Our core motivation to present our short gem courses is to emphasise the rarity and beauty of diamonds and coloured stones. As a further extension of this initiative, due to demand we plan to offer rare, unaltered coloured stones to discriminating gem connoisseurs.
Our first offers will be demantoid garnets from Russia and rubies from Mogok, Burma. All gems were acquired years ago and I have tested them to confirm they have not been altered. During our marketing set-up a problem arose when I attempted to photograph my demantoids for website illustrations. Rendering faithfully the hues of green gems rich in chromium (emerald, alexandrite and demantoids) in a photograph are notoriously difficult: my eyes saw an attractive vivid green of medium tone but my camera produced an ugly grey-green of poor saturation and tone. My photographic efforts do not do justice to the beauty of my gems. So how best to illustrate my demantoid garnets?
