Invisible setting is a new and improved setting method that is considered as one
of the most difficult setting methods. In this setting, the stones are positioned
in such a manner so that metal is not visible from in-between stones that ultimately
show appearance of uninterrupted and continuous surface. In this setting, stones
are grooved just below the girdle and then those grooved stones are slid onto metal
tracks to hold them in place.
This setting is appropriate only for multi-stone arrangement that usually attached
in multiple rows. It looks similar to pave setting but gives better look and more
brilliance, since no claws obstruct the light's entry. Usually invisible setting
is best suited with square princess, emerald, baguette, and trillion cut diamonds
and gemstones because the straight edges can be positioned very close to each other
without leaving any space in-between.
