Top 10 Diamond-Alternative Gemstones For Engagement RingsThe most important requirement for an Engagement Ring is the durability of the gem. Engagement rings are supposed to be worn all the time and gems softer than 7-8 /10 on Mohs scale of hardness are not recommended though might be beautiful. Emerald is hard but it isn't recommended either because it cracks and chips easy.
Diamond is the classic gem for an engagement ring but it can be very expensive and many people can't afford it. On this list you can find different alternatives and some really affordable price ranges.
The Top Ten
Zircon is a natural gem and not synthetic despite its name it similar to Cubic Zirconia which is synthetic.
Zircon shares similar hardness with Aquamarine, Morganite, Emerald, to name a few. - Metal_Treasure
Morganite has emerald's hardness but unlike the emerald, it doesn't crack and chip very easy - Metal_Treasure
It's a synthetic gem made in labs to resemble diamond (synthetic gems are not fake gems). Its hardness is 8/10 - the hardness of topaz. It's a synthetic gem and not glass.
Most often you will see it marketed as "because".
On Amazon you can find rings at $30-40 in a sterling silver mounting. Avon also sell affordable Cubic Zirconia jewelry - the cheapest ones are perhaps between $50-80.
I think Cubic Zirconia is the most affordable thing and it looks very good, and it's pretty durable. - Metal_Treasure
It looks like diamond, it's almost as hard as diamond, but it's affordable. Its quality is better than that of Cubic Zirconia. - Metal_Treasure
A good diamond alternative but it can be more expensive than some other gems on this list. You know, sapphire is a valued gem but it's still less expensive than diamond. - Metal_Treasure
You have color choices and topaz is very hard - 8/10 - Metal_Treasure
You can opt for it if you want colored sapphire and don't insist on colorless one to resemble colorless diamond - Metal_Treasure
In the image you see a green crystal but you have many other color choices - Metal_Treasure
A very hard and durable gem but it can be too expensive (esp. high quality pieces) - Metal_Treasure
