This ring features a sweeping take of 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. Petal prongs encapsulate the two pear diamonds that frame the center.
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.
All diamonds are hand-selected by our founder to meet strict beauty and quality standards — the details below are for those who’d like a deeper look.
We custom cut 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, excellent polish and excellent symmetry.
Our specialty diamond cuts minimize or eliminate the bow-tie effect for optimal performance. Read more about our Bespoke Diamonds here.
Diamond Parameters:
Color: D or E (completely colorless)
Clarity: VVS1-VS1 (eye-clean)
All of our diamonds are guaranteed completely colorless D or E color, and completely eye-clean VVS or VS1 clarity (meaning you cannot see any inclusions with the naked eye) with an emphasis on cut quality as the highest priority as it is the biggest determinant of beauty at this high of a color/clarity level.
Ratio Parameters:
Oval: 1.40-1.50
Marquise: 1.85-2.0
Pear: 1.50-1.60
We keep very strict parameters for what we will accept in regards to diamond ratio. Our diamond expert and founder Michelle Keller hand selects the diamond for each ring depending on the setting style, number and position of the prongs, as well as presence or absence of accent stones.

We craft our rings by hand. The ring you see online is a close representation of what your custom piece will look like, but your ring is made by artisans and not by computer or machine. Our experienced jewelers hand finish every single piece, so any subtle differences are what make your ring unique.
Because each piece is custom crafted specifically for you in the stone size/type, metal type, and ring size you choose, it is not eligible for return.
We want you to feel completely confident in your decision. If you have any questions prior to purchasing, please contact us at hello@thebijoulab.com. We’re always happy to provide additional images, videos, or detailed product information to support your selection.
Every piece of Bijou Lab jewelry is created to make a lasting impression. For this reason, all Bijou Lab jewelry pieces are covered by our Limited Lifetime Warranty.
We guarantee that every Bijou Lab piece is crafted to the highest standards of fine jewelry workmanship. Should your piece arrive with a manufacturing defect, we will repair or remake it at no cost to you.

Using our Ring Size Chart
Our Ring Size Chart includes US sizing, UK/Australian sizing, and inside diameter and circumference measurements for reference. This is helpful if you already know your size, are converting from an international size, or are measuring a ring you currently own.
For the most accurate fit
If you’re unsure of your size or between sizes, we recommend using a professional ring sizer—HERE is the gold standard sizing tool used by our master jewelers and setters.
Fit tips
- Fingers naturally fluctuate throughout the day and across seasons
- A well-fitting ring should feel snug and take a few wiggles to get off
- If you’re between sizes or have a larger knuckle, choosing the slightly larger size often feels best long-term to allow for swelling/fluctuation
Each ring includes one complimentary resize within six months of purchase, should a size adjustment be needed.
All orders are fully insured during transit. In the rare event a package is lost or damaged in shipping, we will work with the carrier and remake the piece as needed.

My fiancée gave me a few must-haves when it came to choosing her engament ring: she wanted an oval gemstone, in a tri-stone setting, that was either silver or platinum with some vintage flair. This Vintage Monaco 3 Stone absolutely fit the bill! She’s always been partial to lab-grown, and Bijou Lab knows what they’re doing when it comes to the stunning moissanite in this setting. It’s practically indistinguishable from diamond, and way more shiny, in my opinion. The view from the side is what sold me on this ring - it’s flower-like and absolutely gorgeous with the added stones on the band. I was kept updated at every part of the creation process, and loved the video they sent of the final product before it was shipped out. I can tell they really care about each piece they create, from the luxurious packaging to the hand-written note of gratitude. We couldn’t be happier with this beautiful start to the next chapter of our love story!
I found this company on social media and had sent my bf countless videos for inspiration as i was simply obsessed with all of their designs and fell in love with their gorgeous and unique bespoke movals. I also loved how committed they are to reducing environmental impact by sustainable sourcing. Little did I know I would be lucky enough to have one of my own most special custom rings very soon!! It is safe to say my fiancé and I are absolutely in love with our semi-custom Vintage Monaco Moval Trilogy!!! It is absolutely stunning, so dreamy, and overall perfectly radiating. The cathedral setting with the intricate pave bridge diamond details, to the gorgeous floral tulip basket makes this ring truly one of a kind and emanates a vintage beauty. Our ring was perfectly curated by the Bijou Lab team, we will love it for a lifetime, and always be grateful that they are a part of our love story.
The service was excellent, and the company was awesome. They did a fantastic job on the ring. I was extremely happy with the entire process and the timely updates.
My fiancée and I could not be happier with how the vintage Monaco three stone turned out. The customer service team was stellar in answering all my questions and helping me choose just the right ring for my fiancée!The ring itself is gorgeous, the diamond radiates like no other and the fine detail on the sides adds a perfect little touch! With six prongs, the center stone is also very secure which was important to us. Thank you so much to the Bijou Lab team for helping to make our engagement special. Would highly recommend!
Beautiful ring, perfect fit, my partner loved it!! Amazing customer service too, they emailed at each step of the process and provided a thorough updates!
