What more fitting stone for the spirit of night, than a somewhat bat-shaped pattern for dark grey smoky quartz? The pavilion is very straightforward; the crown has two mirror meets that may make things a bit complicated, but it should be doable. Works in any material from feldspar to CZ (RI = 1.52 - 2.16) with no changes. Suggested size = 10-15 mm
