Short answer: At $15,000 the key decision is mined or lab grown. With a mined diamond, this budget buys a high-quality natural center stone. With a lab grown diamond, you will likely spend far less than $15,000 even on a large, top-quality stone in 18K gold, and can put the rest toward wedding bands or other jewelry. Either way, insist on an independent grading report and an excellent cut.

How to Spend a High-End Budget
Put cut first: an ideal or excellent cut makes the biggest visible difference in sparkle. Then choose near-colorless color and an eye-clean clarity. Pick 18K gold for a rich finish, and make sure prongs are sturdy enough for a larger stone. Consider a matching bridal set so the engagement ring and wedding band fit together perfectly.
