Abstract : Synthetic quartz crystals are traditionally grown from a crystalline nutrient. Most of the present crystal growth is from natural quartz nutrient imported from Brazil. This material is handpicked for quality but does have limited purity levels. The raw material may or may not contain levels of impurities that are detrimental to the intended purpose of the grown crystal. Impurity concentration and species of natural lascus are not uniform or consistent even when produced from the same source of supply.
