LAB GROWN GEMSTONES COLOR CHART
Color Grading Scale for Lab-Grown Diamonds (GIA D–Z standard; the same grading system used for natural diamonds)
For colorless lab-grown diamonds (produced via CVD or HPHT methods), the **GIA D–Z** color grading scale is used. "D" is the highest grade, with yellow tones becoming increasingly apparent further along the scale; diamonds graded beyond "Z" are classified as "fancy color" diamonds, for which the D–Z scale does not apply.
Lab Grown Diamond Color Chart (IGI & GIA)
White lab diamonds use the GIA D–Z scale. D = highest colorless grade; tint (yellow/brown/grey) increases from D to Z. Fancy colors do NOT use D–Z.
- Colorless (D, E, F) D: Absolute colorless, icy white. E: Colorless, faint tint invisible naked eye. F: Colorless, slight tint only visible vs D/E.
- Near Colorless (G, H, I, J) | Best sellers G: Face-up white, subtle warmth only beside DEF. H: Clean white face-up, faint warmth on side view. I: Mild yellow tint noticeable on loose/large stones. J: Clear warm undertone.
- Faint (K, L, M) Visible light yellow, ideal for yellow gold settings.
- Very Light (N–R) Distinct yellow, mainly for accent stones.
- Light (S–Z) Strong yellow/brown, not sold as white diamonds.

Which gemstones can be grown in a lab?
Diamond, fancy colored diamond, sapphire, ruby, spinel, emerald, alexandrite, moissanite, and opal. Every year, technology advances and more opportunities are available. Even in just the last five years, There’re huge advancements in the methods used to grow colored gemstones.
As you can see the pictures from this page, these colors are lab grown, and more and more colors will be created for the jewelry designs.
How these Lab grown gemstones are made?
Most of them are created with the methods by Pulled Czochralski , The Czochralski process, uses radio waves to melt the aluminum oxide. A rod tipped with a seed crystal is inserted into the mixture and slowly rotated and pulled out, creating a column of Colored stones.
Take the Blue Sapphire Gemstone for an example to explain this process:
What's Pulled Czochralski Blue Sapphire Gemstone?
Flame fusion creates long, tear-shaped pieces ofsynthetic corundum. Consisting of a mix of aluminum oxide and chromium, would have yielded asynthetic ruby.
Another melt process, the Czochralski process, uses radio waves to melt the aluminum oxide. A rod tipped with a seed crystal is inserted into the mixture and slowly rotated and pulled out, creating a column of sapphire.
The lab created Blue Sapphire can also be created by flame fusion but the quality and resemblance of synthetic Blue Sapphire created by Czochralski Pulled processis considered to be the best and superior to all other lab created Blue Sapphire.
As It follows the same process as natural Blue Sapphire is created make it the most superior among other Blue Sapphire. Natural Blue Sapphire are rare and over-valued. It is better to buy synthetic Blue Sapphire made by Pulled method as they have exact same chemical composition and physical composition and are sold at fraction of price of natural Blue Sapphire. They also appear brighter and more vivid than natural Blue Sapphire making it the better than corundum blue sapphire stones.
