Here you can see how Blue Nile and Helzberg Diamonds match up head-to-head in a battle for the Best Lab Grown Diamond Stores in 2026.
Blue Nile is a top choice for anyone looking to buy lab grown diamonds, offering over 52,000 options across the site's selection. Whether you want to design your own engagement ring online or visit an in-person showroom for expert guidance, Blue Nile makes the process easy with 360-degree diamond previews, free returns, and a price match guarantee. With strong customer reviews and an "A+" BBB rating, it's a trusted jeweler for high-quality lab grown diamonds at competitive prices.
Helzberg has been a trusted jeweler since 1915, offering both in-store and online shopping for diamonds and fine jewelry. However, its selection of lab grown diamonds is much smaller than competitors, its website can be tricky to navigate, and customer service reviews are disappointing. While Helzberg maintains an "A+" BBB rating which may make it worth a look, its limited selection, short warranty, and poor customer feedback lead us to give it a lower rating as a place to buy lab grown diamonds.
Diamonds might be a girl's best friend - and, honestly, guys aren't immune either - but the sticker shock is what keeps most people from pocketing those glittering stones. Say "diamond" and you can practically see the dollar signs piling up. The upside is that there are truly more affordable ways to get the real sparkle, and we're not talking about fakes or cubic zirconia lookalikes. Lab-grown diamonds, for example, are chemically identical to mined stones and often cost far less, which means you can choose a stunning piece without blowing your budget.
We're talking lab-grown diamonds that offer the same brilliance as stones pulled from the earth - just at a fraction of the price. In short, a lab-grown diamond is a real diamond. The Gemological Institute of America confirms that lab-grown and natural diamonds match in hardness, durability, and clarity, and both are certified as diamonds. Because they're created in controlled settings, you can count on consistent quality and a wide range of sizes and shapes.
Lab‑grown, or man‑made, diamonds are produced in controlled labs using methods like high pressure high temperature (HPHT) to grow crystals that mirror earth‑mined stones in both chemistry and physical properties. To the naked eye they're indistinguishable - the sparkle and structure are the same - and any subtle differences only show up under serious magnification. Reputable grading labs even assess them by the same 4Cs as natural diamonds, making side‑by‑side comparison straightforward for buyers.
Natural diamonds form over millions of years deep in the earth, where intense pressure leaves trace nitrogen in the crystal. Lab-grown stones recreate those conditions in a controlled chamber and finish in a matter of months. Because they don't require risky mining, they're generally safer to produce, cost less, and can be the more ethical - sometimes even carbon-neutral - option. On average, you're paying about 30-50% less for a lab-grown diamond with the same cut and quality, so it's easier to choose a larger, certified stone without overspending. Both lab-grown and natural diamonds are real diamonds with the same physical and chemical properties, so the choice often comes down to origin, budget, and personal values.
Whether you're shopping for an engagement ring, treating yourself to something sparkly, or hoping to start a future heirloom, the real priority is finding a trustworthy source for quality lab-grown diamonds. A reputable seller will be transparent about cut, color, clarity, and certification - so you know exactly what you're getting. Taking a little time to check reviews, compare options, and understand return policies can make the whole experience feel as special as the stone itself.
