We specialize in lab-grown diamonds — a modern, ethical alternative to mined diamonds. Grown using advanced technology, our diamonds are chemically and visually identical to natural ones, offering the same brilliance and hardness without the environmental or ethical concerns of traditional mining.
At GUYAL, we create sustainable fine jewelry that blends luxury, ethics, and craftsmanship. Our mission is to offer elegant, responsibly sourced pieces using the finest materials — including lab-grown diamonds, vermeil, rhodium plating, and 18k gold — so you can wear your values as confidently as your style.
Many of our designs feature a rhodium-plated finish, a rare precious metal from the platinum family. Rhodium enhances shine, resists tarnish, and is naturally hypoallergenic — making it an ideal choice for high-shine silver jewelry that’s gentle on sensitive skin.
Our vermeil jewelry is crafted from solid 925 sterling silver and coated in thick layers of 18k gold, making it more durable and luxurious than traditional gold-plated pieces. Vermeil combines the beauty of real gold with the strength of sterling silver, offering long-lasting elegance at a more accessible price.
