For some of you that love to work with wire there is a sight called wire-sculpture.com that will email you a tip of the day on jewelry making. Here is todays tip:
Many of your gems are sized in mm. Is there a formula for determining the amount of carets a gem has?
All gems are sized in mm's. Each gem has a different chemical structure and the weight of each gem is dependent on it's chemical structure, therefore, there is no formula that equates weight to size for different gems.
