Frequently Asked
What\'s the most important of the 4 C\'s?
Cut. A poorly cut diamond at high color and clarity grades will look duller than a well-cut diamond two grades down. We tell most customers: prioritize Excellent or Ideal cut, then optimize color and clarity within budget. Carat is the lever you choose last.
Are lab-grown diamonds real diamonds?
Yes — chemically, optically, and physically identical to mined diamonds. Same crystal structure (cubic carbon), same hardness (10 on the Mohs scale), same refractive index. A gemologist with a loupe can\'t distinguish them; only a $25,000 spectroscopic machine can. The only practical difference is origin (lab vs. mine) and price (lab is roughly 40–70% less per carat).
What carat weight looks right on the finger?
Median US engagement ring is 1.0–1.5 ct. On a size 5–6 finger, a 1.0 ct round reads as "tasteful." On a size 7+ finger, the same ring can look smaller than expected. Elongated shapes (oval, pear, marquise, emerald) face up larger per carat than rounds — sometimes by 15–20%.
What color grade is "white enough"?
D–F are colorless and price aggressively. G–H are near-colorless and most people can\'t see the difference unaided — this is where we usually point the budget. I–J start to show a faint warmth in larger stones; on yellow gold this can disappear, on white gold or platinum it\'s more visible.
What clarity grade is "clean enough"?
VS1–VS2 means inclusions exist but you can\'t see them without 10x magnification. SI1 is the sweet spot for most budgets — often eye-clean depending on inclusion location, but priced 20–30% below VS2. We hand-pick SI1s for eye-cleanliness; not all SI1s are equal.
Should I trust a GIA report over an IGI report?
GIA is the older, stricter benchmark for natural diamonds. IGI is dominant for lab-grown and consistent on grading. Both are reputable. Avoid EGL (looser grading standards) and any "in-house" certificate from the seller as primary documentation.
How long should an engagement ring take to make?
Stocked rings ship in 24–48 hours. Made-to-order from our standard catalog: 7–10 business days. A loose lab diamond sourced through Nivoda: add 3–5 business days. Custom design (new CAD): 3–4 weeks. An in-house specialty cut (Portuguese, Dutch Marquise, etc.) adds another 1–2 weeks.
What\'s the biggest mistake first-time buyers make?
Overspending on a high color/clarity combination without checking the cut. A G/VS2 Excellent will out-sparkle a D/IF Good, every time. The other common mistake is sizing — borrow a ring she wears on the right finger, ship it to us, we\'ll measure it free.
