What is the price of a 1.5-carat diamond?

The 1.5-carat diamond occupies a sought-after position: significantly larger than a 1-carat, more accessible than a 2-carat. Its value, like any gem, depends on the 4Cs — weight, color, clarity, cut — and its certificate. Here are the benchmarks to understand its price and resell it well.

What exactly is a 1.5-carat diamond?

1.5 carats corresponds to 0.30 grams, or approximately 7.4 mm in diameter in round brilliant cut — a marked visual presence on the finger. At this weight, the rarity of fine stones increases: supply diminishes, which supports prices.

How is the price of a 1.5-carat diamond determined?

Color, clarity and cut quality cause significant price variations for the same weight. Added to this is the threshold effect: the 1.50-carat threshold marks a price-per-carat jump compared to 1.30 or 1.40 carats, for the same quality.

In practice, the value of a 1.5-carat diamond falls between the ranges of our guides for 1-carat and 2-carat diamonds — the difference depending mainly on color and clarity. The GIA certificate remains the element that best secures valuation.
