Single row cz diamond comfort fit band in gold

That is a classic, elegant piece! Based on the images you provided, here is a breakdown of the style and features of this ring.

​Ring Profile & Design

​The images show a channel-set eternity or semi-eternity band. This specific setting is popular because it protects the edges of the stones, making it ideal for daily wear.

​Setting Style: The Cubic Zirconia (CZ) stones are tucked between two parallel walls of metal (the "channel"), creating a smooth surface that won't snag on clothing.

​Band Shape: This appears to be a Comfort Fit band, meaning the interior of the ring is slightly domed/rounded rather than flat. This makes it much easier to slide over the knuckle and more comfortable for long-term wear.

​Metal Finish: While you mentioned it is "in gold," the photos show a white gold or high-polish silver-tone finish. If it is gold, it is likely 10k or 14k White Gold, or potentially gold-plated over another metal.
