Buying guide
The round brilliant is cut to return the most light of any shape, so it gives the most sparkle. A 4 carat round lab-grown diamond is roughly 10 mm across. As a solitaire, it sits alone on the band with nothing to distract from it, the most traditional engagement ring look there is. Prongs hold the round center up high so light enters from the sides as well as the top.
White gold is gold alloyed with white metals and plated with rhodium for a bright finish. The plating wears over time and can be renewed. 10K is the hardest, 14K balances durability and gold content and is the most common choice, and 18K has the most gold. All three give the cool white look that keeps a colorless center looking crisp.
