12FIFTEEN is part of the Forever Companies brand family, which includes Diamond Nexus and Forever Artisans. The common thread? None of the brands use mined stones in any of their jewelry, letting you shop freely knowing that your purchase will always be conflict-free.

Small-ish selection of jewelry beyond engagement rings

The selection of lab-created diamond jewelry at 12FIFTEEN is small, if you're just looking at pieces beyond engagement rings. At the time of our most recent visit, the online store had just under 200 options, but some of them were chains or other items that didn't have diamonds. Choices included everything from simple necklaces and earrings under $300 to tennis necklaces and bracelets in the $6,000 to $9,500 range.

Generous selection of loose lab-created diamonds

But, when you jump to loose stones and engagement settings, your options expand exponentially. Of course, the selection will be different from one day to the next (because people are creating the pieces of their dreams), but you'll probably find over 17,000 loose lab-grown diamonds at 12FIFTEEN at any given time. We saw a couple dozen gems under $300 (mostly under a half-carat), and a little over a dozen in the $20,000+ category. The jeweler's highest-end lab-created diamond during our visit was a 11.12 ct round stone, ideal cut, E color and VS1 clarity, priced at $83,630.

Filter your choices

It's easy to find all of the man-made stones sold by 12FIFTEEN. Just indicate if you have a preferred shape, carat size, price range, color, clarity, or cut quality, and you'll be good to go. You can also check boxes that will display stones that are marked down, available for quick shipping, or that are designated as "Hearts & Arrows'' (a near-perfect round brilliant lab diamond that radiates a hearts-and-arrows pattern when seen through a professional scope).

Free design services for a hand-crafted piece of jewelry

Whether shopping for an engagement ring or some other type of jewelry, you can use 12FIFTEEN's design services to create a one-of-a-kind piece. Connect with one of their consultations with anything you have in mind - photos, drawings, even a sketch on a cocktail napkin - and within 72 hours you'll get a CAD file with the preliminary design. Once you've suggested any edits you'd like and approved the final design, your custom lab-grown diamond jewelry will be made by hand in Milwaukee.

No complaints here

Not only does 12FIFTEEN have an "A+" rating and accreditation from the Better Business Bureau, there were also no complaints filed there over the last three years. Not bad for a company that's been around for a decade. There are also about 100 reviews on the 12FIFTEEN site you can browse, looking at customer photos and comments (which are, unsurprisingly, all positive). While we'd like to see a little more feedback in other places - Trustpilot, for example, only had one review when last we checked - this retailer is plenty active on its social media channels, so we have no concerns that 12FIFTEEN is anything other than a solid choice for buying lab-grown diamonds.

Free shipping and 30-day returns

How about shipping and returns? All orders over $100 ship free here. 12FIFTEEN gives you the standard 30-day period starting from the date your order is delivered. Just make sure your diamond or jewelry is in perfect, unused condition with all protective materials in place, and that you send it back with all original packaging and paperwork or else you'll be charged a $75 fee.

Worth your time to take a look

12FIFTEEN easily ranks as an above-average option for buying jewelry made with lab-grown diamonds. The selection of diamonds is good (but doesn't compete with rivals' inventories of 130,000+ stones), there's a nice array of non-engagement ring pieces to consider, and by all appearances 12FIFTEEN's clients love what they get. Although there are a few stores we'd shop first, there's no reason not to go with 12FIFTEEN if something sparkly catches your eye there.

Where Can You Find the Best Lab Grown Diamonds?

Lab-grown diamonds, also known as synthetic or cultured diamonds, are man-made gemstones that are created in a laboratory environment using advanced technological processes that mimic the natural conditions under which diamonds form in the earth's mantle.

Sounds pretty technical, but the amazing thing is that these diamonds are essentially identical in chemical, physical, and optical properties to natural diamonds mined from the earth. They are also graded on the same 4Cs scale used for natural diamonds, which stands for cut, clarity, color, and carat weight. All of the same sparkle factor? Yes, please!

Lab Grown Diamond Store FAQ

Lab-created diamonds are gemstones that are grown in a laboratory instead of being mined from the earth. They have the same chemical, physical, and optical properties as natural diamonds.
Yes! They have the same characteristics as natural diamonds and can only be distinguished from natural diamonds using specialized equipment. Your lucky recipient - or your friends at girls' night - will never know.
Lab-created diamonds are usually considered more ethical than natural diamonds because they are not associated with environmental destruction or human rights abuses. However, the environmental impact of producing lab-created diamonds and the working conditions of lab workers may also be factors to consider.
Yes, lab-created diamonds are typically less expensive than natural diamonds of the same quality and size. This is because the cost of producing lab-created diamonds is lower than mining natural diamonds.
Unfortunately, no. These man-made gemstones have lower resale value than natural diamonds because they are not as rare. However, this may change as lab-created diamonds become more popular and widely accepted in the jewelry industry.
Lab-created diamonds are made using two different methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). HPHT mimics the natural diamond formation process by subjecting a small diamond seed to high temperature and pressure. CVD uses a gas mixture to deposit carbon atoms onto a diamond seed, which eventually grows into a diamond.
100%. They have the same hardness, toughness, and resistance to scratching and chipping.
Absolutely! They are a popular and ethical alternative to natural diamonds and offer the same beauty and durability. It's a great way to get a stunning ring at a much lower price than you'd spend for jewelry with natural gemstones. And unless you tell her (or him), your intended will never know the difference.

Continued from above...

Better yet, lab-grown diamonds are generally less expensive than natural stones of the same size and quality. And, if you've ever been concerned by the idea of "blood diamonds" , lab-grown stones are perfect for you: they don't involve the environmentally damaging (and often unethical) practices associated with natural diamond mining.

However, lab-grown diamonds have a few small drawbacks. One major concern is that they may not hold their value over time as well as natural diamonds, since they aren't as rare or unique. Additionally, some people may prefer the idea of owning a natural diamond as a symbol of their love or commitment - even if lab-created stones are undetectable as such to the average person's eye.

When you realize that some jewelers offering lab-grown diamonds have an inventory of over 100,000 stones to choose from, you might feel a little overwhelmed. Take a deep breath, try to enjoy the process a little, and use these ideas to make your shopping easier:

  • Filters. The quickest way to narrow down thousands upon thousands of choices is through smart use of filters. Most sites will let you select your preferred stone shape (round, oval, heart, pear) and set a price range. If you already know what clarity or color parameters you'll accept, indicate those as well.
  • Consultations. It can be confusing to create an engagement ring or other custom piece of jewelry, or even to understand the ins and outs of lab-grown diamonds. Some retailers offer consultations, either virtually via video call or in-person at a location near you. Take advantage of this service if you're feeling nervous or you just want an extra set of eyes to look over your design or purchase.
  • Customer benefits. Know what to expect with any jewelry store you're considering. How long will you have to make a return if the "Will you marry me?" doesn't get a "yes" answer, or if those earrings just don't look as good in person as they did online? What's the warranty coverage? Is there a price match guarantee if you find a similar lab-created diamond somewhere else?
  • Reputation. Other shoppers' feedback is a great way to gauge if a retailer of lab-grown diamond jewelry is doing a good job. Check out customer photos of the rings, bracelets, and so on: how do they look in the "real world" ? Is there any pattern of complaints? Has the store received a favorable grade from the Better Business Bureau?

Shopping for jewelry made with lab-grown diamonds can be an exhilarating experience, and Top Consumer Reviews has evaluated and ranked today's most popular retailers to give you an advantage as you browse. We hope this information helps take the edge off any nervousness you might be feeling, so that you can find - or create - the perfect piece of jewelry for that proposal, anniversary, or "just because" moment.
