Buddhist Engagement/Wedding Ring.
Multi-colored gold ring in the centre of a Platinum Diamond engagement ring.
Which incoporates details from a Tibetan Mandala.
The huge Mandala sand paintings always have  an outer border that represents the basic elements of the Universe (Air, Water, Earth and Ether). This was done with four different trapazoid-like gold sections (white, yellow, red and green). The Platinum engagement ring has a 1.25ct Brilliant cut Diamond along with some 18kt yellow gold filigree.
