Frequently Asked Questions
What is a Portuguese cut lab grown diamond? +
A Portuguese cut lab grown diamond is a specialty round-style diamond with a high facet count
and a distinctive, intricate pattern across the crown. It is designed to create lively sparkle
and strong light return, offering a look that feels more detailed than a standard round brilliant.
How is a Portuguese cut different from a round brilliant cut? +
A round brilliant cut is optimised for maximum brightness with a classic facet arrangement.
A Portuguese cut uses additional facets and a more complex facet layout, creating a more
decorative “mosaic” look and a different style of scintillation (sparkle pattern).
Do Portuguese cut lab grown diamonds sparkle more? +
They can appear especially lively because the extra facets break light into smaller flashes.
Sparkle depends on cut precision, symmetry, and proportions, so choosing a well-cut stone is key
for the best brightness and fire.
Are Portuguese cut lab grown diamonds real diamonds? +
Yes. Portuguese cut lab grown diamonds are 100% real diamonds with the same chemical structure,
hardness, brilliance, and fire as mined diamonds. The difference is only the origin (lab-created)
and the cutting style.
Are Portuguese cut lab grown diamonds IGI certified? +
Many Portuguese cut lab grown diamonds are available with IGI certification. The grading report
outlines the 4Cs (cut, colour, clarity, carat), measurements, proportions, and laser inscription
details, helping you compare stones confidently.
What should I check when buying a Portuguese cut lab grown diamond? +
Focus on overall cut quality (polish and symmetry), proportions, and face-up appearance.
Because Portuguese cuts have more facets, strong symmetry and clean finishing are especially
important for an even pattern and attractive sparkle.
Does the extra faceting hide inclusions better? +
Additional facets can sometimes help disperse reflections and reduce how noticeable small inclusions
appear face-up. However, clarity is still important—choose a clarity grade that looks clean to your eye
for the size you prefer.
Are Portuguese cut lab grown diamonds durable for everyday wear? +
Yes. Lab grown diamonds rank 10 on the Mohs scale, just like natural diamonds. With proper care,
a Portuguese cut diamond is suitable for everyday wear and maintains its brilliance over time.
Do Portuguese cut lab grown diamonds cost more than standard round cuts? +
Pricing depends on carat weight, colour, clarity, and overall finishing. Portuguese cuts can sometimes
be priced differently due to specialty cutting and availability, but lab grown diamonds generally offer
strong value compared to mined diamonds at similar quality levels.
Do Portuguese cut lab grown diamonds come in different sizes and qualities? +
Yes. Portuguese cut lab grown diamonds are available across a wide range of carat weights, colour grades,
and clarity grades. Availability can vary, so filtering by your preferred 4Cs helps you quickly find the best match.
