If you’re planning to purchase a 4 carat lab grown diamond engagement ring, you need to know that the size is far more impressive than you think, about 4 times the size of a 1.0 carat diamond. It will be a show-stopping centerpiece on your fiancée's finger, with fire and brilliance that sparkle like no other.
Since carat refers to the diamond’s weight rather than visual width, a 4 carat lab grown diamond ring will look different depending on the stone’s cut. For the most common round brilliant 4 carat diamond ring, it measures approximately 10.2 mm to 10.4 mm in diameter. On average, this covers roughly 70% of a finger, leaving only the edges of skin to peek through.
If your ring needs to make a statement, you must consider elongated shapes for your diamond’s cut, like the oval, pear, and marquise. They have a larger surface area, making your 4.0 carats appear bigger than a 4.0 round or princess cut diamond ring. Shapes like the Asscher or deep-cut cushions carry more weight on the bottom, making them look smaller but offering far more depth and stability in the stone.
When placed side by side, they are impossible to tell apart unless you have specialized equipment at hand. Mined and lab grown 4-carat diamonds are the same chemically, physically, and optically. They both rank a 10 on the Mohs scale of hardness. The only difference is their origin story: one naturally mined from the earth and the other grown in a controlled lab setting.
A high-quality 4-carat mined diamond is a true rarity in nature and can easily cost between $60,000 and $100,000. However, a 4 carat lab grown diamond engagement ring typically ranges only between $2,000 and $5,000 (sometimes more if the design is complex). This allows you to purchase a celebrity-sized diamond ring for a fraction of the cost, making luxury jewelry truly accessible and customizable at an affordable price.
The reason mined 4-carat diamonds are so expensive is due to their rarity in nature. Lab grown diamond rings of 4 carat do not mean lower quality since they are evaluated on the same 4Cs as mined diamonds by the IGI or GIA. In fact, you usually get a cleaner 4-carat stone with better color consistency and clarity if it is lab-grown, since the growth process is far more predictable.
CaratBee’s lab grown diamond engagement rings are the more ethical choice in comparison with mined diamonds. Since they are made in high-tech facilities, there is no mining or habitat destruction required in the manufacturing process. By choosing a 4 carat lab grown diamond engagement ring, you are contributing to a sustainable future in the jewelry industry.
When you invest in buying a 4 carat lab-grown diamond ring, the cut becomes the most important determining factor. Your sparkle literally depends on the quality of the diamond cut. Always ensure to only buy an "Excellent" or "Ideal" cut so your diamond shines brilliantly on your beloved’s finger.
Aim for a clarity grade of VS1 or VS2 to ensure the stone is eye-clean, that is, no visible imperfections appear to the naked eye. For color, the G to H range is appropriate, colorless to the naked eye, and cheaper than the D-F range.
Every 4 carat diamond ring at CaratBee is independently certified by the IGI. You can be 100% confident in your purchase since your cut, carat, color, and clarity will all be mentioned in this report, authenticating your purchase.
A 4 carat round diamond is approximately 10.2 mm wide. It is a bold, noticeable stone that covers a large portion of the finger, making a definitive luxury statement.
