Questions About The Brownstone Collection
Are these natural or lab-grown diamonds?
Every diamond in The Brownstone Collection is a natural diamond — not lab-grown, not treated, not enhanced. The warm cognac and champagne tones are geological, formed over billions of years. This is our premium natural tier, priced above our lab-grown white diamond collection to reflect the rarity of these stones.
What is the difference between cognac and champagne diamonds?
Both are natural fancy color diamonds graded on the Argyle C1–C7 color scale. Champagne (C1–C4) is lighter and golden — warm, versatile, beautiful in rose gold. Cognac (C5–C7) is deeper and richer — bold amber-orange, striking in yellow gold or platinum. Read our complete guide for the full breakdown.
