• Advantage: Using a common prong minimizes the amount of metal between the gems and directs maximum light to the bottom and sides of the gems. This maximizes the fire and brilliance of the diamond and makes the gems appear larger.

• Back structure:

• Purpose: These holes are designed to allow maximum light to enter the lower part (Pavilion) of the diamonds and also to facilitate cleaning the gem.
