Our Sales process.
We carefully sort and grade coloured gemstones before selling them at private auction.
Sorting & Grading.
R&G sorting and grading of rough gemstones is a highly skilled process. Rough gems are sorted according to their colour, size, shape and clarity. Consistency is key to buyer confidence.
The Auction Process.
R&G ground-breaking auction process transformed the international supply of rubies and emeralds when it was introduced in 2009, bringing transparency and consistency to a previously chaotic practice.
