3.00 Carat Emerald Cut Diamond

Emerald cut diamonds in the 3 carat range are a stunning choice for engagement rings. Often, customers who want to maximize their beauty will choose a higher clarity grade to match their carat size. Three carat diamonds also work exceptionally well in custom jewelry, such as stud earrings and solitaire pendants. All Ritani diamonds are certified by either the AGS or GIA – the two most respected independent grading labs in the world.

Ritani has over 100 certified emerald cut diamonds around 3.00 carats in our inventory.

Carat Weight

A diamond's carat weight is a reflection of its size. 1 carat is equivalent to 200 milligrams. To best reflect its size, however, a diamond should also have a quality cut grade. Popular carat sizes near 3 carats include: 2.88, 2.93, and 2.97. For the best value, we suggest opting for a carat weight slightly lower than you planned for. What you save in this carat weight, you can use to upgrade in cut – dramatically improving the diamond's quality.

Color Grade

3 carat diamonds are available in a range of colors, from D (Colorless) to Z (Light Yellow). At Ritani, we only carry diamonds with grades from D to L, so that you can easily find a diamond of great quality. Colorless diamonds are stunning in platinum and 18k white gold, to best highlight this lack of color. They are also the most rare of the grades, and as such, more expensive. If you are planning to set your diamond in yellow gold, we suggest a Near Colorless diamond, such as an H or I. If you are concerned about any color, a yellow gold setting will make this undetectable to the naked eye.

Diamond Color Grade


A cut grade indicates how much sparkle a diamond will produce, due to its proportions and symmetry. While emerald cut diamonds are also known for their clarity, some will therefore sparkle greater than others. Cut grades range from Reserve Ideal to Poor, but at Ritani, we only carry diamonds with cut grades from Ideal to Good. You can rest assured that your emerald cut Ritani diamond is well proportioned, to sparkle. If you are considering a 3 carat emerald cut diamond, seek those with quality cut grades, such as Ideal and Very Good. This will ensure that your diamond catches the light beautifully, to balance with the carat weight.

Diamond Cut


A diamond's clarity grade – determined by a gemologist – is based on the presence of any internal inclusions. Diamonds with the highest clarity grades – FL (Flawless) or IF (Internally Flawless) – are remarkable to see. Since large open tables and step-facets characterize emerald cut diamonds, a good clarity grade is advisable. SI1 and SI2 (Slightly Included) grades indicate that there are some inclusions within the diamond. However, these are typically invisible without magnification. This makes these grades a wise choice if you are trying to balance your budget for a larger carat size, or greater color grade.

In Their Own Words

I do not think it's possible for me to be happier with my Ritani Masterwork engagement ring. When my fiancé popped the question, I literally gasped when he opened the Ritani box. The ring is breathtaking. It is absolutely stunning and not a day goes by without me receiving multiple compliments on it. Every time I look down at my left hand (which is very often, I must admit) I can't help but smile and fall in love over and over again with my ring and my fiancé. The ring is very well-made, durable, and strong; as well as beautifully crafted, made from the highest quality stones, and so sparkly! I am proud to wear this ring every day and am so pleased with Ritani's attention to detail and quality in my masterpiece. Ritani has made my every wish come true and I feel like the luckiest bride for finding the man of my dreams and getting the ring of my dreams! Thank you Ritani.

My Ritani Masterwork engagement ring is everything I could have dreamed for and MORE! I get compliments all the time, whether I am grocery shopping, getting a manicure, or simply standing in the elevator. It is definitely a show stopper! And to top it off my finance can only say amazing things about the Ritani crew that helped create my dream ring. I could not be happier with my ring and I know it will be past down for generations to come!

I do not have enough wonderful things to say about Ritani. We got engaged in January and since then I have received a compliment on my ring each and every day. Even though my ring is shared prong, it is smooth to the touch and comfortable to wear on a daily basis. Ritani's craftsmanship is exquisite and their attention to detail is second to none. I cannot wait for the day that I get to wear my matching Ritani wedding band! Thanks for making my dreams come true!

I love my ring! I've gotten so many compliments from friends, family, and even employees at stores saying it's the most beautiful and unique ring they've ever seen. My fiancé was also very happy with the price he paid for it as well and he got the matching wedding band which is also gorgeous!

- Katie, Rocky River, OH

When Aaron pulled that tiny piece of shiny heaven out of that seashell I was the happiest girl on Earth...not only was I going to spend the rest of my life with my most favorite boy, but I had the ring all little girls dream of having when they grow up and get married! My Ritani ring is beautiful and timeless and I feel gorgeous and loved every time I look down at it on my finger! It's unique and different and I will cherish it for all of my life.

- Kristin, Roanoke, VA

My Ritani ring is stunning! From the Bella Vita collection, the setting is a beautiful round halo with a round cut center stone that looks amazing with it's matching Bella Vita wedding band. I love it when the light hits it just right; I can't stop staring at the sparkles!
