Sky, Swiss and London blue, in one stone
Blue topaz necklaces feature blue topaz, topaz treated to display clear blues in three trade shades: pale Sky Blue, vivid medium Swiss Blue, and deep, slightly grey-green London Blue. Natural blue topaz is rare and very pale, so nearly all blue topaz jewelry is produced by irradiating and heating colorless topaz, a standard, stable and accepted treatment that sellers disclose. This guide covers the three shades and how to choose between them, topaz properties, including its hardness and the cleavage that calls for protective settings, pendant, strand and station necklace styles, metal pairings, and care. Blue topaz is a December birthstone and one of the most affordable ways to wear a large, clean, strongly colored blue stone at the neck.

The blue topaz shades let a buyer tune a necklace precisely. Sky Blue pendants sit quietly against the skin and pair with silver for a fresh, daytime look. Swiss Blue is the crowd-pleaser, bright enough to register across a room and the shade most station necklaces and strands are built in. London Blue does something rarer: a deep, muted blue that behaves almost like a neutral, wearing well with black, grey and evening colors where a brighter stone would shout. Owning two shades is common in necklace collections for exactly this reason.
Settings should respect topaz cleavage: bezels and halos protect the girdle of a pendant stone, and prong settings should use enough metal to guard the corners of emerald and cushion cuts. White metals keep all three blues clean, while yellow gold warms Sky and Swiss shades into a deliberate contrast. With honest treatment disclosure and a sound setting, a blue topaz necklace offers more saturated blue per dollar than any other stone in the necklace section, which is why it anchors so many colored-stone pendant collections.
They are three depths of the same treated blue. Sky Blue is pale and airy, close to aquamarine in effect. Swiss Blue is a bright, saturated medium blue, the most electric of the three. London Blue is the deepest, a steely blue with slight green-grey tones that reads as sophisticated and suits evening wear. Price rises modestly with depth, and the choice is mostly about the wearer's coloring and how strong a blue statement the necklace should make.
Yes: almost all blue topaz is colorless topaz that has been irradiated and then heated to develop a stable blue. The treatment is permanent in normal wear, is universally accepted in the trade, and should be disclosed. It does not make the stone fragile or artificial; the material is genuine topaz throughout. Buyers are paying for color, cut and setting quality, and treated blue topaz delivers all three at prices natural blue stones could never reach.
Topaz is hard but has perfect cleavage, so protect pendants from hard knocks and avoid ultrasonic and steam cleaning. Clean with warm soapy water and a soft brush. Long exposure to strong heat is best avoided, and store blue topaz away from harder stones. Check prongs on pendant settings regularly, since a topaz pendant's size gives it leverage, and keep the chain and clasp in proportion to the stone's weight.
