This cushion cut sapphire weighing 6.29 carats has a beautiful spread (looking like an 8.50 carats stone). The hue is a vivid and rich AIGS Type A blue hue especially evident around the girdle perimeter. Owners claim that the stone has been given a 4 Star on the AIGS Sapphire Scale and the undersigned cannot agree more! Encircle the sapphire with round brilliant diamonds and you have the making of a fine sapphire ring fit for a very elegant lady! |
