A 7-carat diamond is considered one of the rare and highly valuable gemstones on the market. Weighing 1.4 grams, a 7-carat diamond often appears in high-end jewelry designs and is especially favored by the elite. So, how much does a 7-carat diamond cost, how many millimeters does it correspond to, and why is it so rare? Let’s find out in the article below.
What is a 7-carat diamond?
A 7-carat diamond is a stone weighing 1.4 grams (based on the conversion 1 carat = 0.2 grams). This is a large weight, far exceeding the common 1–3 carat diamonds often seen in the jewelry industry.
Naturally occurring diamonds that reach 7 carats are very rare, usually accounting for only an extremely small percentage of the total number of diamonds mined globally. For this reason, they always hold high value and are sought after by collectors as well as the ultra-wealthy.

How many millimeters is a 7-carat diamond?
A standard round 7-carat diamond usually has a diameter of about 12.3 - 12.5 ly (mm). In the Vietnamese market, instead of only referring to carats, many customers often call diamond size by the unit “ly” (mm).
- If converted, 1 ly = 1 mm → a 7-carat diamond corresponds to 12.3 mm - 12.5 mm.
- Depending on whether the cut is shallow or deep, the number may vary slightly but will still remain within the above range.
This shows that a 7-carat diamond is very large in size and difficult to find on the market.

How much does a 7-carat diamond cost?
The price of a 7-carat diamond on the market is flexible, starting from 3 to 15 billion VND, specifically:
- 7-carat diamond, color D, clarity IF, cut Excellent → about 8–15 billion VND or more.
- 7-carat diamond, color F – G, clarity VVS or VS → about 5–9 billion VND.
- 7-carat diamond, color H and below, clarity SI → the price can range from 3–5 billion VND.
The value of a 7-carat diamond is not fixed, but depends on quality according to the international 4Cs standard. With the same 7-carat weight, a stone’s value can differ greatly based on these four factors.
The deciding factors include:
- Color: D color (completely colorless) is the most expensive, and as it goes down through grades E, F, G… the price decreases.
- Clarity: the fewer inclusions a 7-carat diamond has and the more transparent it is, the more expensive it is.
- Cut: An Excellent cut helps maximize brilliance, significantly increasing the diamond’s value.
