With remarkable sparkle and precise craftsmanship, a 5 carat diamond stands out as a premium choice for collectors and those seeking a bold centre stone.

    Frequently Asked Questions +
    Is a 5 carat lab grown diamond considered a high-luxury size? +
    Yes. A 5 carat diamond sits firmly in the high-luxury category. It offers exceptional presence, dramatic finger coverage, and is commonly seen in ultra-premium engagement rings and fine high jewellery collections worldwide.
    How big does a 5 carat diamond look compared to a 3 or 4 carat diamond? +
    A 5 carat diamond looks significantly larger — both in weight and visual size. Depending on the cut, it can appear 20–30% larger than a 4 carat and nearly twice the face-up area of a 3 carat diamond, making it a true showstopper on the hand.
    Are 5 carat lab grown diamonds much more affordable than mined diamonds at this size? +
    Extremely. Large mined diamonds rise exponentially in price, while lab grown diamonds remain far more accessible. A 5 carat lab grown diamond can cost up to 80–90% less than a mined diamond of equal cut, clarity, and color, without compromising brilliance or quality.
    Do 5 carat lab grown diamonds sparkle the same as natural 5 carat diamonds? +
    Yes. Lab grown diamonds have the same chemical and optical properties as natural diamonds. When well-cut, a 5 carat lab grown diamond will offer identical brilliance, fire, and scintillation to a natural diamond of the same grade.
    What clarity and color grades are best for a 5 carat diamond? +
    At larger sizes, imperfections and color become more visible. Buyers typically choose D–F color and VVS1–VS1 clarity for a clean, impressive look. However, cut quality remains the most important factor for maximizing beauty.
    Are 5 carat lab grown diamonds certified by IGI or GIA? +
    Yes. Most 5 carat lab grown diamonds come with IGI or GIA certification, detailing all 4Cs, growth method (CVD or HPHT), fluorescence, polish, and symmetry.
    Is a 5 carat diamond suitable for everyday wear in an engagement ring? +
    A 5 carat diamond can be worn daily, but the setting must be secure. Designs like strong prongs, double prongs, bezels, or halo settings ensure stability and protect the diamond, especially given its larger size and height.
    Which shapes look best in the 5 carat size range? +
    Oval, radiant, emerald, pear, round, and cushion cuts are especially popular at 5 carats. Elongated shapes (oval, pear, marquise) offer maximum finger coverage, while round and emerald cuts highlight perfect symmetry and brilliance.
    Are 5 carat lab grown diamonds a good choice for pendants or earrings? +
    Yes. A 5 carat solitaire pendant makes a dramatic luxury statement, and 2.5 carat each diamonds create ultra-premium stud earrings with unmatched presence and brilliance.
    Do 5 carat lab grown diamonds come in many shapes, colors, and clarity options? +
    Yes. The 5 carat category offers a wide range of shapes — including round, oval, emerald, radiant, cushion, pear, marquise, and fancy cuts — along with several color, clarity, and cut-grade options to suit your desired style and budget.
