Harper Art Deco 3 Carat Lab Grown Elongated Cushion Diamond Engagement Ring
3 Carat (3ct) Elongated Cushion Cut Lab Grown Diamond Art Deco Engagement Ring
Celebrating 1920s geometric glamour and architectural proportion, this bespoke Art Deco engagement ring showcases a 3 Carat (3ct / 3 ct / three-carat) elongated cushion cut lab grown diamond graded at Color E, Clarity VVS2, and Ideal cut. Engineered with a 57-to-58 facet matrix that maximizes fire and suppresses central bow-tie shadowing, the elongated cushion center stone is framed by 0.28 carats of round brilliant and step-cut baguette side diamonds (Color F-G, Clarity VS1-VS2) for a Total Carat Weight (TCW) of 3.28 carats.
Cast in your choice of solid 18K Yellow Gold, 18K Rose Gold, or 18K White Gold, the vintage Art Deco cluster setting pairs protective 4-claw talon prongs with an ergonomic 2 mm comfort-fit band. Every center stone includes an Official IGI Diamond Grading Report. Proudly Designed in Austin, TX, each ring is custom crafted to order in 3-4 weeks and backed by the GEMNOMADS Lifetime Manufacturer Warranty.

Frequently Asked Questions
How does a 3 carat (3ct) elongated cushion cut lab grown diamond look on the finger?
An elongated cushion cut diamond distributes its 3.00 carat (3ct) weight across a rectangular pillow-shaped footprint, providing broader vertical finger coverage than a traditional square cushion while its calibrated 57-to-58 facet structure eliminates central bow-tie shadows.
Why is solid 18K Yellow Gold popular for this Art Deco cluster setting?
Solid 18K Yellow Gold is our most requested metal for the Harper ring because its rich heirloom warmth contrasts strikingly against the icy Color E, Clarity VVS2 center stone and 0.28 carats of baguette and round side diamonds. It is also custom cast in 18K White Gold or 18K Rose Gold.
Which wedding band styles stack best with this 3.28 TCW Art Deco ring?
Because the geometric baguette and round cluster shoulders taper along the 2 mm band, contoured or chevron wedding bands nest flush against the setting, while a classic straight band creates a timeless vintage gap.
Is this 3 carat cushion cut lab grown diamond IGI certified and custom crafted?
Yes. Every center stone includes an Official IGI Diamond Grading Report with a laser-inscribed girdle number verifying Color E, Clarity VVS2, and Ideal cut. Proudly Designed in Austin, TX, each ring is custom crafted to order in 3-4 weeks and protected by the GEMNOMADS Lifetime Manufacturer Warranty.
