Michael B.

Great overall jeweler. Beautiful selection of jewelry with ease of online services. Site was easy to navigate through. I ordered a custom ring on March 12 and received it insured and delivered by FedEx on March 26. I am extremely satisfied and will definitely be a loyal customer in the future. Oh and yes the ring I received is perfect!!! Thank you Monclaire

Easy, quick, and quality work. I'm proposing to my girlfriend this summer and I'm glad I did it through this company.

I'M OBSESSED WITH MY RING! It's beautiful and sparkling and the stone is solid and i loved all the upgrades i did! I will definitely be purchasing more from Monclaire!!

Maggie C.

I was super nervous about ordering from an online jeweler but Monclaire was amazing! I couldn’t have asked for an easier experience. Me and my fiance designed the ring together and it is absolutely beautiful. The designing, shipping and unboxing was so easy and fun. I would definitely recommend buying from them especially because they’re so much cheaper than other online jewelers. I didn’t have to work with customer service at all because I didn’t need it resized or anything so I can’t speak to that but everything else 10/10

Monclaire had exactly what I was looking for with their website and easy way to design my dream ring! The process was stress free and we received the ring fairly quick. I highly recommend Monclaire!
