Top non-diamond engagement Rings

Diamonds did not always top the list for most desired engagement stone. When De Beers ran large-scale and effective marketing campaigns it changed the perception of diamonds and built a story around their aura. De Beers created a story of love, romance, and indestructible commitment around the diamond.

Controlling supply and directing demand, De Beers was able to build and control a market unlike other companies ever have.
Morganite is one of the hottest engagement ring alternatives. Morganite is traditionally pink to orange-pink in color and is often found in large sizes.

Garnet is a series of many different minerals each with its own unique chemical formula. Garnet comes in many colors. Reds and pinks seem the most popular for engagement rings.
Moissanite is a naturally occurring silicon carbide with similar look and characteristics of a diamond at a fraction of the cost.Tanzanite is 1000 times rarer than diamonds and is a single source gemstone ... and that source is running out. Tanzanite is a blue variety of zoisite with a rich deep blue and sometimes purple hues.
Oregon Sunstone is becoming more popular in an engagement ring. The inclusion of copper crystals within the Sunstone (plagioclase feldspar) is unique and imparts a speckled glimmer within the gemstone.

Tsavorite is a variety of garnet that hosts calcium-aluminum, and trace amounts of chromium and vanadium to impart the rich green color.
