In fact blue gemstones with good hardness and brilliance are rare in nature, which drives the price up. However topaz, a silicate mineral of aluminium and fluorine, is plentiful. Natural topaz is usually colorless (also called "white") or brown. A London Blue Topaz is created by treating a white topaz with radiation. The radiation changes the color centers in the crystal, affecting the way it absorbes light, and thus producing the deep blue color. A blue topaz can come in a range of shades from light to medium to dark, referenced in the industry as: "Sky Blue," "Swiss Blue" and "London Blue," with the latter being the most saturated and valuable.
Sooo what makes a London Blue Topaz so popular are 4 attributes: it’s brilliance, hardness, color and price.
The lovely blue stone caught my eye after I found myself brownsing at some very dark and pricey sapphires recently. That's when it hit me how gorgeous the London Blue Topaz pieces were in the neighboring showcases. Consider this: A top quality London Blue Topaz is much more affordable than a mid quality sapphire.
Moreover, it's a lasting precious stone in a dazzling shade of coveted blue. Beauty and durability for less, not only a feast for the eyes, but music to a Savvy Shoppers ears!🎶🔷👂
