The brilliance boost is twofold. Firstly, the small diamonds in the halo create a continuous frame of light around the main diamond, blending its edges into the setting and making the center stone look significantly larger.
Secondly, the dense concentration of diamonds increases the overall reflective surface area, delivering overwhelming extra brilliance and sparkle that a solitaire simply cannot match. This makes the halo engagement ring a great choice for maximizing the impact of your chosen carat weight.
