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 Toi et Moi Necklaces

Welcome to the absolute peak of fine jewelry. Our platinum lab grown diamond Toi et Moi necklaces are the ultimate choice for true jewelry purists who want zero distractions. Platinum is naturally pure white, thirty times rarer than gold, and completely hypoallergenic. Because it never changes color or requires replating, it holds high-impact, contrasting diamond shapes in an ice-bright grip that maximizes true colorlessness and clarity.

Why Choose a Platinum Lab Diamond Toi et Moi Necklace?

Choosing platinum is an investment in absolute, uncompromised longevity. Unlike white gold, platinum is a dense, pure white metal that will never tarnish or reveal warm undertones over time; instead, it develops a beautiful, historic satin patina that can easily be polished back to a mirror finish. Because of its incredible density and resistance to metal loss, platinum holds your hand-selected, certified lab grown diamonds with unrivaled security. Suspended from our heavy, premium platinum chains, it offers a grounding, luxurious physical presence on your neckline that is engineered to last a lifetime.

How to Style Your Two-Stone Diamond Pendant in Platinum

Platinum is sleek, clean, and highly structural, making it the perfect match for minimalist tailoring, sharp-shouldered blazers, and structural evening gowns. Let a high-impact Platinum 3ctw Toi et Moi Oval and Pear Lab Grown Diamond Necklace or our architectural Platinum 2ctw Toi et Moi Emerald and Pear Lab Grown Diamond Necklace serve as your singular, high-end statement piece over an all-black ensemble. For an editorial look that amplifies this cool-toned, unrivaled brilliance, style our signature Platinum Duo Drop Round and Pear Lab Grown Diamond Necklace alongside our certified platinum lab diamond prong-set studs.

FAQs

What are the main benefits of choosing platinum for a Toi et Moi necklace?

Platinum is the ultimate luxury metal standard. It is naturally pure white (so it will never change color or require rhodium plating), and completely hypoallergenic. Because of its extreme density and strength, it holds your certified lab diamonds in an ice-bright, unyielding grip that maximizes stone clarity and true colorlessness.

Does platinum scratch, and what is a platinum patina?

While platinum is incredibly strong and resistant to breaking, it is a ductile metal, meaning it can develop minor surface scuffs over time. Instead of losing metal when scratched (like gold does), the platinum merely shifts out of place, creating a beautiful, soft, historic satin look known as a "patina." If you prefer a mirror-bright shine, a jeweler can easily buff it back to a high polish at any time.

Why does a platinum necklace feel different on the neck than gold?

Platinum is significantly denser than gold, making it roughly 60% heavier than 14K gold. When you wear a piece like our 5 ctw Duo Drop Round and Halo Pear Lab Grown Diamond Necklace in Platinum, you will instantly notice a substantial, grounding, and high-end physical weight on your neckline that feels incredibly luxurious.

Is platinum completely safe for people with severe metal allergies?

Yes. Our platinum Toi et Moi necklaces are crafted using a 95% pure platinum alloy (PT950), making them completely hypoallergenic. It contains zero nickel or base metal allergens, making it the perfect, safest option for anyone with highly sensitive skin or diagnosed contact dermatitis.

How do I clean and maintain a platinum twin-stone diamond pendant?

Platinum is incredibly low-maintenance. Because it doesn't tarnish or react to environmental chemicals, you can keep your necklace clean using standard warm water, mild dish soap, and a soft baby toothbrush to remove daily lotions and oils from underneath the diamond settings.
