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 Yellow Gold Lab Grown Diamond Toi et Moi Necklaces

If you want to go all out on deep, rich, honeyed opulence, an 18K yellow gold Toi et Moi necklace is the ultimate flex. Packing a high gold content, it has an unmistakable, regal warmth that frames contrasting diamond shapes beautifully. The heavy, premium feel of our fluid chains against your skin lets you know instantly that this is a top-tier, substantial piece designed for the modern collector.

Why Choose an 18K Yellow Gold Lab-Created Diamond Toi et Moi Necklace?

Opting for 18K yellow gold gives your jewelry that authentic, high-purity, old-world gold look that cannot be replicated by lower karats. Because 18K gold is naturally softer due to its high precious metal purity, our master jewelers specifically engineer these luxury settings with reinforced structural undergalleries and thickened, substantial prongs. This expert craftsmanship ensures that large, statement-scale diamond pairs stay completely locked down and protected, offering an eco-friendly investment piece that holds its value and premium beauty for generations.

How to Style Your 18K Yellow Gold Two-Stone Lab Diamond Necklace

An 18K yellow gold two-stone necklace carries a massive artistic presence all by itself, making it a spectacular standalone hero piece. Let the striking geometry of our 18K Yellow Gold 2ctw Toi et Moi Emerald and Pear Lab Grown Diamond Necklace or our showstopping 18K Yellow Gold 3ctw Toi et Moi Oval and Pear Lab Grown Diamond Necklace rest elegantly against bare skin paired with an off-the-shoulder sweater or a silk top to let that rich gold really sing. For an upscale, ultra-cohesive editorial style, carry that deep golden-hour warmth through your entire look by matching it with our solid 18K yellow gold lab diamond tennis bracelets.

FAQs

Does 18K yellow gold tarnish or change color?

No. Solid 18K yellow gold will never tarnish, rust, or turn your skin green. Its deep, regal color is completely permanent and runs solid all the way through the metal. It requires absolutely no replating or chemical dips—just a simple soapy water wash to keep it looking pristine forever.

What diamond grades are paired with 18K yellow gold?

We use top-tier, colorless lab diamonds. The rich, deep golden warmth of an 18K yellow gold Toi et Moi necklace setting acts as a stunning frame, emphasizing the stark, bright clarity and intense fire of our sustainably grown stones.

Is 18K yellow gold suitable for sensitive skin?

Yes, exceptionally so. Because 18K yellow gold is 75% pure gold, it contains a very minimal percentage of base metal alloys. This makes it highly biocompatible and an excellent, soothing choice for anyone whose skin reacts negatively to lower-purity gold alloys.
