A World-Class Diamond Collection

Icestore offers one of the largest curated selections of GIA and IGI-certified lab-grown diamonds online, featuring:



A selection of diamonds from Icestore including colorless GIA certified loose diamonds, lab-grown fancy color diamonds in vivid blue, vivid green and vivid pink along with a selection of GIA certified natural yellow diamonds.


Every diamond on Icestore.com is displayed with high-resolution photography and 360° ultra-HD video, allowing clients to explore each stone in extraordinary detail before purchase.


Exceptional Value

Icestore’s direct-to-client model eliminates traditional retail markups, offering prices up to 50% lower than other major online jewelers and as much as 80% less than traditional retail stores — without compromising on quality or certification.


Each purchase includes risk-free 30-day returns, secure worldwide shipping, and lifetime support from our expert team.


Ethical & Eco-Conscious

All lab-grown diamonds at Icestore are eco-friendly, conflict-free, and grown using advanced methods that replicate nature’s brilliance with sustainability in mind.


Here are some of the other top sellers of diamonds online:


Blue Nile

Blue Nile remains a respected online jeweler offering a large selection of certified lab-grown diamonds. Their clean interface and established reputation make them a reliable choice for buyers seeking a straightforward shopping experience. Or so we thought. A quick glance at their BBB record tells a different story.


James Allen

James Allen provides detailed 360° viewing for diamonds and offers a range of customizable settings. Their platform is designed for those who appreciate visual shopping and a wide inventory. Jamesallen seems to be doing better at least than bluenile.

Jamesallen's BBB https://www.bbb.org/us/md/frederick/profile/jewelry-stores/jamesallencom-0011-22011065/customer-reviews shows a solid history and following through on their committments but 63 complaints over the last 3 years is a sign that there are some cracks in the system.


It’s important for consumers to know that Blue Nile and James Allen are both owned by Signet Jewelers, the same parent company that also operates Kay, Zales, and Jared. While the brands are marketed separately to create the appearance of more choice in the marketplace, they ultimately share the same corporate ownership, strategic direction and massive corporate overhead. This means that what may appear as competition between brands is, in fact, part of a consolidated retail network.


Brilliant Earth

Brilliant Earth is known for its focus on sustainability and ethical sourcing. Their selection includes lab-grown diamonds as well as recycled precious metals for environmentally minded shoppers. This company has some solid reviews but scratching the surface reveals 290 complaints over the last 3 years. https://www.bbb.org/us/ca/san-francisco/profile/diamond/brilliant-earth-llc-1116-154721/customer-reviews


Buyers should also be aware that Brilliant Earth’s pricing is often significantly higher than comparable stones offered elsewhere. While the brand positions itself around sustainability and ethical sourcing, — admirable goals but a claim that has been challanged and squashed under threat of legal action, — its markups can be substantial, sometimes reaching 30–60% above equivalent certified lab-grown diamonds available through other reputable jewelers. For shoppers focused on value and transparency, understanding these market dynamics helps ensure they make an informed decision.


Other Notable Options


  • With Clarity – Offers lab-grown diamonds and custom engagement rings.

  • Ritani – Provides a hybrid experience with online and in-store viewing options.

  • Clean Origin – Focuses solely on lab-grown diamonds with accessible pricing.
