How Many Carats Is a 6.4 Ly Diamond?
In the jewelry industry, “ly” is the term used for a diamond’s diameter measured in millimeters. Therefore, a 6.4 ly diamond = 6.4mm. When converted to the international carat standard, this diamond usually weighs about 1.0 carat. Depending on the depth and cut proportions, the actual weight may range from 0.98 - 1.05 carat.
A 6.4 ly diamond equals 1.0 Carat
The ~1 carat size is considered the “gold standard” in the jewelry world. It is large enough to stand out and look luxurious, yet still moderate enough to suit many styles and budgets. Therefore, 6.4 ly diamonds are favored for engagement rings, wedding rings, and high-end jewelry designs.
The Meaning of a 6.4 Ly Diamond
In the West, the number 6 is often associated with luck, balance, and harmony. Meanwhile, in the East, especially in Chinese culture, the number 6 is highly regarded because its sound evokes the word “prosperity,” symbolizing luck and smoothness, especially in business transactions.
As for the number 4, in Western culture it is often considered a symbol of stability, solidity, steadfastness, and reliability.

Therefore, in folk belief, choosing items related to these two numbers, such as a 6.4 ly diamond, is considered to possess a symbol of luck, bringing prosperity and abundance. Moreover, the combination of these two numbers not only symbolizes material wealth but also reflects spiritual prosperity, creating a special connection between the material and the spiritual in the concept of blessings and happiness.
What Is the Current Price of a 6.4 Ly Diamond?
Each diamond is considered a completely unique work of art. The value of a gemstone is not determined only by weight but must also be evaluated based on the 4C standard, including clarity, color, and cut quality. However, no two diamonds have exactly the same specifications except for cut. Therefore, it is very difficult to price them when you only provide information about carat weight.
According to the natural diamond market in Vietnam today, the reference price for a 6.4 ly diamond is as follows:
- 6.4 ly diamond, Excellent cut, D color, VVS1 clarity: approximately 120 - 150 million VND and up
