What are carats?
Difference between Ct and Kt
Behind these two simple abbreviations lies a world of differences. The terms Ct and Kt, which might seem similar, actually represent completely different concepts in the jewelry industry. They refer to distinct values and characteristics of the jewelry we wear.
This article clarifies the distinction between carats for diamonds (Ct) and carats for gold (Kt), guiding you through the fascinating measurement systems used for precious jewelry.
Diamond Carat (Ct)
When we talk about diamonds and precious stones, the carat, abbreviated as Ct, refers exclusively to the weight of the stone. One carat equals exactly 0.2 grams. This measurement is fundamental in determining one of the most important aspects of a diamond’s value: its size.
The diamond measurement system is highly precise and further divides the carat into 100 points. This means a 0.75-carat diamond can also be described as a 75-point diamond.
1 Ct = 0.2 grams
1 Ct = 100 points
The famous 4Cs
Carat weight is only one of the four key parameters for evaluating a diamond, known in the industry as the "4Cs":
- Carat
- Cut
- Clarity
- Color
A larger diamond is not automatically more valuable than a smaller one if the other parameters are lower in quality. In jewelry featuring multiple diamonds, the total carat weight of all diamonds is often indicated.
Gold Carat (Kt)
The carat in gold, abbreviated as Kt, has a completely different meaning. Here, it does not refer to weight but to the purity of the precious metal. The gold carat system is based on a scale of 24 parts, where 24 carats (24 Kt) represent 100% pure gold.
Pure gold, although extremely valuable, is too soft for most jewelry applications. For this reason, it is usually alloyed with other metals to increase its hardness and durability, creating different alloys with varying purity percentages. These alloys not only improve gold’s physical properties but can also change its color, producing variations such as yellow, white, or rose gold, which are commonly used in our collections.
The most common gold alloys used are 18 Kt, 14 Kt, and 9 Kt gold.
Titanium, Gold and Diamonds
Jewelry is not only about beauty but also a balanced blend of history and science.
In the MANO | J. collections, the fusion of titanium, gold, and diamonds represents the essence of contemporary jewelry. Titanium, a lightweight yet extremely durable material, is paired with gold and diamonds to create pieces that unite innovation and tradition.
