Diamond Jewelry price comparison

Buying diamond jewelry in the US: your questions answered

How do I choose diamond jewelry?

Decide the shape and carat weight first, then compare cut, color and clarity grades — cut has the biggest effect on how a diamond looks, and a slightly lower color grade is often invisible once set. Always check the grading report and the setting metal. The same specification can differ by thousands of dollars between authorized US jewelers, so compare the live prices here before you commit.

Where is the cheapest place to buy diamond jewelry online?

There is no single cheapest retailer — it changes per product and per promotion. We check each product against every US retailer in our feeds and show the lowest total, including delivery where the retailer publishes it, so the cheapest shop is whichever one is winning on that item today. You can also set a price alert and we will email you when a product drops.

What types of diamond jewelry can I compare here?

This department is split into rings, engagement rings, wedding rings, necklaces, earrings, bracelets and pendants. Use the filters and sorting on this page to narrow by type, then sort by price to see the cheapest live option first.

How often are diamond jewelry prices updated?

Retailer feeds are re-imported through the day, and we log every price change with a timestamp so each product card can show its recent price history rather than just today's number. If a retailer stops sending updates we flag it instead of showing a stale price.
