Carat Weight: How It Affects Diamond Price and Appearance
At AMIR AMIR, we understand that carat weight directly impacts diamond price and appearance, but it is not the only factor determining a diamond’s size or brilliance. Carat (ct) is the standard unit for measuring diamond weight, with one carat equal to 200 milligrams or 0.2 grams. Carat weight is divided into 100 points for precise measurement — for example, a 0.50-carat diamond is often called a “50-pointer.”
While carat weight is a crucial part of diamond valuation, at AMIR AMIR we always emphasize considering other essential factors like cut, color, and clarity, which define a diamond’s overall beauty and value.

🔹 Note: Prices vary based on market conditions, cut quality, color, and clarity.
Size vs. Weight: Why Diamonds of the Same Carat Can Look Different
According to the AMIR AMIR Diamond Specialists, the apparent size of a diamond depends on its cut and shape, meaning two diamonds with the same carat weight can look quite different:
• Round diamonds retain more weight in their depth, so they may appear slightly smaller from the top compared to other shapes.
• Oval, marquise, and pear shapes have elongated forms, creating the illusion of a larger size.
• Emerald and Asscher cuts may appear smaller due to their deep pavilion and step-cut facets.
The Setting: Make Your Diamond Look Bigger (or Smaller)
At AMIR AMIR, we believe your choice of setting can dramatically affect how large your diamond appears:
✔️ Halo settings encircle the center diamond with smaller stones, giving the illusion of a larger center diamond.
✔️ Bezel settings wrap the diamond in metal, which can make it look slightly smaller while adding protection.
✔️ Thin bands can make the center stone look more prominent and visually bigger.
Smart Buying: Choose Slightly Below Milestone Carat Weights
AMIR AMIR’s diamond advisors recommend purchasing just below popular milestone weights (e.g., 0.90 ct instead of 1.0 ct) to save significantly without a noticeable difference in appearance. Diamond prices jump at popular thresholds like 1.0 ct, 1.5 ct, and 2.0 ct — staying just below can offer exceptional value.
