The Hollywood Collection has been around for a fairly long time now, and initially began by offering reproductions of jewellery worn by celebs (mostly in the golden age of Hollywood) in cubic zirconia and sterling silver.
This ring is noted as being part of their Marlene Dietrich collection, though I don’t see any attribution to one of her films or to her personal life. Dietrich had a fabulous collection of fine jewellery she wore to premieres, red carpets and just because. Trashy starlets of today, take note.
Regardless, this ring is quite pretty and wearable. It features a 3 carat oval simulated ruby surrounded by round cubic zirconia stones, set in rhodium plated sterling silver. It sells for USD $75.
