Running the finish through the chain as well is what keeps the piece reading as one dark line rather than a dark pendant hung on a bright chain, and the slight reflectivity keeps the milgrain readable instead of flattening it.\u003c\/p\u003e\n\u003cp\u003eSmaller lab-grown ruby marquises form the rays and the point at the base, so the red runs through the whole pendant rather than sitting in one spot. The white accents — the halo of rounds around the frame and the pavé along the upper edge — are cubic zirconia.
