Stones and their numbers
Each number carries a planet and each planet a stone: ruby for the Sun, pearl for the Moon, yellow sapphire for Jupiter, hessonite for Rahu, emerald for Mercury, diamond for Venus, cat's eye for Ketu, blue sapphire for Saturn and red coral for Mars. The driver number's stone is the main one, the conductor's supports it, and a missing number's stone is sometimes added to cover a gap.
Stones for wealth and for love
Money is traditionally ruled by Saturn, Venus and Jupiter, giving blue sapphire, diamond and yellow sapphire. Love and marriage are ruled by Venus, the Moon and Jupiter, giving diamond, pearl and yellow sapphire. The right pick depends on your own chart, because a stone belonging to a number hostile to your driver is avoided no matter how well it suits the goal.
Buying without being cheated
This is the part of numerology where people lose real money. Buy only certified, untreated stones from a dealer who will put the certificate in writing, and start with the substitute rather than the premium stone. Have the weight decided by a practitioner who is not selling you the stone, since the shop always has a reason to recommend a bigger one. Gemstone effects have no scientific evidence behind them, so spend at the level you would spend on jewellery you simply like, and never in place of medical treatment.
Stones are one remedy among several; the remedies page covers the free ones.
