Factors that determine the price of a 4 ly 3 diamond

In fact, rough diamonds after being mined and cut are called polished diamonds. Therefore, to price a polished diamond as well as a diamond, it is necessary to rely on the 4Cs standard including 4 basic quality factors: Cut (Cut), Color (Color), Clarity (Clarity), Weight (Carat). The way to estimate the price of a polished diamond is as follows:Weight (Carat): A 4 ly 3 diamond corresponds to about 0.3 carat. In diamonds, a stone with greater weight (even just 0.01ct) always has significantly higher value due to its rarity.

• Color: Scale from D to Z. Stones with D color (Pure white) are always the most expensive. Stones with a yellowish tint (J, K, L color grades) will have lower prices.
• Clarity: Stones with IF (Internally Flawless) or VVS1/VVS2 clarity are very rare, helping the diamond shine to the fullest and have high liquidity.
• Cut: Only stones with an Excellent cut can reflect light perfectly according to the golden ratio, creating brilliant fire for the jewelry piece.
