Deep royal blue takes the classic royal blue and pushes the saturation even further. These are the sapphires with serious presence, dark enough to command attention but still transparent enough to show life and brilliance. Think midnight blue with a velvet texture. We source them from partner mines in Sri Lanka and Madagascar. Direct, no middlemen. The challenge with deep blues is finding stones that don't go "inky" or opaque in lower light. The best ones maintain their glow even indoors. These are popular with collectors who want maximum visual impact on the finger. Unheated specimens are particularly sought after.
