My guess is that the description from Fields is not quite right. The proportions of the heart shape stone, the smaller stones, and the pearls are identical. In the original necklace there are no stones that could be used as pendants and the small amethysts are not framed in diamonds. Only the center stone had the diamond frame. Since the Duchess of Cornwall has worn other jewels from the Queen Mother it would make sense that her necklace is this one, from the Queen Mothers collection.
