SUPER SEVEN-CRYSTAL RING This is a natural untreated stone from Brazil it is very well polished. There are strong golden needles in this stone. The workmanship and quality is excellent. Sterling silver Stamped 925 Weight of stone and silver: 25.94 cts app Our jewellery manufacturing is contracted out to one factory in Asia where I supply both the silver and stones to be set. This gives me control of the quality of both the silver and stones. Super Seven is a rather interesting crystal, also known as Sacred Seven and Melody’s Stone. Although not always visible a piece of Super Seven retains all the properties of Amethyst, Clear Quartz. Smoky Quartz, Cacoxenite, Rutile, Geothite and Lepidocrocite combined. This is part of what makes this stone so desirable. However what gets people really excited is that it is one of the few stones that retains all the energy and clarity of each mineral and it never needs cleansing or energising!
