Through the gemstones panel, which you can access here:

You can share your referral link directly with a friend via Facebook, X, or email. You can also copy and paste the referral link into other social media platforms, SMS, WhatsApp, etc.

Once your friend clicks on the referral link, they will be redirected to the store's page; where they'll have to enter their email address in a prompt to get their reward/discount code via e-mail. Your friend will need to manually copy and paste the code for it to be applied at checkout.
When your friend makes a purchase with the reward/discount code, the referral is considered completed. Only then will you receive an email notifying you that your friend has made a purchase with your reward/discount code. You can find this by logging into the store and clicking on the panel > Your rewards.
