发明名称 Butterfly gem
摘要 A cut stone having a crown (21) and a pavilion (23), the crown having peripherically four indents orientated face to face and forming a cross, the apparence of the crown of the stone forming a butterfly. The crown defines centrally a table in the shape of a reversed trapeze surrounded by facets defining two wings located toward the outside of the trapeze. The pavilion (23) comprises a number of facets distributed according to orientation angles combined to create a void of brilliance in the area of the indents. Under the table of the crown appears the reflection of the pavilion which uncovers two flapping wings located internally; the flapping wings added to the two wings at the exterior of the trapeze, give the appearance of a lepidopter.
