Save 20%The Emerald and Round Lab Grown Diamond Shared Prong Eternity Wedding Band from Mapple Gems is a wide, glittering band that pairs a run of emerald cut lab grown diamonds with a group of round brilliant lab grown diamonds. The mix of long step cut stones and round stones gives the ring a rich, layered look, and the shared prongs keep the setting light so the diamonds take center stage. It is a statement band for someone who wants real presence on the finger.
Style: eternity style wedding band with a close row of diamonds set in shared prongs. In the product photos the row of stones continues around the band.
Stones: emerald cut lab grown diamonds together with a group of round brilliant lab grown diamonds. The total weight is 4.50 carats TW, based on the product name and the size of the stones shown in the photos. The exact stone count and total carat weight can vary slightly with ring size so that the proportions and fit stay balanced.
Stone quality: EF color and VS1 clarity, as given for this design.
Setting: shared prong setting. The photos show the ring in white metal, and it can be made in any of the metals listed below.
Finish: polished metal.
This design is a band of diamonds without a single larger center stone, so the 2 to 5 carat center stone sizes used on our engagement rings do not apply to 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 makeup, crystal structure and physical properties as a mined diamond, but it is grown in a lab instead of being dug from the earth. It rates 10 on the Mohs scale, the highest hardness there is, so it stands up to everyday wear, and it is a conflict free choice for couples who want a brilliant stone with a clear origin.
This band suits brides who want a wide, high impact band with a mix of diamond shapes. It is a statement wedding band, an anniversary band for a big milestone, and a gift for her that is meant to be noticed.
The photos show emerald cut diamonds together with round brilliant diamonds in the same row. This mixed layout adds variety to the sparkle while keeping the overall look balanced.
The row of stones in the photos continues around the band. If you would like a particular layout, such as stones across the top only, please contact Mapple Gems before you order and we will advise you.
Yes, although this is a fuller band, so it pairs best with a simple engagement ring. Tell us your ring style and we can advise how the two will sit together.
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.
