Lab Grown Alexandrite in Bangkok: Custom Cuts, Bespoke Shapes & Jewelry Made to Order

Alexandrite is the gemstone that refuses to sit still. Green in daylight, red under incandescent light: "emerald by day, ruby by night," as the old trade saying goes. It is also one of the rarest gemstones on earth in its natural form, which is exactly why lab grown alexandrite has become one of the most requested stones at our office in Bangkok's Jewelry Trade Center.

At Lab Grown Dreams, we manufacture and supply lab grown alexandrite with true, dramatic color change, and because we cut in house, we can shape it to whatever your design demands. If you are searching for where to buy lab grown alexandrite in Bangkok, Thailand, or anywhere in Southeast Asia, this guide covers everything you need to know, and how to get a stone cut specifically for you.

What Is Lab Grown Alexandrite?

Lab grown alexandrite is real alexandrite, chrysoberyl colored by chromium, grown in a controlled laboratory environment rather than mined from the earth. It has the same chemical composition (BeAl₂O₄), the same hardness of 8.5 on the Mohs scale, and the same signature color-change phenomenon as natural alexandrite. The only difference is origin.

That difference matters enormously for price. Fine natural alexandrite with strong color change routinely sells for $15,000–$70,000 per carat and is nearly impossible to source in clean qualities above 1 carat. Lab grown alexandrite delivers the same optical drama at a small fraction of the cost, in sizes and clarities that simply don't exist in the natural market.

Why the Color Change Is the Whole Point

Not all "alexandrite" sold online actually changes color. Much of what is marketed cheaply as alexandrite is actually color-change corundum (synthetic sapphire), which shifts from greyish-blue to purple, pretty, but not alexandrite.

True lab grown alexandrite shows the classic shift:

• Daylight / fluorescent light: bluish-green to teal green

• Incandescent / warm light: raspberry red to purplish-red

When you enquire with us, we photograph and video every stone under both lighting conditions before you commit, so you see exactly what you are buying. This is standard practice for every alexandrite that leaves our office.

Custom Shapes and Bespoke Cuts, Cut in Bangkok, For You

This is where working with a manufacturer instead of a reseller changes everything. Most online sellers offer alexandrite in a handful of calibrated sizes: 6x4 ovals, 7x5 cushions, round brilliants. If your design needs anything else, you're out of luck.

We cut in-house at the Jewelry Trade Center on Silom Road, drawing on more than 35 years of family heritage in the gem trade. That means we can produce:

• Classic cuts — rounds, ovals, cushions, emerald cuts, pears, marquise

• Precision and fancy cuts — hexagons, kites, shields, trillions, portrait cuts

• Calibrated sizes for production jewelry and replacement stones

• Matched pairs and suites for earrings and multi-stone designs

• Fully bespoke shapes cut to your CAD file, sketch, or even a hand-drawn outline

If you are a designer who needs a 9mm elongated hexagon with a specific depth to fit an existing setting, or a collector who wants a one-off freeform cut that maximizes the color change face-up — that is exactly the work we love. Send us the dimensions, and we cut to them.

Lab Grown Alexandrite Jewelry, Made to Order

We don't just sell loose stones. As a full custom jewelry house, we take your alexandrite from rough to finished piece under one roof:

Engagement rings: Alexandrite is a spectacular non-traditional center stone, and its 8.5 hardness makes it genuinely suitable for daily wear, unlike softer color-change stones.

Pendants and earrings: Where the stone moves between lighting environments all day, showing off the color change constantly.

Men's jewelry and statement pieces: Including bolder cuts and larger carat weights that would be unobtainable in natural alexandrite.

Heirloom-style bespoke commissions: designed with you from CAD render to casting, in gold or platinum, with IGI or GIA certified lab grown diamond accents if desired.

Because we manufacture in Bangkok: one of the world's great jewelry production hubs, you get workmanship that international brands charge five times more for.
