Diamond Academy - Learn all about diamonds before you buy
Looking for the perfect 1 carat diamond ring? Learn everything about size, value, and why 1 carat diamonds are perfect choice for engagement rings and diamond earrings.
If you're shopping for a diamond ring or earrings, chances are you’ve come across the 1 carat diamond. It’s a classic choice—elegant, eye-catching, and just the right size for many styles and budgets. But what exactly does 1 carat mean, and why are lab-grown 1 carat diamonds so popular in Singapore and globally?
What Does “1 Carat” Really Mean?
A carat is a unit of weight used to measure diamonds and other gemstones. One carat is equal to 200 milligrams. But here’s the key: carat weight isn’t the same as size. The way a diamond is cut can affect how large or small it appears.
For example, a 1 carat round brilliant cut diamond typically measures about 6.4–6.5mm in diameter. Other shapes, like ovals or pears, can look bigger even at the same carat weight.
Here’s a rough size guide for different cuts:
- Round: ~6.4 mm
- Oval: ~8 x 5.5 mm
- Emerald: ~6.5 x 5 mm
- Cushion: ~5.5 x 5.5 mm
- Princess: ~5.5 x 5.5 mm
- Pear: ~8.5 x 5.5 mm
So if you're asking, "How big is a 1 carat diamond?", it depends on the cut. But generally across all shapes, it's considered a perfect balance between presence and practicality.
Whether you’re buying for an engagement, anniversary, or personal milestone, a 1 carat diamond ring is a meaningful choice.
What is better: a 1 carat or 2 carat diamond?
For those seeking a traditional option, a 1 carat diamond is ideal. However, if you desire a larger and bolder appearance, a 2 carat lab grown diamond, appearing up to 50% larger, may be a perfect choice.

Let customers speak for us
love the purchase, unbeatable pricing for this quality. Was worried it might be too large at first but fell in love when I saw it in person!
Bought this for Mother's Day and my mum was simply delighted. She said it was super bright and luminous! Appreciate the nice packaging box and bag and fast same day delivery!
My fiance loves it so much! Thank you for making us such a beautiful 3 carat diamond ring!
Love the sparkle on this pair! I had other solitaire studs which were harder to wear daily especially when sleeping. These studs have a nicely designed secure backing but they are so comfy.
Having toiled all these years, I rewarded myself with a big solitaire on my xxth birthday but ouch, how expensive at $xx,xxx!
Bye bye expensive diamonds... no more 5 figure spending!
I am soooo pleased with my solitaire ear studs from Carat Heritage ... Diamonds are women's best friend and so are you, Ashley! You are superbly patient, know your customers and have a good eye!
Clean, chic, and guilt-free. These diamond studs are now part of my daily uniform.
Love the ring we received. It’s really bright and catches the light perfectly. Have received many compliments about the sparkle since I started wearing it.
The Art of Handpicked Perfection
More Than a Certificate
At Carat Heritage, we believe that true brilliance isn’t just about meeting standards—it’s about exceeding them. While certificates like IGI or GIA provide valuable technical insights into a diamond’s quality, they can never fully capture the beauty, fire, and soul of each stone.
That’s why every diamond we use is more than just certified; it’s handpicked by our experts, who examine each stone with their own eyes.
