Dear Malvika,
You have given your DOB  so it is easier to recommend you favourable gem but for your husband and son you had to give their respective DOBs and TOBs and also POB.
The gem for the fifth lord is particularly lucky, while also being good for creative energy, and children. Your fifth lord is Mercury, therefore wearing Mercury's stone will be beneficial. The stones for Mercury are : Emerald, Peridot and Jade.      “The emerald is cool, good in poisoning, sweet and purgative, helps digestion, cures biliousness, removes disrelish, is nutritious, and wards off spectral influence.”
Wearing instructions: The gem for Mercury is best set in gold. If a ring, it should be worn on the small (pinkie) finger. Begin to wear it on a Wednesday, two hours after sunrise. The gem for the ninth lord particularly brings fortune. Your ninth lord is Saturn, therefore wearing Saturn's stone will be beneficial. The stones for Saturn are : Blue Sapphire, Blue Spinel, Lapiz Lazuli and Amethyst.      “The (Blue) sapphire is bitter, warm and good in cold and biliousness, and alleviates the rage of Sani (Saturn) when worn.”
Wearing instructions: The gem for Saturn is best set in gold, alternately iron can be used. If a ring, it should be worn on the middle finger. Begin to wear it on a Saturday 2 hours and 40 minutes before sunset.       Generally it is always best to purchase the best quality gemstones that you can afford. The stones of lesser potency have been found to work very well and are less costly, though they need to be worn in a larger size in order to give the same strength of effects.      To derive the best effects of a gem, begin to wear it after cleansing it in fresh milk and rinsing it in purified water. Then, holding and concentrating on the gem, perform the mantra given 108 times.      Gems should generally be worn on the right for men and the left for women. Gems may be worn either on the appropriate finger as a ring, or on the upper arm as a bangle. Alternately the gem can be worn around the neck, but this has the disadvantage of the gem swinging and not maintaining skin contact. Most important is that the Gem is set so as to touch the skin.
