Color refers to the natural tint of a diamond. The closer the diamond is to “colorless” the rarer it is. The industry standard to grading color in a diamond is to assign a letter grade from D (colorless) to J (nearly colorless)

Most diamonds have imperfections in the form of internal flaws and surface blemishes. These imperfections are graded on a scale of FL (flawless) to I1-I3 (included). FL diamonds are the rarest and hardest to find.

Carats measure a stone’s weight. The higher the carat weight, the heavier and bigger a center stone. Use the slider to see how diamond size changes with carat weight.

The size of a diamond is proportional to its carat weight. When rough diamonds are cut and polished into finished diamonds, up to 2/3 of the total carat weight may be lost. Since larger rough gems of high quality are found less frequently than smaller rough gems of high quality.

CUT
Clarity
Good
Very Good
Excellent

A diamond’s cut measures its anatomy and ability to reflect light. Cut grades go from “Excellent” to “Poor”. Well-cut diamonds have outstanding proportions with immense fire, brilliance, and scintillation.

Great overall jeweler!

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, Quality

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

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!!

Ivonne Dobarganes - US, Apr 4, 2025

Highly recommend!

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

Maggie Cape - US, Apr 4, 2025

The ring of my dreams easily designed!

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!

Love story
We got engaged while on vacation in Exuma. Kyle proposed on the most beautiful beach in the Bahamas, with nobody else in sight, and the most stunning ring at sunset. It was perfect!
Monclaire experience review

"After exploring custom rings with several online retailers, Monclaire was by far the most responsive, accommodating, and helpful from the very first DM exchange! Their service has been outstanding, and the ring is more breathtaking than we could have ever imagined! We cannot wait to visit the store to pick wedding bands!"

Love story

My fiancée and I flew out east to PEI to visit his family and explore the island. When we decided to make this trip in December 2021, he knew that’s where he wanted to propose to me. He secretly collaborated with our 2 best friends on which ring to get, and how to get it out to the island without me knowing. We went down to the beach to “take photos before dinner”, and as I was fussing over what I was wearing, he looked at me and said, “I think you’re missing something important for this picture”, got down on one knee, and asked me to spend the rest of our lives together when he opened the box and I saw the ring, I just about died, it was exactly what I pictured having as an engagement

Monclaire experience review

"I found my dream ring on Monclaire almost a year before I got engaged, and my fiancée came through! The ring shipped quickly to Canada, and the quality so far has been amazing. I’m a nurse and occasionally wear my ring to work. The shine and band both have been holding up beautifully!"

Love story

Our day was so special filled with family and so much love! My fiancé Josh told me we were going down to our favorite beach in Laguna for a friend's birthday — a normal occurrence so didn’t think anything different for a second! We get to the top of the stairs to walk down, and he then asked to take a picture of me at the top before the special moment. We walked down and he said we were around the corner on the private side since it was a smaller intimate birthday. We then walk towards the private side and I see that it was pretty empty, but again, didn’t think anything of it. We walk up closer to the picnic that was set up, and in my mind, I thought, “That blanket and spot are pretty small for guys who are 6’5!”

As we got closer, I then saw the Monclaire box and how beautiful the setup was and knew right there, “Holy moly I know exactly what is happening now!” I couldn’t stop smiling and giggling because of how perfect this moment was and it was by far the easiest yes ever. My two best friends then popped up from behind an umbrella further away — they were there taking pictures and videos of our special moment, which was so much more special than I could have ever imagined. We had some time together to take pictures, celebrate with champagne and princess what just happened! We then went back up to the car, and drove back home, only to find all of our closest friends and family waiting to celebrate and love on us even more!

The whole day was filled with so much love, celebration, and excitement, and the ring was so worth the wait. I still stare at it constantly and will never get over how great it turned out. Thank you so much to the Monclaire family for making our special day so much better!
