Diamonds are Forever

Possessing the highest shine of all transparent gemstones, diamond is the hardest material on earth that can only be scratched with another diamond. Its name comes from the ancient Greek adámas meaning “unbreakable”.

Diamonds reflect light in an unparalleled way, especially when placed under directional spotlights. With every slight twist of the hand, a diamond ring will shimmer in endless ways demanding attention.

Understanding the 4 C’s

In order to determine their quality, diamonds are graded using the 4C's system: carat weight, color, clarity and cut.

Burning with Passion

A variety of the corundum family, ruby is famous for its deep red hue and vibrant glow. Bearing the color of love and desire, ruby is the ideal romantic gift for a woman in love.

Record breaker

Over the years, finest-quality rubies have broken auction price records, commanding the highest per-carat value of all colored gems.

Watch for the Silk

Pure rubies exhibit thin inclusions called needles. When they intersect in groups, they create a phenomenon called “silk” which softens the color causing the light to beautifully scatter across the stone’s facets.

The ruby’s bright red hue can be paired with any gold color: white, rose, yellow and gold, but also platinum.

Rich in Symbolism

Known for its intense green shade and a clear depth of colour that very few gems possess, emerald is the precious stone that symbolizes renewal and hope.

A Royal Affair

The rich green stone has been a gem of fascination for royalty in the past centuries. Cleopatra, the famous Queen of Egypt, had a soft spot for lush emeralds and loved wearing them.

The Perfect Cut

The precious stone often has intricate inclusions called “jardin” (the French term for garden) which make cutting the gemstone more challenging. Gem cutters have hence developed a special cut called emerald cut which gives the stone a rectangular or square shape.
