*Detailed Description*:
This 3.00 ct unheated Ceylon sapphire hits the important 3 ct mark — a key weight for collectors and investment. Sri Lankan blue sapphires are legendary for their pure, vivid blue with subtle violet flashes. The color is bright and lively, not dark or inky, which is why Ceylon blue commands global prestige.
At 9.1 × 6.6 mm with 5.6 mm depth, this elongated oval has excellent proportions. The depth holds color beautifully and prevents windowing, giving it strong face-up presence. “Slightly Included” is normal and desirable in unheated sapphire — fine silk or tiny crystals prove no heat was applied and don’t impact beauty. In fact, collectors prefer light silk in unheated stones.
No Heat is the rarest category — less than 2% of sapphires are gemmy with natural color and no treatment. Unheated Ceylon blue carries a 40–70% premium over heated because the color is 100% as nature made it. Hardness 9 makes it perfect for daily-wear luxury. September birthstone and 5th/45th anniversary gem.
*Perfect For*: Heirloom engagement rings, investment-grade collector pieces, high-jewelry earrings, September birthstone, legacy jewelry
*Unheated Ceylon Sapphire Highlights*:
- No Heat = top rarity tier — certified natural color, no enhancement

*Price Context*: Unheated Ceylon blue 3 ct, SI to eye-clean: $1,500–$4,000/ct depending on color grade. This 3.00 ct would retail $4,500–$12,000+ with cert. Unheated premiums are rising 8–12% annually due to scarcity.
*Care*: Extremely durable. Clean with mild soap, water, soft brush. Ultrasonic/steam safe. Store separately to avoid scratching softer gems
