    Frequently Asked Questions +
    Is a 3 carat lab grown diamond considered a luxury size? +
    Yes. A 3 carat diamond is widely regarded as a luxury, high-impact size. It has a commanding presence, exceptional visibility, and is often chosen for premium engagement rings, statement solitaires, and upscale fine jewellery pieces.
    How large does a 3 carat diamond look compared to a 2 carat or 1 carat diamond? +
    A 3 carat diamond appears significantly larger — not just by weight, but by surface area. Depending on the shape, a 3 carat stone can look 40–60% larger than a 2 carat, and more than double the visual size of a 1 carat diamond.
    Are 3 carat lab grown diamonds more affordable than mined diamonds of the same size? +
    Yes — the cost difference is substantial. A 3 carat lab grown diamond can be up to 70–80% more affordable than a mined diamond of the same cut, clarity, and color, making large diamonds more achievable for modern buyers.
    Do 3 carat lab grown diamonds sparkle as much as natural diamonds of the same size? +
    Absolutely. Since lab grown diamonds are real diamonds with identical physical and optical properties, a well-cut 3 carat stone will offer exceptional brilliance, fire, and scintillation just like a natural diamond of equivalent quality.
    Which clarity and color grades are recommended for a 3 carat diamond? +
    Larger diamonds show inclusions more easily, so most buyers prefer D–F color and VVS1–VS1 clarity to maintain a bright, clean look. However, cut quality should always be the top priority for maximizing light performance.
    Do 3 carat lab grown diamonds come with IGI or GIA certification? +
    Yes. Most 3 carat lab grown diamonds are certified by leading gemological laboratories such as IGI or GIA, ensuring transparency on the diamond’s 4Cs, polish, symmetry, and growth method.
    Are 3 carat diamonds practical for everyday wear in engagement rings? +
    Yes — as long as they are set securely. A strong setting such as a 4-prong, 6-prong, bezel, or cathedral design helps protect the stone while maintaining comfort and stability for daily wear.
    Which shapes look biggest in the 3 carat range? +
    Shapes like oval, pear, radiant, emerald, and marquise appear especially large due to their elongated proportions and larger face-up area, while round diamonds emphasize brilliance and fire more than apparent size.
    Is a 3 carat lab grown diamond good for pendants or earrings? +
    Definitely. A 3 carat solitaire makes a luxurious pendant with a bold presence, and 1.5 carat each stones create premium stud earrings with excellent sparkle and balance.
    Are there many options available in the 3 carat lab grown diamond category? +
    Yes. You can choose from a wide selection of shapes (round, oval, emerald, radiant, pear, cushion, marquise, princess, fancy shapes), clarity grades, colors, and cut qualities within the 3 carat range, making it easy to find one that suits your style and budget.
