What are gemstones?
Gemstones (also known as precious or semi-precious stones) are minerals found in various forms cut and polished, used to make jewelries.Most gemstones are hard, rare and expensive. These are cut into different shapes and sizes for jewelrymaking. They are also graded based on their colours, shapes, sizes which in turn affects the price. Examples are pearls, diamond, corals, ruby etc.
For instance, crystals come in different grades(qualities) with the best quality being swarovski crystals. Next to that is the czech crystals followed closely by chinese crystals. The higher the quality, the longer the shine, colour beauty and sparkle!
