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 Pendant Necklaces

Welcome to the absolute peak of fine jewelry engineering. Our platinum lab grown diamond pendant necklaces are the ultimate choice for true jewelry purists. Platinum is naturally hypoallergenic, and denser than gold. It’s a pure white metal that never changes color, meaning it holds our ethically grown diamonds in an ice-bright grip that makes them look as bright and clear as possible.

This is an investment in absolute longevity. Its heavy, premium weight feels amazing on your neckline, and its insane durability means your conscious centerpiece stays flawless for a lifetime.

How to Style Platinum Diamond Pendants

Platinum is sleek, clean, and structural, so we like to keep the styling just as intentional. Pair a platinum round brilliant solitaire pendant 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 studs for an echo of unrivaled, high-end brilliance.

Why Choose the Lucenjuri Platinum Collection

When you shop your platinum lab grown diamond pendant necklaces at Lucenjuri, you’re choosing the ultimate standard of sustainable luxury. No plating, no tarnishing, and absolutely zero compromises. We pair this elite 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?

Choose platinum if you want zero maintenance and ultimate purity. Platinum is naturally white, so it will never turn yellow or need to be replated. It’s also much heavier and completely hypoallergenic. White gold is lighter, but requires a re-dip down the line to stay bright.

Does platinum scratch easily?

Platinum doesn't actually lose metal when it gets scratched; the metal just shifts over, creating a soft, worn finish called a "patina." Jewelry purists love this look because it looks vintage and elite. But if you hate it, a quick polish at a jeweler brings back the mirror shine instantly.

Is a platinum pendant completely hypoallergenic?

Yes. Our platinum pendants are 95% pure, making them completely hypoallergenic and totally safe for anyone with severe nickel or metal allergies. If your skin breaks out or gets itchy from standard jewelry, platinum is your safe haven.

Why does a platinum setting make a diamond look better?

Because platinum is a true, pure white metal, it acts like a stealth setting. It doesn't reflect any yellow or warm undertones into the stone. This makes your lab grown diamond look incredibly colorless, icy, and bright from every single angle.

Is platinum secure enough to hold a large diamond?

It’s the most secure metal on earth. Platinum is incredibly dense and malleable, meaning its prongs bend securely over a diamond without breaking. It holds onto your stone with a death grip that won't snap or wear down over time, making it the ultimate insurance policy for your stone.
