Absolutely. Lab grown diamonds are real diamonds in every sense — chemically, physically, and visually. They have the same brilliance, sparkle, and durability as natural diamonds, and only expert gemological labs can distinguish between them using advanced equipment.

Yes, lab created diamonds share the same chemical and physical properties as natural diamonds, so they test similarly using standard diamond testers. Some HPHT diamonds may occasionally test as moissanite due to device limitations, but CVD diamonds typically test just like natural ones. Leading labs like IGI and GIA use advanced methods to verify and certify each stone accurately.

All our solitaire diamonds are of the highest quality. We exclusively use D-E color diamonds — the top grade on the color scale — and VVS-VS clarity, highest standard. Each diamond is cut to an excellent grade to ensure maximum brilliance and sparkle. We also only select diamonds with no fluorescence, preserving their natural beauty under all lighting conditions. Every solitaire comes with an IGI certification and a unique laser-inscribed number on the diamond’s girdle for authenticity and peace of mind. With GiliBili, you’re choosing diamonds that are not only stunning, but also ethically grown and expertly crafted.

GiliBili offers a curated collection of modern fine jewelry, featuring lab grown diamonds across engagement rings, earrings, necklaces, and bracelets. From everyday sparkle to that once-in-a-lifetime lab grown diamonds engagement ring, each piece is designed to be ethically luxurious, effortlessly chic, and made for your story.

Our standard processing time is 10-12 business days before your jewelry ships out. That said, timing can vary slightly depending on the piece — especially for custom or made-to-order designs.

For full transparency, you’ll find estimated shipping dates listed on each product page. Still have questions? Just reach out — we’re always happy to help.
