Our most popular setting began as a sketch on a napkin in a small cafè along the canal in the neighborhood of Jordaan in Amsterdam; surrounded by the vibrant, iconic blooms of tulips that Amsterdam is so well known for.
Our Amsterdam 3 Stone Classic design romances with its swaying floral prongs encompassing the pear lab diamond side stones and perched atop a beautiful, sweeping one-sided pave bridge for ultimate stackability.
Our romantic Signature Lotus Flower petals twist up like vines into double claw prongs that encompass the sparkling center stone.
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.
