How much does a 2 ly diamond cost?
Because 2 ly diamonds belong to the melee diamond group, they are usually priced by carat or gram, instead of by individual stone like center diamonds. For 2 ly diamonds, the size is very small, so the 4C standards (Carat, Cut, Color, Clarity) are not too strict.
Their value mainly depends on total weight, consistency in size, color, clarity, and whether their origin is natural or synthetic. Below is a reference price list for types of 2 ly diamonds on the market that you should know:
- Standard natural 2 ly diamonds: 300,000 - 700,000 VND/stone
- High-end natural 2 ly diamonds (color D - F, clarity VVS - IF): From around 1,000,000 VND/stone
- Lab-grown 2 ly diamonds: 200,000 - 500,000 VND/stone.
Note: These are estimated prices and may change depending on the time and supplying brand.

Factors affecting the price of 2 ly diamonds
If you are interested in diamonds, you have probably heard of the 4 basic quality assessment factors: Carat (weight), Cut, Color, and Clarity. These are important criteria when evaluating large diamonds. However, with 2 ly melee diamonds that are very small in size, distinguishing color or clarity with the naked eye is almost impossible to do with absolute accuracy. The cut of this group is also not too diverse, mainly round (Round) to ensure easy matching when set into jewelry.

Factors affecting the value of 2 ly diamonds
In the melee diamond segment, the most important factor and the one that most affects price is uniformity. The stones need to have similar size, color, and clarity so that when set on the product, the overall appearance is harmonious and achieves high aesthetic value. Therefore, consistency among multiple stones is often more important than the individual 4C value of each stone.
However, the price of 2 ly diamonds is still affected by the above factors, including:
- Carat (weight): Although the weight is small, the total weight of the stones in a lot still affects the price.
- International certification: Such as GIA or IGI, helping ensure quality and transparent value.
- Origin, brand, and reputable sellers provide standard pricing along with clear warranty and trade-in policies.
