The Luna pairs a lab-grown center diamond with a 3.00mm U-pavé band and round brilliant lab-grown diamond accents. The open U-pavé structure brings light into the side stones for a luminous profile.
Complete engagement ring with center diamond included. Select your in-stock metal, center-diamond weight, and current US ring size below.
Ring sizing: the listed size is the current finger size. Ring size can generally be adjusted one to two sizes up or down, subject to our jeweler confirming the design and requested fit. Resizing may affect dispatch timing.
Radiant or Emerald: either center shape is available for selections carrying this label. Add your preferred shape to your order notes or contact us before ordering. These choices use the same in-stock ring, so availability is shared. We will confirm the selected stone and any setting time before dispatch.
Need it quickly? Select rings can ship the same business day after payment, sizing, and final inspection are complete. Two-day shipping is usually available after dispatch; next-day delivery can be arranged on request. Some in-stock designs require center-diamond selection and setting before dispatch. Contact Classic Jewelers before ordering to confirm your deadline, destination, shipping cost, and dispatch date.
Center weights below are the recorded center-diamond sizes and exclude side stones. Product photographs show the design; center proportions, metal appearance, and pavé coverage may vary with the selected configuration. Contact us for photographs of the exact ring.
