About Us

Grown Leo is a fine jewelry brand specializing in moissanite and lab-grown diamond jewelry: engagement rings, wedding bands, earrings, bracelets, pendants and loose stones. Since 2024 we've been making brilliant, beautifully made jewelry more accessible, without the price tag or the mining footprint of natural diamonds. As a direct jewelry manufacturer, we design and make our pieces ourselves and sell them straight to you, with no middlemen in between.

What we make

Every Grown Leo piece is made to order. We set each stone and finish each piece only after you place your order, so it's crafted for you rather than pulled from a warehouse shelf.

• Moissanite jewelry: moissanite engagement rings, wedding bands, earrings and loose moissanite stones. Moissanite is a lab-created gemstone known for its fire and its hardness (9.25 on the Mohs scale), which makes it ideal for everyday wear.
• Lab-grown diamond jewelry: lab-grown diamond engagement rings, wedding bands, earrings and IGI-certified loose lab-grown diamonds. Lab-grown diamonds are real diamonds: chemically, physically and optically the same as mined diamonds.
• Metals: 10K, 14K and 18K gold in yellow, white and rose, plus 925 sterling silver and platinum on selected designs.

Why Grown Leo

• Direct from the manufacturer. We make our own jewelry and sell it directly to you, with no middlemen, distributors or retail markups. You pay for the piece, not a supply chain.
• Made to order, made to last. Pieces are handcrafted after you order, typically in 3–14 business days, then shipped in 3–7 business days.
• Free worldwide shipping on every order, with no minimum. See our shipping policy.
• Certified lab-grown diamonds. Our loose lab-grown diamonds come with IGI certification, so you know exactly what you're buying.
• Your design, your way. Choose your setting, stone shape, carat and metal, or ask us about a custom engagement ring.
• Honest guidance. We publish free, plain-English guides so you can buy with confidence. Good places to start: moissanite vs diamond, lab-grown vs natural diamonds, the 4Cs of diamonds, how to check a GRA moissanite report and our ring size chart.

The story behind the name

Grown Leo brings together two ideas. "Grown" stands for gemstones created in a lab rather than mined from the earth. "Leo" comes from the Leo constellation, a symbol of strength, confidence and creativity. We want every piece to feel like that: bold, brilliant and made with a clear conscience.
