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 Toi et Moi Necklaces

For the absolute purists who want premium luxury weight against the skin, our 18K white gold Toi et Moi necklaces are where it’s at. Because 18K gold contains a higher ratio of pure precious metal (75%), it has a richer, more substantial physical presence on your neckline. We couple this premium backdrop with magnificent stone pairings to create a breathtaking, liquid-like mirror shine that exudes prestige.

Why Choose an 18K White Gold Lab Diamond Toi et Moi Necklace?

Choosing 18K white gold means you are investing in an heirloom-grade composition that offers a noticeably heavy, prestigious feel against the skin. We craft these premium pieces using a specialized white gold alloy mixed with dense, high-purity precious metals, providing an ultra-bright canvas that maximizes true diamond fire and scintillation. To lock in a lifetime of tarnish resistance, our master jewelers apply a premium, thick coat of rhodium plating over the intricate setting. This elite standard offers uncompromised luxury and robust prong security for serious, high-carat lab grown diamond combinations.

How to Style and Layer Your 18K White Gold Two-Stone Diamond Pendant

This level of luxury demands to be noticed, but it excels at looking completely effortless. Let a high-impact masterpiece like our 4 ctw Duo Drop Heart and Round Lab Grown Diamond Necklace in 18K White Gold or our striking 18K White Gold 2ctw Toi et Moi Emerald and Pear Lab Grown Diamond Necklace rest against bare skin inside a plunging neckline or paired with a sleek silk slip dress as your undisputed focal point. For high-end luxury styling that works from day to night, frame the twin-stone pendant with a structural blazer and team it up with our matching 18K white gold lab diamond drop earrings for a fully intentional, high-wattage look.

FAQs

What makes 18K white gold more premium than 14K white gold?

18K white gold contains 75% pure gold and only 25% alloy metals, compared to 58.3% pure gold in 14K. This gives your Toi et Moi necklace a much higher gold purity, a noticeably heavier and more luxurious weight against your skin, and an elite prestige factor coveted by high-end jewelry collectors.

Does 18K white gold still need rhodium plating?

Yes. Because it features a massive 75% pure yellow gold content, unplated 18K white gold has a distinct, warm, buttery white tint (often called raw white gold). We finish every piece with a heavy coat of ultra-bright rhodium plating to achieve that liquid-mirror shine, but when the plating eventually wears down, the underlying metal will show a slightly richer, warmer undertone than 14K.

Is 18K white gold hypoallergenic?

While it is much better for sensitive skin than lower-karat golds because it contains far fewer base metal alloys. If you prefer absolutely hypoallergenic setting, our pure Platinum Toi et Moi pieces are your safest option.

How do I maintain the premium luster of my 18K white gold Toi et Moi necklace?

Keep it away from harsh household chemicals, especially chlorine (like in swimming pools or hot tubs), which can structurally stress high-karat gold alloys. Store your Toi et Moi necklace in its original jewelry box when not in use to prevent it from rubbing against other jewelry.
