Understanding CTTW and CTW in Diamonds

When exploring the space of diamond jewelry, one encounters various terminologies and metrics used to describe the characteristics of these precious stones. Among these terms, two commonly encountered acronyms are CTTW and CTW, both referring to carat weight but with distinct meanings and implications. In this educational article, we will unpack the definitions of CTTW and CTW, their significance in diamond jewelry, and provide practical examples from reputable diamond jewelry vendors

CTTW and CTW Defined

CTTW, or Carat Total Weight, and CTW, or Carat Total Weight, are metrics used to measure the total weight of all diamonds present in a piece of jewelry. While the term “carat” typically refers to the weight of a single central diamond, CTTW and CTW encompass the combined weight of all diamonds, including any side stones or accent diamonds.

Curious about carat weight for diamonds? When shopping for that perfect sparkle, consider both CTW (Carat Total Weight) and CTTW (Carat Total Diamond Weight). Explore precision-cut lab-grown diamonds from trusted vendors particularly Whiteflash and James Allen.

Distinguishing CTTW/CTW from Carat

It’s crucial to differentiate between CTTW/CTW and the term “carat.” Carat denotes the weight of an individual diamond, usually the central stone in a piece of jewelry. Conversely, CTTW/CTW accounts for the cumulative weight of all diamonds incorporated into the jewelry item, providing a comprehensive measure of its overall diamond content.

Exploring Additional Considerations in Diamond Selection

In addition to carat weight, several other factors significantly impact the beauty, value, and overall quality of a diamond. The “Four Cs” – cut, color, clarity, and carat weight—collectively determine a diamond’s desirability and brilliance. The cut refers to the diamond’s proportions, symmetry, and polish, influencing its ability to reflect light and sparkle. Color grading assesses the absence of color in a diamond, with the highest-grade diamonds appearing colorless. Clarity evaluates the presence of internal flaws or blemishes that affect the diamond’s transparency and brilliance. Lastly, while carat weight measures a diamond’s size, it’s essential to consider these other factors to ensure the diamond’s overall beauty and value align with individual preferences and budget constraints.

Examples from Leading Diamond Retailers

  1. Whiteflash

Whiteflash offers an array of diamond jewelry, including engagement rings and earrings. For instance, a Whiteflash engagement ring featuring a 1-carat center diamond surrounded by smaller accent diamonds with a total weight of 0.5 carats would have a CTTW of 1.5 carats.

  1. James Allen

James Allen showcases diverse ring designs, some adorned with pavé or halo-set diamonds. Consider a James Allen pavé engagement ring embellished with 36 small round diamonds totaling 0.25 carats. With the addition of a 1-carat center stone, the CTTW would amount to 1.25 carats.

  1. Blue Nile

Blue Nile presents a wide selection of diamond rings catering to various preferences. In a solitaire setting from Blue Nile featuring a 1-carat diamond, the CTTW would equal the carat weight of the central stone, which is 1.00 carat. Alternatively, a halo diamond pendant with a total carat weight of 0.51 carat, inclusive of a 1-carat center stone, offers an elegant yet cost-effective option.

  1. Adiamor

Adiamor offers finely designed diamond jewelry, including rings and earrings. For example, an Adiamor diamond halo earrings adorned with 36 round natural diamonds totaling 0.20 carats, combined with a 1-carat center stone, would have a CTTW of 1.20 carats, showcasing substantial brilliance and elegance.

Significance in Diamond Pricing

While the price of a diamond tends to increase exponentially with its carat weight due to rarity, the relationship between a jewelry item’s CTTW/CTW and its value is not linear. While a higher CTTW/CTW can enhance the overall aesthetic appeal of a piece, the value is primarily influenced by factors such as the quality of individual diamonds, including cut, color, and clarity.
