Diamond Price Per Carat
Diamond prices vary significantly based on quality grades, and adjusting one or two grades can noticeably increase or decrease cost. As a starting point, we typically recommend diamonds with a Very Good cut, VS2 clarity, and G color, which offer a strong balance of sparkle, appearance, and value. With that pricing context in mind, here’s what you can expect to pay at different carat weights.
How Much Does a 1 Carat Diamond Cost?
Depending on quality choices, the price of a 1 carat diamond typically ranges from $500 to $16,000:
- A 1-carat natural diamond generally ranges from $1,000 - $16,000.
- A 1-carat lab-grown diamond typically ranges from $500 - $4,500.
At 1 carat, small changes in cut, color, or clarity can noticeably affect price, but many diamonds still appear eye-clean and near colorless at lower grades. Because inclusions and subtle warmth are harder to detect at this size, prioritizing cut often has the greatest impact on sparkle and overall appearance.
How Much Does a 2 Carat Diamond Cost?
Depending on quality choices, the price of a 2-carat diamond typically ranges from $1,000 to $46,000:
- A 2-carat natural diamond generally ranges from $3,500 - $46,000.
- A 2-carat lab-grown diamond typically ranges from $1,000 - $13,500.
At 2 carats, price per carat increases, making thoughtful trade-offs in color or clarity especially impactful. While color and inclusions become slightly more noticeable as size increases, choosing eye-clean clarity and near colorless grades helps preserve sparkle while managing cost.
How Much Does a 3 Carat Diamond Cost?
Depending on quality choices, the price of a 3-carat diamond typically ranges from $2,000 to $102,500:
- A 3-carat natural diamond generally ranges from $10,500 - $102,500.
- A 3-carat lab-grown diamond typically ranges from $2,000 - $35,000.
At 3 carats, rarity plays a larger role in pricing, and balanced quality choices become more important. Larger diamonds show more detail overall, so strong cut quality helps maintain brightness while carefully chosen clarity keeps inclusions discreet.
How Much Does a 4 Carat Diamond Cost?
Depending on quality choices, the price of a 4 carat diamond typically ranges from $3,000 to $136,000:
- A 4-carat natural diamond generally ranges from $19,500 - $136,000.
- A 4 carat lab-grown diamond typically ranges from $3,000 - $44,500.
At 4 carats, cut quality becomes especially noticeable because it strongly influences sparkle and how open the diamond appears. At this size, prioritizing cut often delivers more visual impact than increasing color or clarity grades.
How Much Does a 5 Carat Diamond Cost?
Depending on quality choices, the price of a 5-carat diamond typically ranges from $3,500 to $214,500:
- A 5-carat natural diamond generally ranges from $28,500 - $214,500.
- A 5-carat lab-grown diamond typically ranges from $3,500 - $72,000.
At 5 carats, availability becomes more limited, and flexibility across color, clarity, or shape opens up more options. Because very large diamonds amplify both color and inclusions, thoughtful trade-offs help maintain an impressive appearance without over-prioritizing technical grades.
