Blue Gemstones: Neelam, Beruj, Feroza and More نیلا
In short: Our natural blue stones are Neelam (blue sapphire), blue topaz, Beruj (aquamarine), tanzanite, Lajward (lapis lazuli) and Feroza (turquoise). The first four are transparent and faceted; lapis and Feroza are opaque and usually cut as cabochons. Hardness, depth of colour and treatment set them apart, and we disclose dyeing and stabilisation.
We carry six natural blues: Neelam (blue sapphire), blue topaz, Beruj (aquamarine), tanzanite, Lajward (lapis lazuli) and Feroza (turquoise). The first four are transparent and faceted. Lapis and Feroza are opaque and are usually cut smooth. What separates them is hardness, how deep the blue runs and how they have been treated.

| Feroza | 5–6 | Opaque sky blue to green-blue, may show matrix | Often stabilised |
Before you buy
- Neelam: look for even colour with no dark patches, and ask whether it is heated, especially if you are buying for astrology.
- Blue topaz: the colour comes from treatment and is stable. It should never be passed off as sapphire.
- Tanzanite: protect it from knocks and keep it out of ultrasonic cleaners.
- Lapis and Feroza: rub gently with a damp white cloth; dye sometimes comes off. We state dyeing and stabilisation on the listing.
Paying Cash on Delivery means you open the parcel in front of the rider and check the stone before handing over any money. You are also free to have it tested at an independent lab.
What makes one blue stone worth more than another
With Neelam, the best is a pure, medium-deep blue that stays lively under indoor light, and unheated stones fetch more. Blue topaz and aquamarine are judged on clean clarity and a stronger blue. For lapis, look for an even royal blue with very little white calcite. You can browse by budget with our mid-range filter or the other ranges on the shop page.
