Frequently Asked Questions
How much should you spend on an engagement ring?
Forget the outdated '2-3 months salary' rule — that was a marketing campaign by De Beers. Spend what you're comfortable with. The average in the US is about $5,000, but many couples spend $1,000-$3,000 and are thrilled with beautiful rings.
Are lab-grown diamonds real diamonds?
Yes — they are chemically, physically, and optically identical to mined diamonds. Even jewelers can't tell them apart without specialized equipment. They're graded on the same 4C scale. The only difference is origin (lab vs earth) and price (30-50% less).
Why does engagement ring cost different in St. Louis than other cities?
St. Louis's costs reflect local labor rates driven by the diversified economy, varied climate conditions that affect materials and scheduling, and moderate permitting requirements. The balanced labor market also influences competitive pricing.
