Gems of Solitaire
RUBY NOTES
Eye-flawless ruby, particularly unheated ruby, is extremely rare. However, small amounts of rutile inclusions can be beneficial to break up and scatter light throughout the gem.
Over ninety-five percent of rubies on the market are heat enhanced.
Ruby of similar Burmese appearance has been found in Pakistan, Vietnam,
Mozambique and elsewhere. The appropriate term would be ‘Burma-type’ to use when discussing ruby from these sources.
Like rubies from Thailand, gems from East African sources all contain traces of iron, which makes a ruby brownish and with very little fluorescent.

MORGANITE NOTES

COLOURS
Pink to orange-pink
ALEXANDRITE NOTES
With the exception of some varieties of fancy colour diamonds, alexandrite is the rarest gemstone.
Discovered in 1830 near the Tokovaya River, what makes this gem remarkable is its leap across the colour pallet (other colour change gems shift only to the adjacent hue).
To be considered a fine gem, the colour change must be distinct and dramatic. Given alexandrite’s rarity, well-cut stones are the exception rather than the rule.
Russian origin command a premium, while its main origin today includes Brazil, Tanzania, Madagascar and India.
COLOURS

The tsavorite’s crisp brilliance contrast an emerald’s satiny brilliance. Also, tsavorite, like all garnets, is singly refractive. However, its high refractive index and light dispersion ads life to the gem.
Tsavorite is not brittle, and tough enough to stand up well to daily wear.
Demand is typically for a visually pure green with about fifteen percent secondary blue hue.
Eye-visible inclusions would lower the cost significantly.
COLOURS
Medium to dark yellowish green, green, slight bluish green (7.5GY, 10GY, 2.5G)

a) 2,100-6,750 USD
TANZANITE NOTES
The difference between blue at seventy-five percent tone (preferred) versus blue at eighty-five percent tone is what separates the finest colour from second best.
The finest gems will show a blue primary hue with just a hint of purple secondary hue.
Tanzanite will shift colour when the viewing environment is switched from daylight to incandescent lighting.
COLOURS
Purple, violetish purple, violet, bluish violet, violetish blue, blue (2.5PB, 5PB,7.5PB, 10PB, 2.5P)

a) 300-900 USD
Fine Grading 1ct:
a) 750-1,425 USD
AQUAMARINE NOTES
Though Latin for “sea water” denoting a greenish blue hue, aquamarine is valued primarily for the purity of its blue hue. The darker the stone, the more it will be valued. However, darker-toned stones are almost always grayish.
Most of the finest aquamarine comes from Brazil.
Majority of aquamarine is heat-treated, and increases the value of this gem
COLOURS

a) 200-800 USD
