A 5.4 Carat diamond currently has a price ranging from 3 billion VND to over 10 billion VND, depending on its color, clarity, and cut. This is a large-sized diamond (over 11 mm), belonging to the luxury segment for collectors and the elite. In this article, Jemmia Diamond will provide a detailed price list, accurate size conversion, and tips for choosing the most perfect 5.4 Carat diamond.
How much does a 5.4 carat diamond cost?
The price of a 5.4 Carat diamond commonly ranges from 3,500,000,000 VND to over 12,000,000,000 VND, strictly depending on the GIA certificate and the 4Cs standard.

5.4 Carat diamonds with Color D and IF clarity are "Unique" stones. These masterpieces often need to be pre-ordered from major diamond distribution centers worldwide such as Antwerp (Belgium) or Mumbai (India) due to their extremely limited quantity, not always being in stock.
Understanding the Size of a 5.4 Carat Diamond
A 5.4 Carat diamond is equivalent to a size of approximately 11.2 mm – 11.5 mm (over 11 ly) and weighs exactly 1.08 grams. Many people often confuse weight (Carat) with size (ly); below are the accurate conversion specifications:
- Weight: According to international standards, 1 Carat = 0.2 grams, so a 5.4 Carat diamond will weigh exactly 1.08 grams.
- Size (Ly): A standard Round 1 Carat diamond usually has a diameter of 6.5 ly. However, as the weight increases, the diameter does not increase proportionally. A perfectly balanced 5.4 Carat diamond will have a diameter of about 11.3 ly.
- Application: With a large size of over 11 ly, this stone creates a brilliant and opulent presence, often preferred for crafting into pendants or exquisite large-frame diamond rings.

Factors for Valuing a 5.4 Carat Diamond According to GIA Standards
To accurately determine the price of a 5.4 Carat diamond, experts rely on the 4Cs criteria:
- Color: From grade D (colorless) to Z (light yellow). At a large size of 5.4 ct, color D is the rarest and most expensive.
- Clarity: Because the surface of the stone is large, impurities are easily visible. Therefore, stones meeting VVS1 or IF standards always have extremely high collectible value.
- Cut: Only stones with an Excellent cut grade can ensure maximum light reflection, making the 11 ly stone brilliantly sparkly.
- GIA Certificate: This is the mandatory "birth certificate" to ensure the transfer value and sustainable investment of the stone.
