Please help : Antique vase : info

[ods 10]

I would like to have more info on these two vases. They are identical in size which is 28cm high and 12cm in diameter. The pattern of roses is not quite the same. These vases are from Diamond Pottery, Hanley, England which existed during 1908-1935. There are a few very fine hairline cracks. Overall in a good condition. Has anybody seen these vases before? What will it be worth?
