Bangkok Blue Sapphire (Neelam) — 2.85 Carat (3.13 Ratti), Oval Mix Cut
Photos: This oval mix SKU uses the standard (non-square) set — close-up, back, and in-hand. The square-crop files in the same folder belong to the octagon mix 2.85 ct listing (Product 03).
This is a Bangkok Blue Sapphire (Neelam) — natural blue corundum (Al2O3), 9 on the Mohs hardness scale for the mineral host. Natural blue corundum is processed through Bangkok — the world’s leading hub for professional sapphire treatment and trading for decades. Skilled treatment routinely uses heat to develop or stabilise blue colour in natural sapphire. This stone additionally carries glass-filling enhancement — a trade-recognised process that improves apparent clarity by infilling surface-reaching fractures, giving a deep, rich navy-blue face-up look at an accessible price point.
Treatment disclosure (our standard practice): The stone is heated, treated, and glass-filled — stated clearly as responsible sellers should. Heat treatment of blue sapphire is very common in the global trade. Glass-filling is a separate, stronger enhancement typical of this budget tier; it is how such stones reach this Rs. 800/carat value level while still being natural corundum.
Astrological / traditional use: In the Indian market, Bangkok Neelam is widely sold and worn as blue sapphire (Neelam) — the gemstone traditionally linked to Shani (Saturn) in Vedic culture. Suitability depends on individual birth charts (lagna, Saturn placement, dasha, etc.); we recommend consulting an astrologer you trust. If your guide requires unheated, untreated material, see our natural African blue sapphire range.

Care Instructions
Clean with lukewarm water, mild soap, and a soft brush only. Avoid ultrasonic and steam cleaners. Always inform your jeweller that this stone carries glass-filling enhancement before any repair, resizing, or torch work. Keep away from strong acids, alkalis, and sudden hard impact.
Setting Recommendations
Ideal for rings, pendants, and men’s jewellery. A bezel or partial bezel helps protect the girdle for daily-wear rings. Prong styles are common for pendants and occasional wear.
Wearing as Neelam (traditional guidance)
Blue sapphire (Neelam) is traditionally considered one of the stronger gems in the Navratna system, linked to Saturn (Shani). In common jeweller and buyer practice, it is often discussed for Saturn-related remedies and for natives with emphasis on Makar (Capricorn) or Kumbh (Aquarius) rashi in their chart context — but only your astrologer can say if this stone suits you. Many traditions suggest observing a short trial period (often around three days) and professional guidance before committing to daily wear. Metal, finger, and day are traditionally chosen with an astrologer’s advice (e.g. silver or panchdhatu, middle finger, Saturday — when recommended).
