3ct Marquise Lab Grown Diamond Engagement Ring – Platinum Hidden Halo

The client came to us with a photo of a classic six-prong marquise solitaire elegant cathedral band, clean lines, exactly the silhouette she wanted. She loved the elongated shape but felt the design needed more personality, something that would catch her eye throughout the day without overwhelming the center stone's dramatic profile. She asked if we could add hidden sparkle visible only from certain angles, a private detail meant just for her. We designed a concealed halo of round brilliant diamonds beneath the marquise and lined the cathedral shoulders with delicate pavé, preserving the ring's streamlined top view while creating flashes of light from the side. The final piece pairs an E color, VVS2 clarity marquise lab-grown diamond with 14K gold, delivering the secret dimension she requested.
