Is the blue topaz in these necklaces natural or treated?
Treatment is standard for blue topaz in general. Most blue topaz on the market starts as colorless topaz that is heated or irradiated to bring out blue. The result is stable, durable color. The shades here range from sky blue to deeper blue, so pick the depth you like best.
What is the best blue topaz necklace for everyday wear?
A single bezel-set stone is the easiest to wear daily. The metal wraps the edge of the stone, which helps protect it from knocks. Topaz is hard, and sterling silver chains suit a 16 to 18 inch length that rests near the collarbone. Take it off before swimming or cleaning. See jewelry care.
What affects the price of blue topaz necklaces?
Stone size, accents, and metal drive the price. Larger or deeper blue stones, diamond accents and their carat weight, and gold versus sterling silver all change it. Chain length and design complexity matter too. Use the Price filter on this page to set a budget.
Which blue topaz necklace styles are most popular?
Simple stone necklaces in sterling silver lead the list. Round, cushion and oval blue topaz styles come first, many with an antiqued finish, followed by diamond and blue topaz pairings. Accent styles, a cross, and a heart also appear among the top picks. Most are 18 inches long.
