Exquisite Gems

Every gem mounted in a piece by ESG Jewels is hand selected by Emmanuel Guillaume.
He travels the world over in search of those exclusive gems that can meet his high standards for quality and which he deems as "collectible" (a rare combination of colour, purity, brilliance, shape, and very important: the cut).
Only natural and untreated gems are chosen, which meet these stringent requirements.

These include rare, unheated Burmese rubies, outstanding Kashmir sapphires, "old-mine" Colombian or Indian emeralds and fancy colour diamonds and colourless diamonds. Other exclusive gems are also incorporated in the stunning jewels of ESG, such as fine spinels, imperial topaz and vibrant demantoid garnets.
Whether the stones are intended to be the centre piece of the item or a small accent, their quality must be special.
