This rose gold heart-shaped morganite and diamond halo ring features an intricate filigree gallery and a sparkling accent band.

Because your ring is rose gold in color, this specific hallmark tells you a couple of important things about its materials:

• It is Rose Gold Plated: The ring is not solid gold. It consists of a sterling silver base metal that has been electroplated with a thin layer of rose gold. 

• The Gems are Likely Simulants: Jewelry stamped with this hallmark typically uses cost-effective simulated stones rather than high-value precious gems. The pink center stone is likely a simulated morganite (such as pink cubic zirconia or glass), and the halo accents are likely cubic zirconia rather than natural diamonds.

• Resale / Retail Value: If sold as secondhand or vintage fashion jewelry, similar rose-plated sterling silver morganite rings typically sell for $50 to $170 on retail platforms like ⁠eBay or ⁠Etsy
