Detailed Product Description
This Natural Irani Firoza (Turquoise) Stone weighs 34.23 carat (37.62 ratti) and measures 30.00 x 16.90 x 12.20 mm, with a sky blue colour and an oval shape. It comes with a lab report from The Standard Gem Testing Laboratory, which identifies it as natural turquoise.
Turquoise, known in India as Firoza, is a porous, opaque hydrated copper aluminium phosphate whose colour ranges from blue to green. Irani Firoza, also called Persian turquoise, refers to turquoise from an Iranian source. Iranian turquoise is traditionally known for an even sky blue colour with little matrix, and Irani Firoza has long been the familiar name for Firoza in India, but each stone's value depends on its own colour, matrix, texture and weight. Because turquoise is naturally porous, most turquoise on the market is stabilised (impregnated with a clear resin or polymer) or waxed, which gives a smoother, shinier finish, and a laboratory detects these treatments with its instruments; every Ratna Gems Firoza comes with its own lab report.
Appearance
Cut in an elongated oval outline, this stone displays a prominent, well-rounded high cabochon dome with excellent height. It presents a vibrant sky blue hue complemented by a smooth polished sky blue surface with subtle natural tone variations and host rock on the base. Turquoise is evaluated on colour, matrix character, and surface texture; the accompanying photos and video present this exact stone under neutral lighting so you can inspect its proportions, polish, and natural markings with full clarity.
Traditional Use
In Vedic astrology, Firoza is a traditional upratna, or substitute stone, for Yellow Sapphire (Pukhraj), linked with Jupiter (Guru); some traditions also associate it with Ketu. Customers buying it for astrological use usually follow their astrologer's guidance. Turquoise is also known as a December birthstone.
Care
A few easy habits keep turquoise looking its best. Wipe it with a soft dry or slightly damp cloth and dry it at once, put it on after cosmetics and perfume, and take it off before washing, cooking or swimming. Turquoise is soft, about 5 to 6 on the Mohs scale, and porous, so skip soaking and steam or ultrasonic cleaning, and keep it away from perfume, lotions, cosmetics, oils, acids, solvents, other household chemicals and high heat. Pendants and earrings take fewer knocks than rings; in a ring, choose a secure setting. Store it apart from harder gemstones, and let your jeweller know it is turquoise before any setting or repair.

Frequently Asked Questions
Is this Irani Firoza natural?
Yes. Your lab report from The Standard Gem Testing Laboratory identifies it as natural turquoise and records its carat weight of 34.23 Carat (37.62 Ratti), dimensions of 30.00 x 16.90 x 12.20 mm, sky blue colour, oval shape, refractive index, specific gravity, and hardness. Because turquoise is naturally porous, most turquoise on the market is stabilised or waxed to protect the surface, and a laboratory verifies these characteristics with its instruments.
What does Irani or Persian Firoza mean?
Persia is the historic name of Iran, so Irani Firoza and Persian turquoise both refer to natural turquoise originating from Iranian deposits, traditionally celebrated for an even sky blue colour. The gem trade also uses the term 'Persian blue' as a descriptive shade name for turquoise mined elsewhere, so neither name represents a quality grade. The lab report verifies this stone as natural turquoise. It is of Irani origin.
How can I tell natural Firoza from imitation turquoise?
The only dependable way is through a laboratory report from an independent gemological testing facility, and every Ratna Gems stone includes its own physical report. Common market simulants like dyed howlite, dyed magnesite, resin-bonded reconstituted block material, and synthetic glass or plastic are readily separated by gemologists using refractive index and specific gravity testing. This stone's report confirms genuine natural turquoise.
Can this Irani Firoza be set into a daily-wear ring or pendant?
Yes. With dimensions of 30.00 x 16.90 x 12.20 mm and a calibrated oval cabochon cut, this stone is excellently proportioned for a custom jewelry setting. Because turquoise has a Mohs hardness of 5 to 6 and natural porosity, a bezel setting that protects the stone's edges is recommended for rings. It should be kept away from harsh household chemicals, perfumes, and high heat.
