This stone somehow captures my attention with its imperfections.
For the size of 8.7 carats and measurements of 14 x 0 x 7mm is it worth 200 USD?
What about I be looking out for when purchasing bi coloured or multicoloured tourmalines? What colours are more valuable and are the one with straughter and cleaner gradients more expensive too?
