Our take on the Luna Lab Grown Diamond Engagement Ring Elongated Radiant - 14K Yellow Gold

The Luna is a solitaire engagement ring built around an elongated radiant-cut lab grown diamond in 14K yellow gold. The cut is the selling point: an elongated radiant gives a step-cut look with brilliant-cut sparkle, and its stretched outline makes the stone read larger on the finger than a round of the same carat weight. It suits shoppers who want a modern, clean-lined solitaire and are comfortable with a lab grown stone. Against round and oval solitaires it trades the classic shape for something less common, and against halo settings it stays simpler and easier to keep clean. Buyers rate it 4.9 out of 5 across 120 ratings.

Questions and answers

Is a lab grown diamond a real diamond?
Yes. It is chemically and optically the same as a mined diamond, just grown in a lab. It will test as a diamond on standard testers.
How does an elongated radiant cut compare with an oval or round?
It has the stretched outline of an oval but the faceting of a radiant, with more step-like flashes than a round brilliant. It looks larger per carat than a round.
Will the stone sit high on the finger?
The solitaire setting holds the stone above the band, so it sits proud. Buyers who work with their hands often prefer a lower-set ring.
What is in the box?
The ring itself. A matching wedding band is not included and would need to be bought separately.
Can it be resized?
A plain 14K gold solitaire band can usually be resized by a jeweler. Have it sized before wearing, since repeated resizing stresses the band.
Does a lab grown stone hold resale value?
Less than a mined diamond of the same size. Treat it as a piece to wear, not an investment.
