While Christmas shopping, I chose a gold ring set with stones for my mother.

A ring set with 2 rubies and a diamond would have cost £3,000. One set with 4 amethysts and a diamond would come to £2,000. And 3 emeralds, 1 amethyst and a diamond would be £1,400.

Being a thoughtful son, I chose a ring that would have sentimental value. As my mother called her children Ellen, David, Richard and Andy, I have chosen a ring with one of each stone, to represent her children's names.

How much will my ring containing 1 emerald, 1 diamond, 1 ruby and 1 amethyst cost me?

Hint

Finding the cost of each gem is not possible. It is still possible to find the value of the ring.
