What Is a 1 Carat Diamond?
A carat is a unit of weight used for gemstones, and 1 carat equals 200 milligrams or 0.2 grams. While this may not sound like much, a 1 carat
diamond is considered a significant size in jewelry,especially in engagement rings.It strikes a perfect balance between size,sparkle,andaffordability.
The Importance of a Diamond Price Chart
A diamond price chart helps consumers, investors, and jewelers understand market trends and make cost-effective choices. These charts display
the price range of 1 carat diamonds according to quality grades, allowing side-by-side comparisons. They are often updated monthly by industry
sources like Rapaport or IDEX.
The 4Cs and Their Influence on Price
Cut: A well-cut diamond enhances brilliance and light performance. Ideal or Excellent cut diamonds can cost significantly more than those with
Good or Fair cuts.Color: Graded from D (colorless) to Z (light yellow/brown). Colorless diamonds are rarer and more expensive. A 1 carat D color
diamond is worth far more than a J color diamond of the same cut and clarity.Clarity: Measures internal inclusions and external blemishes.Grades
range from Flawless (FL) to Included (I3). Higher clarity equals higher value.Carat: Since this chart focuses on 1 carat stones, weight is fixed,
but its combination with the other 3 Cs determines the final price.
