News : Red-Hot Rocks - July’s Birthstone

Ruby

There’s a saying that the ‘price of wisdom is above rubies’. That is certainly true, but hey, you can’t wear wisdom on your finger or around your neck. Ok – so wisdom is probably somewhat more useful than a ruby or two – but this saying just goes to show how highly prized these little red gems have been throughout history. Read More

Ruby : as a mineral

Ruby is a light pink to blood red gemstone, a variety of the mineral corundum (aluminium oxide). The common red color is caused mainly by the element chromium. Its name comes from ruber, Latin for red. Other varieties of gem-quality corundum are called sapphires. It is considered one of the four precious stones, together with the sapphire, the emerald and the diamond. Improvements used include color alteration, improving transparency by dissolving rutile inclusions, healing of fractures (cracks) or even completely filling them.

Prices of rubies are primarily determined by color (the brightest and best "red" called Pigeon Blood Red, command a huge premium over other rubies of similar quality). After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions will indicate the stone has been treated one way or another. Cut and carat (size) also determine the price.
