Collection: Lab Grown Diamonds

King Jewelers carries a dedicated lab grown diamond collection in Nashville, with over 100 pieces built almost entirely around our in-house Ella Rose line. The collection spans engagement rings, wedding bands, earrings, necklaces, and bracelets.

Pieces are set in yellow gold, white gold, and platinum, with many stones IGI certified for authenticity and quality assurance. Prices start around $1,200 for an everyday pendant or stud earrings and reach up to nearly $20,000 for statement pieces like large tennis bracelets and multi-carat engagement rings, giving lab grown shoppers a wide range to work with, often at a lower price point than comparable natural diamonds.

Shop the full lab grown collection online with free shipping on qualifying U.S. orders over $500, or visit our Green Hills showroom in Nashville to see the stones in person and get guidance from our team. Since 1912, we've helped Nashville shoppers navigate diamond choices, and we back every lab grown piece with the same appraisal and service support as our natural diamond jewelry.

Lab grown diamonds are chemically, physically, and optically identical to mined diamonds, so choosing one comes down to the same fundamentals as any diamond purchase, with a few extra things worth knowing about the category itself.

Understand what makes them different (and what doesn't)
Lab grown diamonds are grown in controlled lab environments using methods like CVD or HPHT, rather than forming over billions of years underground, but the result is a real diamond with the same crystal structure. The FTC officially recognizes them as diamonds, and no jeweler or gemologist can tell a lab grown stone from a mined one by eye alone. The only difference that matters practically is origin, and origin is disclosed on the certificate.

Judge them with the same 4Cs
Cut, color, clarity, and carat weight apply identically to lab grown and natural diamonds, using the same GIA scales. Cut still matters most for brilliance and sparkle, since it's the one factor driven by craftsmanship rather than the stone's origin. One practical upside: because lab growing happens in a controlled environment, lab grown stones can often achieve higher clarity grades more consistently than mined diamonds, and cutters have more flexibility to prioritize an ideal cut without worrying about preserving carat weight from an expensive rough stone.

Always buy certified
Get a grading report from a reputable independent lab, GIA or IGI are the two most trusted, which documents the 4Cs and confirms the stone's lab grown origin. Certified lab grown diamonds also carry a microscopic laser inscription on the girdle confirming their origin and report number, invisible to the naked eye but verifiable under a loupe, and matchable against the official certificate.

Expect meaningful savings
Lab grown diamonds typically run 30-50% less than a natural diamond of the same size and quality, which means your budget can go further, whether that's a larger center stone, a higher clarity or color grade, or a bit of both. This is one of the biggest reasons lab grown has become the majority choice for engagement ring center stones in recent years.

Know the trade-off
The one thing lab grown diamonds don't offer is the rarity and long-term resale value associated with natural stones. If that history and scarcity matters to you, natural diamonds still hold that appeal; if you'd rather prioritize size and quality per dollar, lab grown is hard to beat on pure value.

Since certification and cut quality matter more than origin once you've decided which type you want, the best approach is comparing certified stones side by side in person, ideally with a jeweler who carries both natural and lab grown options so you can see the difference (or lack of one) for yourself before deciding.

King Jewelers' lab grown diamond selection is anchored almost entirely by Ella Rose, our own in-house line built specifically around lab grown stones across engagement rings, wedding bands, earrings, necklaces, and bracelets. Every piece is set in 14K or platinum with certified stones (including IGI-certified options), giving shoppers a dedicated, ground-up collection rather than a scattered assortment of lab grown pieces borrowed from natural-diamond lines.

Lab grown diamond jewelry at King Jewelers, anchored by our in-house Ella Rose collection, is backed by the same free lifetime manufacturing defect warranty as our natural diamond jewelry. Lab grown diamonds also qualify for our Diamond Upgrade Program, allowing you to trade in your stone for a different size, quality, or shape at any time, paying only the difference in value. Certified lab grown diamonds (IGI-graded) are supported by expert appraisal services for insurance purposes, and pieces include complimentary cleaning, polishing, and sizing. Standard 15-day return and exchange terms apply to unworn lab grown diamond jewelry in original condition.
