Lab Rainbow Sapphire

🔹 Color Consistency – Each stone delivers pure, saturated color with no uneven zoning (common in mined sapphires).

🔹 9 Mohs Hardness – Durable enough for engagement rings and daily wear, just like natural sapphires.

🔹 Ethical Rarity – Own "fantasy colors" like electric pink or sunset orange, typically impossible to find in large natural sizes.
