Zircon is a natural gemstone !

Stop confusing this beautiful natural stone with cubic zirconia !

Zircon is a natural stone. It's a zirconium silicate. Initially it's dark brown, green or red and it changes color when heated. Most blue stones are pastel blue, but some exceptional gems have a bright blue color. Zircon is also available in green, dark red, purple, yellow, brown and orange. Due to its high refractive index and high dispersion, zircon has a high gloss and high intensity.

Zircon deposits are mainly alluvial

Zircon is found in Australia, Brazil, Cambodia, Korea, Madagascar, Mozambique, Myanmar, Niger, Sri Lanka, Tanzania, Thailand and Vietnam.

The most popular zircon color is blue. The more intense the blue is, the higher the price will be. The brilliance of zircon is legendary, which makes it possible to use as a diamond substitute when it's colorless.

Do you know about blue zircon?

For lovers of blue stones, this magnificent gem is still practically unknown in France. It's a wise choice because the choice of stones is limited in intense blue tones:
– The famous tourmaline Paraiba (whose prices reach the top)
– The blue topaz (tampered with and irradiated therefore it's best to avoid it ….)
– Aquamarine (paler and less brilliant)

Blue zircon has a high refractive index which gives it an exceptional brilliance (like diamond).
Be careful not to confuse it with cubic zirconia, a substitute of diamond.

Zircon is a naturally occurring mineral called zirconium silicate.
It's one of the oldest stones on earth.
A 4.4 billion years old deposit has been discovered in Australia.
Cambodia and the Ratanakiri mine produce beautiful stones.

Zircon has a good hardness, 6.5 to 7.5 on the Mohs scale but it must be handled with care.


And do not forget, all stones are fragile! even diamond ….

To determine the quality of a stone, color is the most important criterion.
