Here's a photo of one vase taken on my phone which shows the colour better I hope. Yes the pattern on them is swirls rather than floral and having had a look online definitely classical Greek in style. I've seen very similarly decorated vases like the bottom pair online attributed as being French, possibly even Baccarat, or as Bohemian. I've even seen some for sale in Finland which came out of Russia and are said to be Russian made. Considering the influence French culture had with in the Russian royal court in the late 1800's I think it's much more likely they were French.
