3 Stone Engagement Rings with Lab Grown Diamonds

Yes. Leonids offers Esme with an oval lab grown center diamond and pear side diamonds, Jade with an oval center and oval sides, and Ophelia with an oval center and half-moon sides. Compare the side-stone shapes, measurements, and complete ring prices to choose your design.

An emerald-cut center option is not currently listed in this three stone collection. Contact Leonids to confirm whether we can source the center diamond and make your chosen setting. Specify whether you want an emerald center with other side-stone shapes or three emerald-cut diamonds. Confirm the design, quote, and custom-order terms before ordering.

You can shop lab grown 3 stone diamond rings at Leonids and compare the listed designs, metals, and center-stone sizes. Check the complete ring price, center-diamond report information, and side-stone specifications. Review the delivery estimate and return terms for your selected order before buying.

Review the center diamond’s grading report and the side stones’ listed specifications. Compare the pair’s measurements, color, and appearance beside the center diamond. View the ring from above and from the side to check the setting and overall proportions. Also confirm which diamonds have grading reports and whether the quote includes the complete ring.

A 3 stone engagement ring usually gives you more finger coverage than a solitaire. The two side diamonds spread the design across the hand and create a wider look. Compare the total carat weight and stone measurements instead of looking only at the center carat.

Pear side stones soften the look of an oval or radiant center diamond. Pair half moon diamonds with an oval center for a smooth outline. Tapered baguettes give an elongated cushion center diamond a clean, modern look. Round side stones add balance. Matching marquise side stones give a marquise center a long, flowing shape.

Smaller side stones keep the center lab grown diamond as the main focus. Larger side stones add more finger coverage and create a bolder three stone ring. Compare the width of each diamond in millimeters because different shapes can look larger or smaller at the same carat weight.Source: Elle Cassie’s 3-Stone Engagement Ring.

First, check your ring size and the full width of all three stones. Look at the center diamond's length and width, not just its carat weight. Oval, marquise, elongated radiant, and elongated cushion diamonds give you more length across the finger. Choose a size that looks balanced and leaves room beside your other fingers.

A prong setting shows more of the diamonds and creates a classic look. A bezel setting adds a smooth metal edge around the center stone for a clean, modern profile. A cathedral setting lifts the center diamond higher and may leave more room for a wedding band, but you should still check the side view and setting height.Source: Jewelers Mutual Ring Structure Guide.

Not every straight wedding band will sit flush with a three stone engagement ring. A low center setting or wide side stones may leave a small gap between the rings. A curved, open, gap, or custom lab grown diamond wedding band can follow the engagement ring more closely.Source: Brides Engagement Ring Setting Guide. ELLE Custom Engagement Ring Guide.

Yes. Lab grown diamonds are real diamonds created in a controlled laboratory instead of mined from the earth. They have the same crystal structure, hardness, and sparkle as mined diamonds, but their origin is different.

Leonids provides an IGI report for the certified center lab grown diamond. The report records details such as carat weight, color, clarity, measurements, and the report number. Smaller side diamonds may appear in the product specifications without separate grading reports.Source:IGI Lab-grown Diamond Report Explanation. IGI 2025 4Cs Statement.
