Platinum Engagement Rings

If you want to design an engagement ring that will last as long as your love for one another, choose platinum. Platinum engagement rings are the most popular choice at Blue Nile, because they provide a white sheen that reflects the brilliance of the diamond. This incredibly durable material means the engagement ring you design will last a lifetime. Shop platinum engagement rings at Blue Nile, and propose in sparkling style.

FAQs about Platinum Engagement Rings

White gold offers a similar white sheen, making it a popular alternative to platinum. White gold is not as durable as platinum, making it more susceptible to scratches over time. In fact, white gold features a layer of alloy rhodium (a precious metal from the platinum group) and will require occasional plating.

The material of the band, cost of the stone, and details of the setting are a few of the factors that go into determining the final cost of an engagement ring.

On average, Blue Nile customers select a diamond just under one carat, but you can choose any size that fits the setting and budget you select.

Because they stack directly on top of one another, we recommend choosing the same type of metal for both the engagement ring and the wedding band. Because the wedding band and engagement rings are stacked, it's important to choose designs that complement one another. Otherwise, the band of one could scratch or damage the band of the other with daily wear.

Platinum Engagement Ring with Princess Cut Diamond Review

Very Satisfied

From Him: I shopped around for a while from bricks and mortar stores to other online options but kept coming back to Blue Nile for the ring selections along with the diamond pricing. I ultimately settled on a Hand-Engraved Micropavé Diamond Engagement Ring in Platinum (1/6 ct. tw.) with a 1.91 ct princess cut diamond. From Her: Stunning ring! Platinum is absolutely beautiful, and the diamonds and style of band is unbelievably sparkly!! The ring was too big and had to be sent back for resizing and it was so hard to be without it – I think any ring this would be the case! I continue to get compliments on how sparkly and beautiful this ring really is.

Platinum Engagement Ring Review

The quality is beyond expectations

I have been an admirer of Blue Nile for many years. It wasn’t until I found the right woman that I decided to purchase from Blue Nile. Upon arrival, I was greatly impressed by the presentation box; then I opened the ring box. The brilliance of the diamond is breathtaking and the luster of the platinum is extremely pleasing. My fiancée is absolutely in love with the ring and has a hard time not staring at it. Thank you Blue Nile for helping me and being there for me when I needed the best.
