The nine stones consist of diamond, pearl, coral, hessonite, blue sapphire, cat's eye, yellow sapphire, emerald, and ruby in its center, as it is associated with the Sun.

Some of the most expensive gemstones available in Delhi include Kashmir Sapphire, Burmese Ruby, Colombian Emerald, Pink Diamond, Red Beryl, Paraiba Tourmaline, Alexandrite, and more. These gems, known for their rarity, exceptional beauty, and enduring value, command high prices in Delhi's gemstone market.
