Details
Step-cut diamond sides give this green sapphire three-stone a calm, Art Deco line. Two emerald-cut lab-grown diamonds sit beside the round center. Their long, flat facets flash in broad planes, a quiet contrast to the sparkle of the sapphire. Claw prongs hold the center about 5.5 mm high at the 7 mm size (about 1.85 ct) on a band about 2.1 mm wide.
Choose a round center from 6 mm to 8 mm, about 1.20 to 2.75 carats. Each center is a calibrated lab-grown green sapphire, eye-clean, in a cool sea-green tone. Lab-grown sapphire is real corundum, the same mineral as mined sapphire, and rates 9 on the Mohs scale, so it wears beautifully every day. Carat weights are the typical weight for each calibrated size, so an individual stone can vary slightly.
Available in 14K white, yellow or rose gold, or platinum. The accent diamonds are lab-grown, near-colorless stones matched to the setting. Your ring is made to order in your size (US 3 to 10; see the sizing guide). Because every ring is set and sized for you, rings are final sale. More green sapphire designs are in our Green Sapphire Engagement Rings collection.

Answers, before you ask
Your Questions
Why emerald-cut sides with a round green sapphire?
The step-cut sides are crisp and white, so they frame the colored center without competing with it, and they widen the top of the ring.
How is green sapphire different from emerald?
Green sapphire is corundum, the same mineral as blue sapphire and ruby, and rates 9 on the Mohs scale. Emerald is beryl, softer at 7.5 to 8 and usually included. Green sapphire has a cooler, sea-green tone and handles daily wear far better, which is why many people choose it for an engagement ring.
Is a lab-grown green sapphire a real sapphire?
Yes. It is corundum grown in a laboratory, with the same chemistry, hardness and optical properties as a mined sapphire. It is not glass or a simulant, and every product title says lab-grown.
Will the color look like the photo?
The photos show the stone's typical sea-green tone. Green sapphire can look slightly bluer in daylight and a little warmer under indoor light, and the color reads more intense in larger sizes.
Can I have a natural green sapphire instead?
Natural green sapphires in center sizes are rare and priced individually. Email concierge@diamondandsapphire.com and we will source and quote one for you.
Can I return it?
Rings are set and sized to order, so all rings are final sale. Check the sizing guide or ask our concierge before ordering if you are unsure of the size.
