Are Swiss blue topaz necklaces real or treated?
Swiss blue topaz is a real gemstone, but the color is treated. Natural blue topaz is pale, so most blue topaz on the market is colorless topaz that has been irradiated and heated to reach its blue. This is the standard, stable process for the stone. The page does not state whether these stones are natural or lab-created.
Which Swiss blue topaz necklace styles are most popular?
Simple single-stone styles lead the list. Light antiqued, teardrop and round Swiss blue topaz necklaces in sterling silver come first, followed by a round cross and peridot pairings. Emerald-cut, cushion and heart styles also appear near the top.
How do I choose between a round, teardrop and cushion stone?
Pick by how much presence you want. A round stone is the most understated for daily wear. A teardrop adds a longer line toward the collarbone, while a larger bezel-set cushion shows the most blue. Browse Swiss blue topaz pendants to compare more shapes.
How do I care for a Swiss blue topaz necklace in sterling silver?
Wipe it gently and store it dry. Topaz is hard, but sterling silver can tarnish, so use a soft cloth and keep the necklace apart from other jewelry. Avoid harsh cleaners. Antiqued finishes are best polished lightly so the darker detail stays. See our jewelry care page.
