Candy coloured gemstones and pastel enamels are the flavour of the season. Apart from the popular big 3, the rocks jostling for the limelight are rose quartz, opals, tourmalines, multi-coloured sapphires, tanzanites, morganites, Russian emeralds, and more. Pops of colour juxtaposed with diamonds, polkis or pearls were hot picks at the recently concluded IIJS Signature.
