The value of a precious stone is determined by its gemological makeup, natural rarity and finished quality. Diamonds and gemstones of similar appearance can have important differences in value. Few independent laboratories like Gemological Institute of India (GII) offering certification have techniques to provide expert and impartial analysis of a jewellery’s precious stones, specifying carat weight, colour, clarity, natural origin etc. without disassembling the jewellery piece. At CarbonDrops we ensure every piece of jewellery is certified by GII or any other equivalent Labs.
