These earrings were a disappointment. They are a reasonable size (stone is aprox. 6mm) but the colours are lighter than pictured. Especially the Blue Topaz. They look almost clear. Amethysts are light but you can still tell they are purple and the Peridot colour is fine. But the stones are loose on each and every earring and the metal setting is mis-shapen on two of the pairs. The posts on the pair I received are in the middle, from the other reviews it sounds like the pairs with posts in the corners may be of better quality.  I'd skip this pair and look instead at the cushion cut sterling silver gem stone studs from the Amazon Curated Collection. They are much better colour and quality!
