    Before choosing jewelry, it is important to understand the stones themselves. From high-end to affordable options, the four types of stones most commonly used today each possess an irresistible charm.

    ✦ Natural

    Natural
    Diamond

    The ultimate luxury. A carbon crystal with a hardness of 10.0, nurtured by the Earth over billions of years. The king of gemstones, offering eternal brilliance that can never be scratched.

    Hardness 10.0
    Origin Natural
    Value Premium
    ✦ Recommended for: Special gifts that last a lifetime, such as engagement rings or major milestones.
    L ⬡ Lab-Grown

    Lab-Grown
    Diamond

    A true diamond born in a laboratory. It shares the same chemical composition and crystal structure as a natural diamond but at a more affordable price point and with a wider variety of colors. It is a "real" diamond—just created in a different environment.

    Hardness 10.0
    Origin Lab
    Value Best Value
    ✦ Recommended for: Those who want to enjoy authentic diamonds at a reasonable price or are looking for unique colors.
    ◈ Moissanite

    Moissanite

    A stone that releases intense rainbow brilliance—its dispersion is even higher than that of a diamond. With a hardness of 9.5 and a price less than one-fourth of a natural diamond, it is currently gaining attention as a top-tier alternative.

    Hardness 9.5
    Sparkle Rainbow Fire
    Price ~1/4 of Natural
    ✦ Recommended for: Those who seek dazzling sparkle or want to enjoy a larger stone within the same budget. Durability is nearly flawless.
    ◇ CZ

    Cubic Zirconia
    (CZ)

    The most affordable alternative. While it is prone to scratches due to lower hardness (8.5), its high decorative appeal makes it perfect for jewelry featuring many small stones. A sparkle you can enjoy casually.

    Hardness 8.5
    Color Variety
    Price Accessible
    ✦ Recommended for: Trendy fashion jewelry, small gifts, and everyday accessories.
