The Gift of Lab Grown Diamonds: La Joya

Providing the beauty only real diamonds can offer while selling them at a fraction of the cost of mined gems, Ja Joya offers lab grown diamonds set in a wide variety of attractive pieces. Ja Joya focuses on giftable jewelry that can be worn daily, though there are also pieces intended for special occasions. The diamonds are IGI or GIA certified, shipping is insured in the U.S., and returns are straightforward within 30 days for peace of mind.

While there are a growing share of new players on the block, La Joya is a third generation family business focused on making diamond jewelry accessible and they have their U.S. distribution based in New Jersey. Given their decades of experience, it isn't surprising that they offer a broad catalog of beautiful pieces. Engagement rings and wedding rings might bring the most first time buyers, but people come back for earrings, bracelets, rings, and necklaces. You can also find fashion-forward designs like toi et moi and tennis necklaces. It should be noted that items are shipped strictly within the United States.

Earrings and bracelets

There is a wide variety of diamond earrings to choose from including classic round stud pairs, martini and bezel settings, halos, huggies, hoops, and some cluster or drop styles. Stud pairs are matched for color, clarity, and cut, so you get a proper matching sparkle. Bracelets designs include the classic tennis bracelet, bolo, and bangles with carat weights that range from delicate daily wear to very extra. The adjustable slider on bolos gives an easy fit for gifting. Tennis bracelets show prong, channel, and two prong styles so you can pick more sparkle or more security.

Certification, metal, and build details

La Joya states that its diamonds are certified by IGI or GIA. That is a strong box to check for lab grown buyers since you want independent grading. A quick 2025 note. GIA is shifting how it reports on lab grown diamonds, moving from traditional color and clarity grades to a new Quality Assessment with descriptive terms beginning October 1, so your GIA paperwork may look different than older reports. IGI has said it will keep grading lab grown using the familiar 4Cs scale. Metals are mostly 10k and 14k gold along with some 18k on select pieces and sterling silver in fashion items. Stud settings like martini, basket, and bezel plus secure butterfly backs are common. These are the right building blocks for daily wear.

Policies and peace of mind

Shipping is complimentary and insured via UPS or FedEx, with signatures required on some FedEx items. Certificate cards are included, which is useful if you plan to insure the piece. Returns are 30 days from shipment (item must be in original condition). You can return a piece twice within the window, though a second return may carry a restocking fee or be limited to store credit. The warranty window is a one year warranty on manufacturing defects, plus the option to buy a Jewelers Mutual care plan and a published lost jewelry replacement discount. Be sure to take the time to read both the warranty page and the FAQ so you know which benefits apply.

Lab grown vs natural, the quick reality check

Lab grown diamonds are real diamonds. They share the same crystal structure and optical performance as mined stones, and most people cannot tell them apart without specialized equipment. The main trade off is long term resale. Wholesale prices for lab grown have fallen hard as supply scaled up, which is great for getting a larger look today, but it means you should buy for wear rather than future trade in value. The industry is also evolving on grading standards, which is why that GIA update matters. If you are set on a pedigree heavy, heirloom strategy, natural may still be your match. If you want sparkle and size for everyday joy, lab grown wins.

How La Joya stacks up

For policies, La Joya’s 30 day return window aligns with names like Brilliant Earth and James Allen, though Clean Origin offers about double that time. Brilliant Earth also advertises a free lifetime manufacturing warranty, which some shoppers value on principle. Selection wise, Blue Nile is a well known benchmark for lab tennis bracelets and studs, with deep inventories and many carat choices. Where La Joya differentiates is the combination of certification, insured shipping, a direct to consumer model, and a care plan with a clear lost item replacement discount. If you want popular silhouettes without chasing customization, it is a straightforward place to shop.

Buying advice for earrings and bracelets at La Joya

For studs, you should prioritize the cut quality and matched pairs. A clean martini or bezel setting in 14k will sit neatly and wear comfortably. For hoops and huggies, decide if you want more sparkle or more security. Channel set hoops hide metal between stones (which gives a sleek line). For tennis bracelets, be sure to measure at home to get the drape and clasp comfort you want. A two-prong or three-prong style gives a brighter look, while channel or bezel styles trade sparkle for daily toughness. If you are curious about everyday pieces beyond earrings and bracelets, look at their solitaire and tennis necklaces in 10k and 14k gold plus a handful of sterling silver fashion pieces. They round out a simple, matched set nicely.

Vetted Verdict

With so many years of history and such an established customer base, La Joya is one of the stand-out online jewelers that we would feel comfortable ordering from. You get considerably more for your money, which is why the pieces look fuller and why there are so many options for any given budget. Certification is standard, shipping is insured, and returns are easy to handle should you decide you want to go with something different. If you are shopping for everyday sparkle that you can gift without stress, La Joya is a safe bet.
