Factors determining the price of a 4.3mm diamond

In fact, rough diamonds, after being mined and processed, are called faceted diamonds. Therefore, to price faceted diamonds as well as diamonds, it is necessary to rely on the 4Cs standard, which includes 4 basic quality factors: Cut, Color, Clarity, and Carat weight. The method of estimating the price of a faceted diamond is as follows: Carat weight: A 4.3mm diamond corresponds to approximately 0.3 carats. In diamonds, a larger stone (even by just 0.01ct) is always significantly more valuable due to its rarity.

• Color: Scale from D to Z. Stones with D color (pure white) are always the most expensive. Stones that lean towards yellow (J, K, L color) will be cheaper.
• Clarity: Stones with IF (Internally Flawless) or VVS1/VVS2 clarity are very rare, allowing the diamond to sparkle maximally and have high liquidity.
• Cut: Only stones with an Excellent cut reflect light perfectly in the golden ratio, creating a brilliant fire for the jewelry.
