Rubies at Margems
Ruby is the red variety of corundum and one of the most valuable coloured stones. At Margems you can buy faceted rubies ready for setting and rough for cutting to your own project.
The most desirable shade is the rich red 'pigeon blood'. The main sources are Myanmar (Burma), Mozambique and Thailand. Most rubies on the market are heat-treated - we always state this on the certificate. For stones of significant weight we provide a lab report (GRS, GIA, SSEF or equivalent) with colour, weight, origin and treatment type.
You describe the brief - shade, weight, budget, purpose - and a manager selects specific stones with photos and certificates. Prices are in USD; payment and shipping are agreed individually.
