A single round brilliant cut lab grown alexandrite sits on top of this beautifully designed solitaire ring. Precision cut into a round shape, the stone is almost internally flawless and boasts terrific colour changing qualities. Take a look at alexandrite in natural light and you'll see intense flashes of emerald green mixed with hints of blue.
