This ring features our brand's signature Vintage Pave Bridge; an ode to both the old and the new, a dual-sided sparkling arch of hidden diamonds with an enchanting milgrain border to add a touch of vintage beauty underneath.
The oval rests within our beloved Latticework Petal Prongs; a romantic bloom of petals that weaves around the center stone.
Our design's proprietary overlapping tulip petals are not only beautiful; they give the prongs added security due to the interlocking nature of every prong. A regal tapered cathedral is the finishing touch that adds both support and elegance.
The Vintage Pave Bridge feature was designed with extraordinary intention so the stones are set slightly recessed and the milgrain is set above the level of the stones to form a small barrier so your wedding band doesn't get scratched by the stones and your wedding band doesn't subsequently wear down the prongs holding the pave (leading them to fall out). This means the pave bridge can safely be featured on both sides of this ring.
We custom cut and hand select the top quality lab diamond center stones for every ring which are guaranteed premium D or E color and completely eye-clean VVS/VS1 clarity.
Our specialty diamond cuts minimize or eliminate the bow-tie effect for optimal performance. Read more about our Bespoke Diamonds here.
We custom cut or custom source stones with ideal cut proportions and ratio for optimum light return and minimal to no bow tie in our elongated cuts.
Stones are guaranteed excellent symmetry and polish.
We are picky with who we work with and only source and produce from a small number of high-quality, eco-conscious growers and screen for blue, gray, and brown color tinges, strain and striation to ensure you receive only the most premium lab diamonds available on the market.
Pavè stones in rings with a moissanite center stone are moissanite by default unless stated otherwise.
Pavè stones in rings with lab diamond center stones are automatically upgraded to lab diamonds.
Pavè stone quality is DEF VS+.

The process of ordering the ring was smooth and easy, everyone who assisted me in the process was so helpful and professional. It came on time and it was so perfect I was struggling to keep the secret from my significant other.
From my now fiancé: thank you so much for creating my dream engagement ring! It is so beautiful and could not be more perfect! So beautiful I still can not get over it!
Ever since I saw the Vintage Monaco, I knew it was my dream ring. I’ve had it saved for months and every time I saw it online I’d get so excited. I love flowers more than anything and the design was sooo unique to me. And let me tell you, when I saw it in person, it felt unreal…and it feels even more unreal when I see it social media and I can just look down at my finger and see it in real life hehe. My favorite compliment is that people say the ring is so me and that makes me giggle because I just know how stunning this ring is!! I honestly couldn’t be happier with this beauty that I’ll treasure forever - thank you Bijou Lab ❤️🔥
Vintage Monaco, Oval Cut
My husband got my dream ring Bijou Lab and I am so so beyond blessed to have them as the team to make my ring. Even though I had to resize and I wasn't sure what size, they were so so kind in emailing me back and forth and helping me figure out what would be a good size for my new ring size and all. It's literally shining and I love having it back on my finger!
Super smooth and transparent process - we didn't feel pressured at all and the team at Bijou Lab answered all our questions before ordering. Ring was safely delivered after 6-8 weeks (right on time!) and we were updated throughout the whole process. Wife was absolutely thrilled and in love with the details, quality and craftmanship! Thank you again - highly recommended!
