What Is CTW Diamond?

Diamonds have long been cherished for their exquisite beauty and enduring symbolism. When it comes to buying a diamond, you may come across the term “CTW” or “Carat Total Weight.” But what exactly does CTW mean, and how does it impact the value and appearance of a diamond? In this blog, we’ll explore the concept of CTW diamonds and unravel the secrets behind their allure.

What Is CTW Diamond?

CTW, or Carat Total Weight, refers to the total weight of all the diamonds in a piece of jewelry, rather than the weight of a single diamond. In other words, it accounts for the combined weight of all the diamonds used in a particular setting or design.

A CTW diamond is not a single, large diamond; instead, it is composed of several smaller diamonds that are either set close together or scattered across a piece of jewelry, such as a ring, necklace, bracelet, or earrings. These smaller diamonds, known as “diamond accents” or “side stones,” complement a central, larger diamond or gemstone, enhancing its overall appearance and sparkle.

  3. Versatility: CTW diamonds are incredibly versatile and can be incorporated into various jewelry designs, from classic solitaire rings to intricate, artistic settings.
  4. Personalization: Designers and jewelers can use CTW diamonds to create unique and personalized jewelry pieces, tailoring them to individual preferences and style.

When considering CTW diamond jewelry, there are several factors to keep in mind:

  1. Budget: Determine your budget and explore CTW options that align with your financial considerations.
  2. Quality: Assess the quality of the central diamond (if present) and the side stones, considering the Four Cs: Carat Weight, Cut, Color, and Clarity.
  3. Setting: Pay attention to the design and setting of the jewelry, as it can significantly impact the overall aesthetic and wearability.
  4. Certification: Ensure that the diamonds in your CTW jewelry come with appropriate certifications, verifying their authenticity and quality.


CTW diamonds are a brilliant way to enjoy the timeless beauty of diamonds without the expense of a single, large carat stone. They offer versatility, affordability, and the opportunity to create personalized, eye-catching jewelry pieces. Whether you’re considering a CTW diamond engagement ring, a necklace, or a pair of earrings, the allure of CTW diamonds lies in their ability to enhance your style and capture the essence of everlasting elegance and sophistication.


Is A CTW Diamond Real?

CTTW refers to the weights of the diamonds in a ring. If you’re interested in, say, a sapphire and diamond engagement ring, the CTTW doesn’t consider the sapphires. Important to note: Companies that use lab-made diamonds still use CTTW, so it isn’t necessarily a measure of just real diamonds.

What Does 1 CTW Diamond Mean?

For instance, 1 CTW diamond ring means the total weight of diamonds in the ring will be 1 carat. If you have an engagement ring with a centerpiece diamond weighing 1 carat and side diamonds of 0.50 carats each, then the CTW will be 1 + 0.50 + 0.50 = 2 CTW.

What Does 2.00 CTW Mean?

“carat weight” refers to the weight of one given stone. “total carat weight” refers to the sum total of multiple stones. For example, a three stone ring that has a 1 CT diamond centerstone and two ½ carat sidestones is a 2 CTW ring.
