AI-assisted summary
Description from the seller
Natural Sapphire – 1.44 ct – Oval Mixed Cut – Deep Blue (Greenish) – Heated – ALGT Cert.
This is a natural sapphire of 1.44 carats, cut in an oval mixed cut that offers a classic outline and a balanced face-up. The stone has a refined appearance with good transparency and a strong presence for its weight.
The sapphire displays a deep blue color with a subtle greenish modifier, creating a moody, sophisticated tone that is highly attractive in darker sapphires. The clarity is good for this type, showing typical minor inclusions that do not detract from the overall appearance. ALGT notes indications of heating, the standard and widely accepted enhancement for sapphires to improve color and clarity.
Nicely proportioned at 8.11 × 6.31 × 3.10 mm, the stone faces up with rich color concentration and even saturation. This sapphire is well-suited for a fine ring, pendant, or as part of a curated gemstone collection.
