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.
