How to Choose a Lab Grown Diamond Engagement Ring
Start with your budget and the details that matter most to you. Lab grown diamonds are generally a more affordable alternative to natural diamonds, giving you more flexibility to choose a larger stone or invest in a setting you love.
When comparing diamonds, look beyond carat weight. Cut quality plays a major role in how a diamond reflects light, creating the brilliance and fire you notice when it moves. A beautifully cut diamond can look more impressive than a larger stone with less sparkle. Consider the 4Cs—cut, color, clarity, and carat weight—along with the diamond's actual measurements. Both lab grown and natural diamonds can have inclusions, so check the individual stone's grading details rather than assuming one origin always means better quality.
At Leonids, individual diamonds of 0.5 carat or larger include an independent IGI grading report to help you understand their characteristics and shop with confidence.
Find a Ring That Fits Your Style and Everyday Life
The right engagement ring should look beautiful and feel comfortable long after the proposal.
Start with the shape and setting you naturally gravitate toward. A round solitaire offers timeless simplicity, while an oval or pear diamond gives a more elongated look. Halo settings add extra sparkle, and three-stone designs bring meaningful detail. For a closer look at individual proportions and styles, explore our oval engagement rings and other diamond shape collections.
Your metal type matters, too. Yellow gold adds warmth, white gold offers a clean, modern finish, rose gold brings a softer tone, and platinum is a durable choice for everyday jewelry. Before choosing, think about your daily routine. A lower-profile setting may catch less on clothing, while bezel settings offer additional protection around the diamond. Check the band width, setting height, and ring size, especially if you plan to wear your engagement ring alongside a wedding band.
At Leonids, you can explore different metals, settings, and custom details to create a ring that matches your vision.

Lab Grown Diamond Engagement Rings: FAQs
Yes. Lab grown diamonds are real diamonds created in a controlled environment rather than formed naturally within the earth. They have essentially the same chemical composition, hardness, and optical properties as mined diamonds.
To the naked eye, a lab grown diamond generally looks the same as a natural diamond of comparable quality. The main difference is its origin, not whether it's a real diamond.
Lab grown diamonds generally cost less than comparable natural diamonds because of differences in how they are produced and supplied.
This means you may be able to choose a larger diamond or a more detailed setting without increasing your budget. Actual prices depend on the diamond's cut, color, clarity, carat weight, and the ring's design.
There isn't one perfect carat size. A 1 carat diamond can feel understated and elegant, a 2 carat stone offers more presence, and a 3 carat diamond creates a bolder look.
Remember that carat measures weight, not exact visible size. A diamond's shape, proportions, and setting affect how large it appears on your hand. Choose the size you love wearing, rather than focusing on carat weight alone.
Review the diamond's cut, color, clarity, carat weight, and measurements. An independent grading report helps you understand these characteristics.
At Leonids, each individual diamond of 0.5 carat or larger comes with an IGI report. Since our pieces are made to order, final report details are provided after shipping. You can review sample reports and diamond specifications before purchasing.
