What factors affect the price of an 8.1 ly diamond?
The price of an 8.1 ly diamond is not fixed but depends on many quality factors according to international standards. Among them, the most important is the set of 4Cs criteria recognized by the Gemological Institute of America (GIA), specifically including:
Carat (Weight)
An 8.1 ly diamond has a diameter of approximately 8.1 mm, equivalent to an approximate weight of 2.0 – 2.2 carats (depending on cut proportions). At a large carat threshold like 2 carats, diamond prices increase exponentially due to high rarity and strong demand. Even a small difference in carat can create a significant price difference.
Cut
Cut is the factor that directly affects the sparkle and overall beauty of the diamond. An 8.1 ly diamond with an Excellent cut will reflect light optimally, creating a brilliant effect and having significantly higher value than stones with a Good or Fair cut.

Color
Diamond color is evaluated on a scale from D (colorless) to Z (noticeably yellowish).
- Group D–F (Colorless): Has the highest value, with nearly perfect transparency.
- Group G–H (Near Colorless): Still retains pure beauty but at a more “accessible” price point.
For an 8.1 ly diamond, D, E, and F color grades are always preferred because they fully enhance the size and brilliance of the stone.
Clarity
Clarity reflects the level and size of inclusions inside the diamond. Due to its large size, an 8.1 ly diamond reveals inclusions more easily, so grades such as VVS1, VVS2, or IF usually have the highest value. The higher the clarity of the diamond, the higher the price.
In addition, the price of an 8.1 ly diamond is also affected by the increasingly scarce supply of large natural diamonds, while demand continues to rise. This causes the price of an 8.1 ly diamond to tend to fluctuate and increase over time, especially for high-quality stones.
Meaning of an 8.1 ly diamond
According to feng shui beliefs and numerological symbolism, 8.1 has a total value of 9, representing eternity, longevity, and completeness. The number 9 has long been considered a symbol of durability, prosperity, and longevity.
Therefore, an 8.1 ly diamond is often chosen for:
- High-end engagement rings
- Wedding anniversary rings
- Jewelry marking career success milestones
