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.

Platinum Lab Grown Diamond Solitaire Necklaces

Welcome to the absolute peak of fine jewelry engineering. Our platinum lab grown diamond solitaire necklaces are the ultimate choice for true jewelry purists who want zero distractions. Platinum is naturally pure white and thirty times rarer than gold. Because it never changes color or requires replating, it holds a single, exceptional lab diamond in an ice-bright grip that maximizes its true colorlessness and clarity.

Choosing a Lucenjuri platinum solitaire necklace is an investment in absolute longevity. Its heavy, substantial weight offers a grounding, luxurious feel on the neckline, while our premium chain ensures your conscious centerpiece stays flawlessly secure for a lifetime.

How to Style a Platinum Solitaire Necklace

Platinum is sleek, clean, and structural, so we like to keep the styling just as intentional. Pair a platinum round brilliant solitaire necklace with minimalist tailoring or sharp, structural silhouettes. Let that cool, bright metal do the heavy lifting, or pair it with our certified platinum lab diamond martini studs for an echo of unrivaled, high-end brilliance.

Shop Premium Platinum Lab Diamond Solitaire Necklaces at Lucenjuri

When you shop your platinum lab grown diamond solitaire necklace at Lucenjuri, you’re choosing the ultimate standard of sustainable luxury. No plating, no tarnishing, and absolutely zero compromises. We pair this elite, secure metal with the finest certified lab-created diamonds to give you a masterpiece that stands the test of time.

FAQs

Why should I choose platinum over white gold?

Platinum is the absolute pinnacle of fine jewelry. It is naturally pure white (so it never needs to be replated), completely hypoallergenic, and significantly denser than gold, giving your necklace a premium, substantial weight that feels incredibly luxurious.

Does platinum scratch or change color?

Platinum never changes color or turns yellow because it’s naturally white to its core. While it can pick up tiny surface scratches over time, the metal isn't actually lost—it just shifts, creating a beautiful, velvety finish known as a patina. You can easily have it polished back to a high-shine finish anytime.

Is platinum completely hypoallergenic?

Yes. Because our platinum solitaire necklaces are 95% pure precious metal, they are entirely hypoallergenic. If you have highly sensitive skin or a nickel allergy that makes wearing certain gold alloys difficult, platinum is the absolute safest choice.

How secure is a diamond in a platinum necklace setting?

Platinum is incredibly dense and malleable, meaning it doesn't thin out or become brittle over time. Prongs made of platinum hold a lab grown diamond in a lifetime, ultra-secure grip, making it the ultimate choice for protecting your centerpiece stone.

Why does a platinum necklace feel different on the neckline?

Platinum is about 60% heavier than 14K gold. When you put on a Lucenjuri platinum solitaire necklace, you will instantly notice a grounding, weighted, top-tier feel against your skin that screams premium, uncompromised luxury.
