Distinctive character

The elongated 9.8 mm outline and two intentionally faceted broad faces allow the stone to be viewed from either side. As the diamond moves, its dark brown body color can show warm golden-brown and subtle orange-brown reflections.

Clarity and setting guidance

Natural inclusions are clearly visible and form part of this exact diamond's individual character. They can affect transparency and brilliance. The pointed ends, shallow profile and heavily included structure call for careful handling. A qualified jeweler should inspect the stone before selecting a protective setting or finalizing a custom design.
