The outline of the selenite grid plate comes from a grid-marked form; long mineral bands and changes in transparency across the broad face remain part of the finished look. The recorded dimension of 8cm describes the general scale of the grid plate.Product details Material: Selenite Colour: White and gold Approximate size: 8cm Finish: Polished surface Design: Grid-marked form Place the plate on a flat display surface with nothing heavy above it and make sure nothing wet is placed above the stone. The selenite grid plate works best on a dry shelf with space around the shape to reduce knocks during cleaning and tidying. Give the selenite grid plate enough room that it can be lifted easily to reduce unnecessary handling.Individual markings: One the grid plate may look clearer than another, especially when comparing the direction of long bands across the broad face. Small natural marks can remain on the grid plate after finishing and are not signs that it has been used.Keeping it in good condition: Use a dry method for the grid plate: support the underside while wiping from the centre towards the edge; keep every part of the stone completely dry. To reduce scratches and small chips, store the grid plate away from wet cups, plant pots and sinks rather than placing it in a damp room or busy drawer.
