Learn About Your Diamond

You’ve selected a 3.05 carat round lab diamond. 0% of our users choose round diamonds. Learn more about them here.

Cut is the most important factor. When an experienced gemologist picks up a diamond grading report, their eyes go to very specific values. They are looking to see if these fall within the desired ranges. Seemingly unimportant values like the depth percentage have a large effect on how your diamond will sparkle - and these values differ for each shape.

Follow the checklist prepared by our gemologists to see how your diamond fares. If it misses by a little bit on one or two, that’s fine, but we recommend trying to find a stone that passes on all:

Your 3.05 carat round lab diamond is graded E color (Colorless), and you can read more about E color diamonds here.

Color is graded beginning with D (Colorless). Learn more about diamond color here. The market prices colorless diamonds higher as they are rarer, but some people prefer warmer colored stones.

Your 3.05 carat round lab diamond is graded SI1 clarity, which stands for Slightly Included 1. Read more about SI1 clarity diamonds here, or learn more about diamond clarity in general here.

There are minimum clarities our gemologists prefer for each shape, but beyond that clarity is a matter of budget and preference. People typically aim for an eye clean stone. Also, our gemologists have certain deal-breakers when it comes to clarity. For example, our gemologists always avoid stones with a cavity, because with one wrong hit your diamond can crack.

Use the checklist below to ensure your diamond passes. Consult us before purchasing to see if any other nuanced issues are present:

A diamond's carat weight is determined by its size, with larger diamonds weighing more. Learn more about carat here.
However, it's important to note that carat weight is not the same as size, as other factors such as depth and shape can also impact how large a diamond appears.

I wanted to customize an engagement ring to include my children's birthstones doubling as a mother's ring. From the very beginning they were fantastic! Including the owner! I had the best experience! When I received my completed ring, I was extremely happy! Quality is stunning! I was initially hesitant to order something that expensive and important off the internet, but was proven to be a wonderful experience! I can't say enough good things about it.

We were looking for an eternity band with lab-grown diamonds and had gone to local brick and mortar to get some ideas, but the prices were ridiculous. I found Rare Carat in a search and loved everything the site had to offer, and found a band i really feel in love with. But to buy an expensive purchase like an eternity band? We were hesitant. We checked every review we could find and couldn't find anything negative about them! Everything was 5-stars and their return policy seemed on the up-and-up. I even asked questions through their GIA hemolytic chat and got all my questions clearly answered.<br><br>Using a credit card "just in case" and bit the bullet. We got instant confirmation by email and a few days later, I got an email to confirm my address. There was a delivery target date range of a few days (Aug 13-17) and on Aug 12, I got a FedEx tracking number and on the 13th, my ring was in my hands!<br><br>The ring is beautiful and the bonus earrings were a nice touch. We are really happy with the quality and it compliments my wedding set perfectly! We will definitely consider Rate Carat for future purchases.

RE: Rarecarat.com. I was skeptical about purchasing my platinum wedding band online, but the reviews I read were outstanding. So, I took the plunge. So many beautiful options! I fell in love with the Linda Curved Pavé Diamond Band. Once I placed the order I received the ring on time as promised. I had to sign for a regular brown box, as promised the company was discreet with their shipping. I love the white box my ring and gift came in. I asked my husband of 42 years to open up the package and put the ring on my finger. He did…so special. I love my ring! Its quality is outstanding. The diamonds are beautiful and perfect! I’m so in love. Thank you for making my dream come true. The price was perfect and made it all possible. Sincerely, Syl from NY

Pretty crazy mix of quality, speed, price and customer service. They resized my wife’s tennis’s bracelet and refunded me for the diamonds they took out. Their employees also all appear to be domestic. I’m really impressed at this company

I truly cannot recommend Rare Carat enough. We purchased our engagement ring from them two years ago, and from the very beginning, they made what could have been an overwhelming experience feel easy and reassuring.<br><br>Shopping for such an important piece of jewelry online initially felt like a risk, especially when I had very specific concerns about choosing a pear-shaped diamond. I was particularly worried about avoiding a bow tie as much as possible, and I communicated all of my concerns to the Rare Carat team. They took the time to understand exactly what I was looking for and helped us find the most beautiful ring while addressing every concern I had. I never felt pressured or pushed toward a more expensive option. Instead, they genuinely wanted to help my fiancé find the perfect ring for me and made the entire experience seamless.<br><br>Throughout the process, I communicated with Ajay, who was absolutely wonderful. He was incredibly responsive, usually getting back to me within just a couple of hours, and he always took the time to answer every question I had. No question ever felt silly or annoying, and I always felt like he genuinely cared about making sure we were comfortable and confident with our decision. Rare Carat was honest, ethical, kind, and transparent throughout the entire process. I never felt like they were trying to make the most money possible from us or convince us to overspend. They truly had our best interests in mind.<br><br>Fast forward two years, and we found ourselves needing to purchase our wedding bands at the last minute. I immediately reached back out to Ajay, and once again, he and the Rare Carat team made the experience incredibly easy. We were able to find wedding bands that were exactly what we were looking for, and they were delivered so quickly despite the time crunch.<br><br>These purchases can be incredibly stressful when you're working with the wrong people, but Ajay and his team make you feel like you have someone in your corner. They are honest, caring, responsive, and genuinely want their customers to be happy. The fact that we came back to Rare Carat two years later for our wedding bands says everything about how much we trusted our experience the first time around.<br><br>I truly had no issues whatsoever with Rare Carat, and I would wholeheartedly recommend them to anyone looking for an engagement ring, wedding bands, or any fine jewelry. I am so grateful for the care they put into both of our experiences and could not be happier with our rings!
