This necklace and company are wonderful! I asked for a custom length made and it was perfect! The stones are clean and sparkly! Love them! Very quick shipping. Christine in customer service is the best; great communication. I would trust no other company for lab created diamonds

Absolutely Stunning Necklace & Exceptional Service! 💛✨
I’m absolutely in love with my Starry Charm necklace! 😍 It’s even more beautiful in person, and the sparkle is incredible. I ordered the 0.50ct version and was so pleasantly surprised that mine totaled 0.63ct! I upgraded it to 18k gold and the 18K yellow gold is absolutely gorgeous too. A special thank you to Emma, who made the entire experience wonderful. She was incredibly kind, attentive, and helpful throughout the whole process. I’m so happy with both the necklace and the amazing customer service that I’ve already ordered another piece! 💛✨

super sparkly!
Among all the jewelry companies I contacted while looking for a necklace, Lucenjuri stood out for its exceptional and sincere customer service. While many other companies filled my inbox with promotional and high-pressure sales emails after I inquired or registered, your team never did that at all.When the necklace arrived, I was absolutely amazed—both the diamond and the chain are truly, incredibly sparkly! I previously ordered a lab-grown diamond necklace from a well-known company with a store in Beverly Hills, but it didn't impress me at all, and I ended up returning it. Buying jewelry online made me feel a bit anxious at first, but any doubts I had vanished the moment I opened your package.Thank you so much, Nicole and Christine, for your kind and thoughtful replies. You made my experience truly unforgettable.

Great experience - Please do not hesitate to buy!!
I was skeptical to place an order for an expensive piece of jewelry from an online company - especially one that I had never heard of before - but let me just say, working with Lucenjuri and our lovely consultant, Christine was a pleasure from beginning to end. She guided me through stone selection and kept me informed through the entire process from fabrication to shipping to follow up. The necklace was even better than expected and the price was better than competitors who were selling inferior stones. They earned my trust and I would purchase from them again without a doubt.

Sparkles so much!
I ordered the sparkling cluster diamond necklace and can’t believe how much it sparkles. For me, it is a statement piece, good for special occasions. Definitely a wonderful gift for yourself or a loved one.

Top notch
I purchased the 1 Carat Bezel Solitaire Round Diamond Necklace in Platinum for myself. I chose platinum because I am sensitive to all other metals and because its very strong. I didn't know the company before this purchase and was really impressed with the level of communication during the process of making the necklace, all the way up to shipping. When I finally received the item, it was stunning. The bezel setting makes the diamond appear bigger in my opinion, so it is very impressive. I also bought a set of diamond stud earrings and the combined packaging both items were sent in was really beautiful and premium. If you are hesitant, just do it!

Very positive experience with Lucenjuri
My necklace arrived on time, progress was well communicated throughout the entire process and the end product was perfect! Great quality and beautiful diamonds! I have already referred someone to Lucenjuri for an engagement ring. With declining customer service everywhere - my experience with Lucenjuri was above and beyond!

3ct, toi et moi emerald and pear necklace
The diamonds are absolutely stunning and with 3ct the chain was automatically upgraded to 1.1mm thickness. Amazing customer service communication as well - thank you Christine - and fast delivery. IGI certificates are included.

Rose gold bezel set- excellence in a box
I searched in stores and online for the perfect piece- rose gold lab grown bezel set pear shaped pendant. This is what I’ve searched high and low for. I was a little worried it wouldn’t arrive quickly but I received it a week ahead of schedule. Very happy with my purchase!

Exceeded my expectations!
My husband gifted me an emerald diamond pendant necklace for our 15 year anniversary. It's a beautiful necklace that I wear almost everyday now. Received many compliments on it within just days of wearing it. I will definitely be ordering more jewelry from Lucenjuri! Highly recommended.

18K White Gold Lab Grown Diamond Pendant Necklaces

For the absolute purists who want that heavy, top-tier luxury feel, 18K white gold is where it’s at. Because it has a higher percentage of pure gold, it feels richer and more substantial against your skin. Paired with our hand-selected lab diamonds, it creates this insane, liquid-like shine that completely commands the room.

We craft these pieces in our artisan studio using a premium white gold alloy that acts as a high-wattage backdrop for maximum diamond fire. It’s uncompromised luxury for the modern collector who wants premium weight without the ethical baggage.

How to Style 18K White Gold Diamond Pendants

This kind of luster demands to be seen. Let an 18K white gold halo pendant do all the talking by styling it against an open neckline or a sleek silk slip. It’s an instant outfit elevator. To lock in a look that feels completely intentional, pair it with our 18K white gold lab diamond drop earrings. It transitions effortlessly from a high-stakes meeting to late-night drinks.

Why Choose the Lucenjuri 18K White Gold Collection

When you shop your 18K white gold lab grown diamond pendant necklaces at Lucenjuri, you are investing in heirloom-level quality without the legacy retail markup. We don’t cut corners. You get certified, hyper-brilliant lab-created diamonds set into secure, master-crafted metalwork. It’s sustainable, high-end fine jewelry that looks elite and feels entirely right.

FAQs

Is 18K white gold better than 14K white gold for a pendant?

"Better" just means what you value more. 18K white gold has more pure gold in it (75% vs 58.5%), so it feels heavier, more luxurious, and carries more prestige. On the flip side, 14K white gold offers incredible everyday durability and a more approachable investment point. For a keepsake piece that sits safely on your neckline, 18K is the ultimate move if you want that heavy, top-tier heirloom feel.

Does 18K white gold contain nickel?

Yes, most white gold alloys use a tiny bit of nickel to bleach the yellow gold white. Because 18K has less alloy space, it bothers sensitive skin less than 14K. But if you have a serious, full-blown nickel allergy, skip white gold entirely and go with our naturally pure, hypoallergenic platinum.

Why does my 18K white gold pendant look so bright?

Because we don't skimp on the finish. We coat all our 18K white gold pendants in premium rhodium—a rare precious metal from the platinum family. It gives the piece an ultra-reflective, liquid-like mirror shine that makes your lab diamond look even larger and brighter.

What diamond shapes look best in an 18K white gold setting?

Honestly, round brilliant, oval, and pear shapes look insane in 18K white gold. Because the metal is so bright and colorless, it blends seamlessly with the diamond’s edges. This creates a massive illusion of continuous light without any yellow metal tints showing through the stone.

How should I store my 18K white gold necklace so it doesn't tangle?

Never just throw it into a drawer. The trick is to fasten the clasp and leave about an inch of the chain hanging outside of a small zip bag or soft pouch. If the two ends can’t meet, the chain physically cannot knot itself into a total nightmare.
