GemGuide Updates Ruby Prices
Its app now reflects increased prices for Mozambique ruby, as well as changes to its Burma ruby charts.

“For at least the past decade, Mozambique has been the main source for gem-quality and near-gem-quality ruby entering the global market, not Burma. Burma is the iconic locality that sets the value benchmark for gem ruby. Mozambican ruby is the product that the market can get,” said Research Director Stuart Robertson in an email to National Jeweler.
“The current appetite for ruby, especially unenhanced material, has been very good, and is largely sold via a tender system. As a result, prices in the Mozambican category have also skyrocketed.”
The company has also made changes to its Burmese ruby charts.
Due to scarcity of material in the unenhanced Burma ruby category, price is secondary to availability, GemGuide said.
Sourcing fine material is now “very difficult,” the company added, making prices offered in accordance with its traditional 1-to-10 quality range “no longer practical.”
“We have been watching this [scarcity] develop for several years. The lack of availability has now gotten to the point that I felt it was necessary to alter our approach to pricing Burma,” said Robertson.
Beginning with its forthcoming July/August 2026 issue, the Corundum-Ruby (attributed to Burma, unenhanced) chart will provide pricing for four grades.
They are 3 (Middle Commercial), 5 (Lower Good), 8 (Upper Fine), and 10 (Upper Extra Fine).
To price other grades, GemGuide users should interpolate from the listed categories, it said.
The changes to ruby pricing are live now in the app and will be reflected in the July/August 2026 issue.
GemGuide also noted that changes to sapphire prices will be released along with the launch of the issue.
Access to pricing tables is for subscribers only.
GemGuide welcomes feedback on these new updates as market research continues.
Thoughts and suggestions on pricing can be directed to Robertson at srobertson@gemguide.com or Editor-in-Chief Brecken Branstrator at bbranstrator@gemguide.com.
