In a landmark decision for major trade hubs, the Dubai Multi Commodities Centre (DMCC) has officially separated lab-grown diamonds into its own distinct sector, decoupling it from natural diamonds and colored gemstones. This strategic division reflects a growing belief that the true growth potential for lab-grown diamonds extends far beyond traditional jewelry, positioning the material as a crucial component for next-generation semiconductors and advanced industrial technology.

GIA will introduce a new grading system for lab-grown diamonds from Oct. 1. Learn how “premium” and “standard” classifications work, fees, and submission rules.
GIA has announced major changes to its grading system for lab-grown diamonds. The update takes effect on October 1.
Why the change?
According to GIA’s president and CEO, Pritesh Patel, most lab-grown diamonds fall into a narrow range of quality. Using the same terms as natural diamonds no longer makes sense.
From October, lab-grown diamonds in the D–Z color range will be classified as either premium or standard.
To be graded as premium, a lab-grown diamond must meet all of these:
Clarity: Very, very slightly included (VVS) or higher
Color: D
Polish: Excellent
Symmetry: Excellent
Cut (round brilliant only): Excellent
A lab-grown diamond will be classified as standard if it meets these:
Clarity: Very slightly included (VS)
Color: E to J
Polish: Very good
Symmetry: Very good (good allowed for fancy shapes)
Cut (round brilliant only): Very good
Diamonds that don’t meet at least the standard level will not receive a grading.
Assessment fee: $15 per carat (minimum $15)
Non-qualifying stones: $5 evaluation fee
Minimum weight: 0.15 carat
Inscription: Each stone will be laser-marked with “laboratory-grown” and a GIA quality number
Document: Printed evaluation results will be provided
If you deal in lab-grown diamonds, this change will directly affect your inventory.
Do your stones qualify as premium or standard?
Will customers see more value in a premium grade?
How will this impact pricing in your market?
The new GIA system could shift how buyers compare lab-grown diamonds with natural ones. As a seller, you may need to rethink how you present and price your stones.
GIA is changing how it grades lab-grown diamonds. Starting Oct. 1, stones will be classified as either premium or standard instead of using natural diamond terms. Premium requires the highest grades in clarity, color, cut, polish, and symmetry. Standard covers a wider range. Diamonds below standard will not be graded. Fees start at $15 per carat.

A must read for practising gemologists and lab gemologist. Many thanks to Gems & Gemology.
Without sophisticated analytical gem testing instruments it is virtually impossible to identify and interpret the diagnostic features of CVD- Grown diamond. Many thanks to Gems & Gemology and GIA researchers for sharing the report.
Many thanks to Martin Winter of Mirror U.K and QueenSmith U.K for sharing an interesting story and poll on the difficulty of differentiating natural diamonds from lab-grown diamonds by the consumers in the U.K. Do you think the rest of the world are that smart? Not really. Even experienced jewelers make mistakes like their consumers with natural diamonds and lab-grown diamonds. If doubtful always consult a reputed diamond testing laboratory like the GIA.
Greenlab is the largest cultivator of diamonds in the world. Recently Greenlab sold a round, 7.5 cart, F color, VVS2 clarity polished diamond to the Indian government so Prime Minister Narendra Modi of India could present it to Jill Biden at a state visit to the White House in the U.S.

Sign of the times. Edahn Golan's insightful report is a must read.
Edahn Golan's insightful report is a must read.
Victoria Gomelsky's report along with Ada Diamonds was spot on. What matters between natural diamonds and lab-grown diamonds are the interpretations by lab-grown diamond producers and diamond experts, but sadly most consumers won't be able to see the difference.
Nina Notman was spot on. Regardless of their, size and color, the process of growing diamonds is neither easy nor quick. This is why lab-grown diamonds are not cheap.
The Natural Diamond Council has debuted Assure 2.0, which rates testers on their ability to distinguish natural diamonds from lab-grown diamonds.
According to Edahn Golan, jewelry with lab-grown diamonds comprises around 10% of U.S. diamond engagement ring sales so far in 2022. The numbers were calculated by Tenoris, the consultancy Edahn Golan cofounded with Chris Casy, former National Jeweler publisher. Tenoris calculates its numbers using data from 1200 specialty jewelry stores in the U.S. Take note.
