Stone Guide
Burma Ruby
Origin: Mogok Valley, Myanmar
What Makes It Special
I've handled these stones for 30 years, and a true Burma ruby stands entirely alone. Look at the Sunrise Ruby—.3M for a 25.59ct stone. What you are paying for is the Mogok fluorescence; under long-wave UV, a true Burma ruby glows a fierce, undeniable red. Modern stones are almost all heated, which is why my favorite buys are Victorian and Edwardian estate pieces that predate commercial heat treatments. To me, if it doesn't have an SSEF or Gübelin report confirming no heat, it's just another red stone.
Required Documentation
No-heat Burma ruby commands the highest premium. Heated Burma ruby is still valuable but trades at 50-70% less than equivalent no-heat. Always confirm treatment status in the report.
Price Guide 2026
⚠️ No-heat commands full price. Heated Burma ruby: subtract 50-70%. Heated non-Burma: subtract another 50-70%.

Dealer's Notes
I anchor my pricing to reality. The Sunrise Ruby commanded .3M (.18M/ct) — that is your ultimate reference point for pigeon blood, no-heat Burma at the absolute top end.
I walk away when a claimed Burma ruby feels dead under a blacklight. Always do the UV fluorescence test. Hold it under long-wave UV; a genuine Mogok ruby glows strongly red. Weak or absent fluorescence equals highly suspicious.
The mistake most collectors make is ignoring the math of weight thresholds. A 2.01ct stone commands dramatically more than a 1.99ct stone. The market has strict size premiums, and I price precisely to those thresholds.
I buy Victorian and Edwardian estate jewelry because that's where the sleeper deals hide. Heat treatment wasn't commercially viable then, meaning rubies from that era are almost always unheated by default.
Burma rubies at serious price points should carry SSEF or Gübelin origin and treatment reports — this is standard practice in the colored stone trade, not an unusual demand. Purchasing subject to certification is a normal, professional approach. GIA is appropriate for less expensive stones or as a secondary cert. A dealer who refuses to allow subject-to certification on a significant ruby is worth questioning.
Frequently Asked Questions
What is pigeon blood ruby?
It's the baseline for perfection. The Sunrise Ruby at .18M/ct set the standard. It means vivid red, strong saturation, and specifically, that unmistakable Mogok fluorescence. If it doesn't glow red under UV, it's not pigeon blood to me.
How do I verify a Burma ruby is unheated?
You demand an SSEF or Gübelin report. Period. I don't care what the seller promises, and GIA alone isn't enough to catch the clever heat treatments we see today. The premium depends entirely on those two specific labs.
Why are Burma rubies so much more expensive than other rubies?
Because a genuine, unheated Mogok ruby that glows under UV is virtually impossible to replace. Combine that rarity with specific weight thresholds—where a 2.01ct stone is worth significantly more than a 1.99ct—and you realize you're paying for geological perfection.
Is Burma the same as Myanmar?
Yes, geopolitically, but in my business, 'Burma ruby' means Mogok Valley. I use the old name because that's what the market respects. The origin dictates the premium.
