"I can't say enough about the experience I have had with Bijou Lab. Michelle made sure every detail was talked about. She was honest, thoughtful and truly cares about each project. I can't recommend Bijou Lab enough. It was worth every penny. The design I wanted was a unique curved band and it turned out better than I ever expected. It is absolutely perfect. Don't hesitate, you will NOT be disappointed."

I had purchased the Monaco Design from Michelle for my engagement ring. She was responsive to my inquiries and concerns. She helped me pick out my diamond and it was gorgeous. I am extremely grateful for Michelle's transparency and expertise. I cannot say thank you enough! Everyone loves the ring, especially my partner! People can't seem to stop asking me where I got it, but now they know!

"The moment I saw this setting- I knew this was THE ring. I messaged Bijou Lab and was able to work towards customizing the design to add the features I had dreamed of. Michelle was extremely knowledgeable and caring throughout the process...Working with Bijou Lab felt professional and luxurious, while maintaining the personal, welcoming energy that most brands don't find a balance for. I will be recommending Bijou Lab to anyone and everyone!"

I found Bijou Lab last year and immediately knew I wanted work with Michelle and her team to make my Moissanite engagement ring. Her social media page has so many educational videos and you can really tell she cares about the quality of her work. My fiancé emailed Michelle with some questions and Michelle was quick to respond and even sent an educational article about moissanite stones. My ring is beautiful! I’m absolutely obsessed. I’m so happy I chose Bijou Lab to make my forever ring.

"My fiancé reached out to Michelle last year and ever since, it has been such a pleasure working with her. I gave my fiancé an idea of my dream ring (he didn’t want me too involved so it would be a surprise) and Michelle literally helped him make the ring of my dreams come true!"
