14k white gold is one of the most popular choices for everyday engagement rings because it balances durability and beauty well. At 58.3% gold content, it has enough alloy hardness to resist everyday wear while still offering the bright, cool look white gold is known for. It is also more affordable than 18k or platinum. At this size, 3 carats puts you in a category most people only dream about. It delivers drama and luxury without crossing the line into impractical.

Do Amore offers free maintenance services on white gold. A 3 carat stone is well above average and a great choice for someone who wants their ring to look expensive and elevated without crossing into the ostentatious territory you hit at 4-5 carats. The price difference at this size is extraordinary, which is one of the most compelling reasons couples choose lab diamonds for larger center stones.
