Your Budget

Don’t go broke over an engagement ring. A 1-carat diamond ring is ideal if you have to consider your budget while purchasing a diamond ring.


Considering these factors and the qualities of a 1-carat diamond, it is good for an engagement ring. You can win the heart of anyone with an engagement ring set with an excellent 1-carat diamond.
