What is a 2 Carat Diamond?
The biggest and most common mistake that people make when referring to the ‘carat’ of a diamond is thinking that this term refers to the diamond’s table surface area. The term ‘carat’ is used to communicate the weight of a diamond. For a 2 carat ring, the weight of the diamond is 400 milligrams or 0.4 grams. If you are struggling to imagine what this measurement entails then it might help to know that this is equal to the weight of half a raisin.
How Big is a 2 Carat Diamond?
As has been mentioned, a 2 ct diamond ring does not have any set size. As the carat number refers to weight, the diamond cuts will influence its actual table surface area or size. A perfectly round 2 ct diamond should have a diameter of precisely 8.10mm. If, for example, your diamond is cut in the marquise shape then its table surface area measurements will be 13.08mm x 6.54mm and in the case of an oval diamond it will be 10.23 mm × 6.82mm.
The shape that the 2 carat ring is cut in will significantly influence the perceived size of the diamond. Albeit they might both have a 2 carat weight, an oval cut will most likely appear to be larger than a perfectly round cut due to its elongated form.
How Much is a 2 Carat Diamond?
The selling price of a 2 ct diamond varies greatly depending on a number of factors. On the more affordable end of the spectrum, a 2 ct diamond would cost a minimum of $14 000. This would be the standard yet classic round brilliant cut. To demonstrate the vast range of diamonds of the same weight and shape, a more expensive, and arguably better cut, round brilliant diamond would be $20 800. At the highest end of the spectrum, a 2 ct diamond will cost around $26 250.
How to Choose a 2 Carat Diamond
The best advice you can receive when looking to purchase the diamond of your dreams is to focus on the famous “four Cs”. These are carat weight as well as cut, color, and clarity grade. The color grade of a 2 carat ring ranges from absolutely clear (D) to a light yellow (Z). If you are looking to compromise slightly on the color in order to minimise costs, we would recommend sticking between the color grades of K and L.
The cut grade of a diamond influences its brilliance and sparkle. The Gemological Institute of America (GIA) bases the cut grade of a diamond, which can range from poor to excellent, on seven factors: fire, weight ratio, brightness, scintillation, durability, symmetry, and polish.
It is particularly important to inspect the clarity grade of a diamond when purchasing a 2 carat ring. When compared to a 1 carat diamond of the same shape, a 2 ct diamond will have a larger top flat surface, otherwise known as the ‘table,’ and therefore the presence or absence of inclusions will be more noticeable.
Where to Buy a 2 Carat Diamond Ring
Considering the financial implications of purchasing a 2 carat ring, it is certainly worth shopping around before making any final decisions. 2 ct diamond rings are certainly not stocked in the same abundance as 1 carat rings and so you might encounter a slightly smaller selection. The most important thing is that you are purchasing your diamond ring from a reputable and accredited jeweller.
Is a 2 Carat Diamond Considered Big?
A 2 carat ring is certainly considered to be big. After all, the global standard for diamond rings is 1 carat – if that. Therefore, a 2 carat is a very impressive doubling in weight of what most people already consider to be a sizeable diamond.
What is the Difference Between a 1 and 2 Carat Diamond?
As has been mentioned, the carat of a diamond refers to its weight, not its size. A 1 carat diamond weighs 200 milligrams or 0.2 grams while 2 ct diamonds weigh 400 milligrams or 0.4 grams. The cut, color, and clarity grade will influence the price of these diamonds but their difference in weight will always be the greatest distinguishing factor.
Why are 2 Carat Diamonds More Expensive than 1 Carat Diamonds?
The price of a diamond increases exponentially in relation to the carat weight of the stone. The more a diamond weighs, or the higher the weight category, the greater the cost per carat will become. This phenomenon can primarily be attributed to the fact that heavier diamonds are rarer and therefore, more valuable. Since a 2 ct diamond ring is sure to impress any individual, people are willing to pay the premium price.
Should I Get a 1 Carat or 2 Carat Diamond?
Choosing between a 1 and 2 ct diamond is a highly subjective and personal decision. A heavier diamond allows for a greater display of its dazzling brilliance and elegant splendour.
A 1 ct diamond ring, on the other hand, is certainly able to adequately display the aesthetic properties of the stone and many would argue that the size is far more practical for everyday wear.
