White Topaz – $50,000/Kg

Due to its affordability of just $10 per carat and clear appearance, white topaz has gained popularity as a second-best alternative for jewelry lovers who cannot afford diamonds. When free of impurities, white topaz is transparent. The gem, like every other, typically has internal imperfections, including spots and twines. These flaws would, however, be less visible in a smaller stone than a bigger one.

It is, however, essential to note that you get what you pay for. So, as you pick it out, you should be aware that compared to the more expensive types, this stone is more prone to scratches and losing the vibrance of its appearance over time.
