Bidiamonds is a dedicated platform built to help you make smarter diamond jewelry purchases.
We believe in transparency. Most buyers overpay or end up with smaller diamonds because they don't have access to price comparisons.
Our system allows you to compare offers for any diamond ring, earring or jewelry item — before you buy. We work directly with trusted manufacturers from major diamond exchanges worldwide.
As we monitor market prices, we occasionally discover brands offering truly attractive deals. These are the brands we highlight here.
Some suppliers are also part of our Selected Supplier program. Look for the badge 
next to their name.
