Save 20%The Round Lab Grown Diamond Four Prong Half Eternity Wedding Band from Mapple Gems shows off each diamond on its own. Round brilliant diamonds sit in a row, each held in its own four small prongs with a little space between, so every stone catches the light. It is a light, airy take on the classic half eternity band.
Style: half eternity wedding band, with the diamonds across the front of the ring and a plain polished shank at the back.
Stones: round brilliant lab grown diamonds with a total weight of about 0.38 carat. The stones graduate slightly in size, with the largest at the center.
Stone quality: EF color and VS1 clarity, as listed in our source specifications.
Setting: each diamond has its own four prong setting, with a small gap between stones.
Finish: high polish, shown in rose gold and yellow gold tones. The band width is not listed in our source data, so please contact us if you need an exact measurement.
This design has no single center stone, so the center stone sizes used on our engagement rings do not apply to this listing. Some photos show the band stacked with a cushion cut solitaire ring and a plain gold band. Those rings are not included with this listing.
Choose from 925 sterling silver, or solid gold in 10K, 14K and 18K. Gold is available in yellow, rose and white. Each ring is made to order in the metal you select, so please allow time for it to be crafted before it ships.
Available in US ring sizes 2 to 14. If you need a custom size, contact Mapple Gems and we will help you.
Lab grown diamond is real diamond. It has the same chemical and physical properties as a mined diamond, but it is grown in a laboratory instead of being dug from the earth. It rates 10 on the Mohs scale, the highest possible hardness, so it is well suited to a ring worn every day, and it is a conflict free choice for couples who want a brilliant diamond with a smaller footprint.
This band suits anyone who wants a diamond band with more air and individual sparkle than a pave row. It works as a wedding band, an anniversary ring, a stacking ring, or a gift for her, and it pairs well with a solitaire and a plain band in a stack.
A half eternity band has diamonds across the top part of the ring only, while the back of the shank is plain metal. This makes it comfortable to wear and easier to resize than a full eternity band.
Yes. The slim profile stacks well with a solitaire engagement ring and a plain band, as shown in some of the photos.
Yes. A lab grown diamond is a real diamond with the same chemical makeup, hardness and sparkle as a mined diamond. The difference is only where it was grown.
Clean it with warm water, mild soap and a soft brush, then dry it with a soft cloth. Remove it before heavy work, swimming or using harsh chemicals.
Yes. Each ring is made to order in your chosen metal and size, which lets us fit it properly to you.
