🇦🇪 Why Dubai Often Has Better 1ct Lab Diamond Prices

Dubai continues to be one of the most competitive 1 carat lab grown diamond price markets globally due to:

• Tax-free jewellery regulations

• High competition among wholesalers and retailers

• Strong links to cutting and polishing hubs

• Lower operational overhead compared to many Western cities
  

For buyers comparing a 1ct lab diamond between the USA, UK, and UAE, Dubai often delivers either better specs for the same budget or lower cost for similar quality.

The 1ct lab-grown diamond price you see online or in-store is mainly driven by four key factors: cut, color, clarity, and shape. Each of these changes how the stone looks and what it costs.

Cut is the single biggest driver of how beautiful a 1ct diamond looks.

• Ideal Cut → Maximum brilliance, fire, and symmetry

• Excellent Cut → Strong sparkle and reliable performance

• Very Good Cut → More budget-friendly, still attractive

👉 Expert Rule: On a 1-carat diamond, never sacrifice cut just to push carat or clarity higher. A well-cut 1ct lab diamond with excellent proportions will almost always look better than a poorly cut stone with “higher” paper specs.

Color grading runs from D (colorless) down the scale. For 1 carat lab grown diamond price planning, you want a balance of brightness and budget.

Most global buyers choose between G–H when they want a bright look without paying for “paper perfection.”

Clarity tells you how visible internal inclusions and external marks are.

For a 1ct lab-grown diamond price sweet spot, VS1–VS2 is often the smartest range—especially with a good cut and color.

Different shapes use different amounts of rough diamond, which affects cost.

• Round — Highest cutting loss → higher price

• Oval, pear, marquise — More surface area per carat → look bigger

• Emerald — Step-cut style → shows clarity more clearly

Shape choice influences both the look and final 1ct lab diamond price you pay.

Here’s how common shapes compare in 2025 for a 1ct IGI or GIA certified lab diamond with good cut and mid-to-high grading:
