Question: how much is a one and a half carat diamond?
Answer: A 1.5-carat diamond is about twice the price of a 1-carat diamond. A 1.5-carat stone can cost anywhere between $5,000 and $40,000. The price depends on the quality of the stone. Flawless and colorless 1.5-carat diamonds will cost many times more than diamonds with visible flaws and a yellow tint.
