Platinum Antique Style Oval Diamond Ring vs Antique-Style Diamond Semi-Mount Ring

Buy the Platinum Antique Style Oval Diamond Ring if you want a finished ring you can wear the day it arrives. It pairs a durable platinum band with a large oval center stone and detailed antique styling, and owners of platinum report it holds up to daily wear better than softer metals. Buy the Antique-Style Semi-Mount only if you already have a center stone or want to choose one yourself, since it arrives as a setting with 1 1/4 carats of lab-grown accent diamonds. The trade-off is real: one is complete, the other is a project.

• Choose the Platinum Antique Style Oval Diamond Ring if you want a complete, ready-to-wear platinum ring with an oval center diamond and no further work needed.
• Choose the Antique-Style Semi-Mount if you want to pick your own center stone and prefer lab-grown diamonds in a yellow-gold antique setting.
