A 3.6mm diamond is a popular choice due to its moderate size, suitable for various delicate jewelry designs like rings, earrings, or pendants. However, the price of a 3.6mm diamond also depends on the 4Cs standard (Carat, Cut, Color, Clarity) and its accompanying grading certificate. In this article, Jemmia updates the latest 3.6mm diamond price list on the current market. It also helps you understand how to convert mm to carats and provides tips for choosing a beautiful and accurately valued 3.6mm diamond.
How much does a 3.6mm diamond cost?
A 3.6mm diamond has a wide price range, depending on factors such as weight (carat), cut, color, clarity, certification (GIA/IGI), and origin. High-quality diamonds (e.g., D color, VVS clarity) are typically many times more expensive than those with lower specifications.
The current market price for a 3.6mm diamond in Vietnam ranges from 6.3 million to 12.7 million VND, depending on the diamond 4Cs standard and origin. Below is the price list for 3.6mm diamonds according to the 4Cs standards of the Gemological Institute of America:

How many carats is a 3.6mm diamond?
In the jewelry industry, "ly" (mm) is used to measure size, while "carat" (ct) is a unit of weight (1 carat = 0.2g). With a size of 3.6mm, a diamond typically weighs around 0.17 carats, ranging from 0.165 - 0.175ct depending on the cutting proportions and depth.
At this weight, a 3.6mm diamond offers a delicate and elegant beauty, suitable for engagement rings, wedding bands, earrings, or pendants. However, due to its small size, its liquidity and investment value are not as high as stones from 0.20ct and above. Therefore, this type of diamond is usually chosen for jewelry rather than long-term investment.

Should you buy a 3.6mm diamond?
A 3.6mm diamond is a popular choice due to its delicate, elegant beauty and accessible price. However, whether you should buy one depends on your intended use.
Advantages:
- Compact size, offering a refined look when crafted into rings, earrings, or pendants.
- More affordable than larger sizes, suitable for personal jewelry needs.
- Easily incorporated into many simple engagement or wedding ring designs.
Disadvantages:
- Weighing only 0.17ct, its liquidity is low, making it less favored for investment.
- Its value appreciation over time is not as high as stones from 0.20ct and above.
- When set, small diamonds are often less prominent unless combined with intricate designs.
Therefore, a 3.6mm diamond is very suitable for those seeking a refined, affordable stone for commemorative jewelry or gifts. However, if you are looking for long-term value retention and liquidity, consider larger diamonds to ensure investment potential and lasting value.
