Frequently Asked Questions
Is a 4 carat lab grown diamond considered an extra-large or statement size? +
Yes. A 4 carat diamond is a true statement size with major visual impact. It offers
exceptional finger coverage and instantly stands out, making it ideal for bold engagement
rings and high-luxury jewellery pieces.
How large does a 4 carat diamond look compared to 2 or 3 carat diamonds? +
A 4 carat diamond is not just “one carat more” than a 3 carat — the face-up area and overall
presence increase significantly. Depending on shape and cut, a 4 carat stone can look
around 20–30% larger than a 3 carat and dramatically larger than a 2 carat diamond on the hand.
Are 4 carat lab grown diamonds much more affordable than mined diamonds of the same size? +
Yes. In larger sizes, the price gap becomes even more visible. A 4 carat lab grown diamond
can cost a fraction of a comparable mined diamond, allowing you to prioritise size, cut, and
quality without the extreme price of natural stones at this carat weight.
Do 4 carat lab grown diamonds sparkle as much as natural diamonds of the same size and grade? +
Absolutely. Lab grown diamonds have the same chemical composition and crystal structure as
mined diamonds. A well-cut 4 carat lab grown diamond will deliver the same brilliance, fire,
and scintillation as a natural diamond of identical specifications.
Which color and clarity grades are recommended for a 4 carat diamond? +
In a 4 carat size, inclusions and color are easier to see. Many buyers prefer
D–F color and VVS1–VS1 clarity to keep the diamond looking bright and clean.
However, an excellent or very good cut is essential for maximising light performance and beauty.
Are 4 carat lab grown diamonds certified by IGI or GIA? +
Yes. 4 carat lab grown diamonds typically come with certification from respected gemological
laboratories such as IGI or GIA, with detailed grading reports covering the diamond’s 4Cs,
proportions, and growth method (CVD or HPHT).
Is a 4 carat diamond practical for everyday wear in an engagement ring? +
A 4 carat diamond can be worn daily, but the setting becomes very important.
Secure designs like strong prongs, bezel, or halo settings help protect the stone and
keep it stable, while ensuring it feels comfortable despite its larger size and height.
Which shapes look best in the 4 carat range for lab grown diamonds? +
Round, oval, emerald, radiant, and pear shapes are especially popular at 4 carats.
Ovals, pears, and marquise maximise apparent size and finger coverage, while round and emerald
cuts emphasise balance, symmetry, and either maximum brilliance or elegant step-cut reflections.
Is a 4 carat lab grown diamond a good choice for pendants and high jewellery pieces? +
Yes. A 4 carat solitaire makes an exceptional pendant or centre stone in high jewellery designs.
It offers dramatic presence and can be the focal point of a bespoke necklace, cocktail ring,
or red-carpet style piece.
Are there many options available in 4 carat lab grown diamonds? +
Yes. You can choose from multiple shapes (round, oval, emerald, radiant, cushion, pear,
marquise, fancy cuts), a wide range of color and clarity grades, and different growth methods,
allowing you to tailor the 4 carat diamond to your exact style and budget.
