Do Lab-Grown Diamonds Hold Their Value?
Quick Answer
Do lab-grown diamonds hold their value?
No — lab diamonds have not held value well. Prices declined 60–80% from 2020 to 2026 due to rapidly expanding supply. A $4,000 lab diamond from 2020 might sell used for $400–$700 today. If resale value is important, natural diamonds are a better choice (though they also depreciate when resold).
📊 1-carat lab diamond retail prices: $4,000 (2020) → $1,200–$1,800 (2026) — a ~65% decline in 6 years.

Why Have Lab Diamond Prices Fallen?
The price decline is driven by supply and demand economics:
- Massively expanded production: Hundreds of new CVD labs opened in China, India, and the US between 2019–2023
- Production cost declines: Efficiency improvements cut per-carat production costs by ~50% between 2018–2024
- Market saturation: Supply grew faster than consumer demand
- Consumer expectations: As consumers learned lab diamonds are cheaper, they stopped paying premium prices
Bottom Line: Should Value Matter to You?
For the vast majority of buyers, diamond resale value should not be a primary concern. Most people buying engagement rings will not sell their diamond — it's a symbol of commitment kept forever. The meaningful question is: what gives you better value for your money as jewelry?
Answered that way, lab diamonds win decisively — you get a larger, more beautiful diamond for the same budget. The fact that it won't appreciate in value is irrelevant if you never plan to sell it.
Our recommendation: Buy a lab diamond if it's for jewelry. Buy a natural diamond if resale value is a genuine priority.
