Frequently asked questions

How much do round platinum engagement rings cost?
Prices on Rinderr typically range from $200 to $12,000, depending on the size and quality of the stone, the metal and the jeweler.
Why is the round cut the most popular?
Its symmetrical facets return light very efficiently, which gives maximum brilliance, and its timeless shape suits nearly every setting and style.
Is platinum better than gold for an engagement ring?
Platinum is denser, naturally white and usually hypoallergenic, but costs more. Gold is lighter and comes in more colors. Both are excellent choices.
