FAQ

What is Santa Maria Aquamarine? 

Santa Maria Aquamarine refers to the finest colour grade of aquamarine, known for its intense, saturated blue hue with minimal green tones.

Why choose an octagon cut for Aquamarine?

An octagon cut is an excellent choice for aquamarine because it:

For Santa Maria aquamarine, the octagon cut helps showcase its rich blue colour while maintaining a refined, architectural look that designers love.

Aquamarine is durable enough for everyday jewellery, but proper care will preserve its beauty:

• Clean gently with warm soapy water and a soft brush
• Avoid ultrasonic cleaners if the stone has inclusions
