Comparisons
Most people arrive already down to two names. These pages settle it on published terms, imaging approach, ownership and what each is actually built for.
Check live prices — we don't print them here, because they change daily.
Rings
The centre stone is where nearly all the money goes. Compare the same specification at each — shape, carat, colour, clarity, cut grade and grading laboratory held identical, or you are not comparing anything.
Earrings
Sold by total carat weight across the pair, so a 1ct pair is two half-carat stones. Cheap enough to make a sensible first purchase from a retailer you have not used before.
Bracelets
Check the clasp and the safety catch before the stone quality. A tennis bracelet that springs open on the wrist is the most common way people lose one.
Necklaces
The chain matters more than buyers expect. Check the gauge and the clasp — a heavy pendant on a thin chain is a repair waiting to happen.
Links open each retailer's own category page. Rare Carat links are affiliate links and earn us a commission if you buy, at no extra cost to you. The others are plain links that earn us nothing today. If that changes, this line changes with it. Every relationship is listed on the disclosure page.

Still to publish
Next in priority order, set by search demand against difficulty:
- Zales vs Kay vs Jared — the three-way
- Ritani vs Blue Nile
- Costco vs Blue Nile
- Brilliant Earth vs Ritani
- Angara vs Blue Nile
- James Allen vs Rare Carat
- Brilliant Earth vs Shane Co
Each of these sits at or near zero difficulty with paid competition well above the site average. One page serves both word orders — put each phrasing in the title and a subheading.
