For the lover of flowers, a round brilliant stone rests within our signature Latticework Petal Prongs and a regal tapered cathedral.

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 golden bridge underneath, adorned with dancing flowers and a weaving vine is reminiscent of the wild blooms in the mediterranean landscape along the French Riviera.

Expert Diamond Curation

All of our ring purchases include an expert curation service where our founder and diamond expert, Michelle, hand selects the ideal diamond to ensure that it meets the highest standards for excellence. The diamond is selected for the exact setting that it is going into, with regards to a multitude of factors including but not limited to: the diamond cuts proportions, the number of prongs, prong placement, setting style, ring size, band width, and the presence or absence of side stones. Our stones are always custom cut in very strict balanced ratios; if you have specific diamond requirements you'd like to have met, please reach out to us via email!

Amazing Customer Service and Ring!

Bijou Lab is fantastic! We purchased a Monaco, Round Brilliant Cut and thoroughly appreciated the company's attention to detail, communication, and delivery. Both the product and service were truly fantastic.

Perfect ring

We had a truly incredible experience with Bijou Lab. My partner proposed with a Ring Pop so he could surprise me and then design the ring thereafter. We looked at many, many rings and kept coming back to this design. We were able to create this as a semi-custom project by substituting a one-sided classic pave bridge with sapphires. Megan promptly answered my many questions, helping us decide everything from carat size to sending videos of multiple different color options of sapphires to helping us figure out if this ring would stack flush with a band from another jeweler (it will!) Furthermore, two days after we had placed the order I saw on the Bijou Lab instagram a story of a ring with a European shank and they were able to add that on to the ring for a $250 additional charge. I don't have a traditional ring to compare it to, but my top-heavy ring does not spin and is very comfortable so I am very glad we went with this shank style. Another consideration is that Michelle chooses the diamond (within the parameters of the carat size you choose, D/E color, and VVS/VS1 clarity). This is different than a lot of the other online jewelers where they have those huge databases of diamonds. We knew we wanted a lab diamond but were overwhelmed by the sheer amount of choices and being able to evaluate a stone based on a single online 360 video. With the ring in hand, I am so grateful we trusted Michelle and the diamond on my hand is the most brilliant one I have ever seen in person. I feel so lucky and grateful that we went with Bijou Lab - they were so kind, patient, responsive, and now I have a delicate and durable engagement ring that I am proud to wear.
