0.40ct Diamond Solitaire Ring ~ Platinum


Showcasing an exquisite round brilliant cut diamond, this engagement ring is a contemporary classic. The simple bezel setting of the stone gives this ring an elegantly minimal and modern feel.

The hand selected diamond comes with a independent report from the Gemological Institute of America. This diamond has been graded as a Triple Excellent diamond by the GIA. Excellent cut, excellent polish, excellent symmetry. 

Round brilliant cut diamonds are special for several reasons. Well cut round diamonds boast mathematical precision in their faceting (the individual polished surfaces). This perfection creates optimal light return and intense sparkle.

When grading round diamonds, The Gemological Institute of America takes into account three factors of each stone: brightness, fire, and scintillation. A diamond's brightness refers to the white flashes you see when looking at the stone. Fire describes the rainbow flashes. Scintillation references the pattern created by brightness and fire. Diamonds are the most beautiful when you have ample brightness and fire coupled with balanced scintillation. 

Both the bezel setting and the band of this ring are crafted in platinum. Our jewellers love platinum due the strength, durability and bright white tone of this precious metal.

Designed and made with responsibly sourced materials in the Sargisons workshop in Hobart, Tasmania.
