Rarest Gems for Your Connoisseur Collector

These gems have life in them: their colors speak,

say what words fail of.

~ George Eliot

Color, Cut, Brightness…and Rarity

Rarity of the stones in any piece of jewelry contributes to its importance and value. In addition to the highly desirable classic ruby, sapphire, emerald and diamonds, there are several magnificent, rare and phenomenal stones that are must haves for any jewelry collection.


Rubies and Emeralds and Sapphires…OH My!!

Phenomenal and Rare Stones…A Must!

Oscar Heyman works with phenomenal stones such as Star Sapphires and Rubies, Chrysoberyl Cat’s-Eye, Alexandrites, Opals and rare stones such as red and blue Spinel, Tsavorite and Paraiba. Jewelry featuring such coveted stones are highly sought after by collectors and connoisseurs around the world.

Chrysoberyl Cat’s-Eye

As with many colored gems, stones with the most intense, rich colors are the highest valued. Honey-colored or variations of honey-colored Chrysoberyl Cat’s-Eye are considered the most valuable and the infamous milk-and-honey effect is the most desired.

Star Sapphire

The optical phenomenon responsible for star sapphire’s shimmering rays is called asterism, from the Latin word astrum, for “star.”  Asterism is caused by small needle-like inclusions of the mineral rutile.


This stone is known for its fascinating color change.  It can be found in a range of colors from green to red – colors you find in just one stone.


Any piece of jewelry showcasing this bright red stone, sometimes a rare blue one will come along — is an exquisite piece to be treasured.
