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 Solitaire Necklaces

For the absolute purists who want that heavy, top-tier luxury feel, our 18K white gold solitaire necklaces are where it’s at. Because 18K gold contains a higher percentage of pure gold, it has a richer, more substantial weight on your neckline. We couple this premium metal with a single, hand-selected lab diamond to create a breathtaking, liquid-like shine that completely commands the room.

We craft these pieces using a premium white gold alloy that provides a flawless, bright backdrop for maximum diamond fire. It’s uncompromised, sustainable luxury for the collector who wants maximum prestige and a chain that feels truly elite.

How to Style an 18K White Gold Solitaire Necklace

This level of luxury demands to be noticed, but it never feels like it's trying too hard. Let an 18K white gold solitaire rest against an open neckline or a sleek silk slip as your undisputed focal point. To lock in a look that feels completely intentional from head to toe, team it up with our matching 18K white gold lab diamond drop earrings.

FAQs

What is the difference between 14K and 18K white gold?

18K white gold contains a higher percentage of pure gold (75% versus 58.5% in 14K). This gives the necklace a richer, weightier feel against your skin, carrying that top-tier, heirloom prestige that purists love.

Does 18K white gold need to be plated?

Yes, just like 14K, 18K white gold gets its flawless, liquid-mirror finish from a premium rhodium plating. Because 18K has more natural yellow gold in its core, the warm undertones may emerge slightly sooner than 14K, but a routine rhodium refresh keeps it bright white forever.

Is 18K white gold too soft for a daily necklace?

Not at all. While 18K is slightly softer than 14K due to the higher gold content, it is still exceptionally strong and securely holds your diamond centerpiece. For a solitaire necklace that sits safely on your neckline, 18K offers plenty of durability alongside its luxurious weight.

Does 18K white gold necklace setting make a diamond look brighter?

The ultra-bright white metal framework of 18K white gold blends seamlessly with a colorless or near-colorless lab diamond. It ensures there are no warm metal reflections bouncing into the stone, allowing the true, icy fire of the diamond to take center stage.

How should I store my 18K white gold solitaire diamond necklace?

Because 18K gold is a premium, precious metal, store it in its original Lucenjuri jewelry box or a separate compartment in your jewelry box. This prevents harder gemstones or other pieces from scratching the rich, high-luster gold finish.
