2026 Lab Grown Diamond Price Trends
As technology matures, lab grown diamond prices in 2026 have become very affordable. Market acceptance in Hong Kong has risen sharply, and after years of price adjustments, pricing is now more stable than ever.
IGI certified lab grown diamonds dominate today's market. Since GIA stopped providing detailed 4C grading in Q3 2025, simplifying to "premium" or "standard" classifications, IGI certificates now account for the vast majority of the 1ct+ lab grown diamond market.
Below is our latest lab grown diamond price table as of February 2026:
| IGI D IF (Flawless) | IGI D VVS2 (Premium Choice) | IGI E F VS (Elegant Entry) | |
| 1.0ct | 3,400 | 2,600 | 2,300 |
| 1.5ct | 7,100 | 4,400 | 3,800 |
| 2.0ct | 11,700 | 5,700 | 4,600 |
| 3.0ct | 19,000 | 9,400 | 6,500 |
Buying Recommendations
Choosing a lab grown diamond isn't just about finding the lowest price—it's about balancing quality certification with value based on your intended use.
Engagement Purposes: For this meaningful commitment, we recommend IGI D IF - VVS2 grades to truly reflect the preciousness of this gift.
Everyday Jewelry: For daily wear such as stud earrings or necklaces, IGI D VVS2 or E F grades are excellent choices. For multi-stone pieces like tennis bracelets, uncertified lab grown diamonds offer exceptional value—the visual difference is minimal to the naked eye, but you save significantly on certification premiums.
Beware of ultra-low prices advertised for 1ct lab grown diamonds—these often use uncertified stones. Without international certification, there's no guarantee of quality. At Diamond Culture, uncertified 1ct lab grown diamonds are priced around HKD 1,000+.
While uncertified diamonds can be considered when you have access to professional testing equipment in-store, we recommend them only for multi-stone jewelry like tennis bracelets where value is maximized. For engagement rings or solitaire pieces, we strongly recommend IGI certified diamonds when the price difference is reasonable.
