Round cut diamonds, normally also called the brilliant-cut diamonds, are admired and loved for their classic shape and massive sparkle. They may be small, but they give off elegance and glow like no other. 

Typically cut with 58 facets, sometimes 57, if there is no culet, this round diamond was made to be as sparkly as possible. And because people usually covet diamonds for their sparkle, particularly women who treat diamonds as their shiny best friends, round cut diamonds are the most popular of them all. 

Because round cut diamonds are the most sparkly, and the shape is the classiest one, they are also easily the most expensive.

One tip that you can follow when you want to save a little is to be conservative about the carats you prefer. If you want a 1 carat round cut diamond because of the sparkle it will certainly give you, try scaling down to .90 to .95 carat diamond instead because they can still certainly sparkle a lot. They will still look as if they are of 1 carat, but cost less.

Silver not your partner's thing? How about rose gold? There are two great options from De Beers that you can check out. I'll give the other one on #10. 

This particular round cut diamond ring is part of the company and therefore says a lot of what it means when you give it to your partner. It features an interlocking thread pave and 18K rose gold color, which is really nice. The two interweaving bands certainly signifies your romantic journey.  

Given how the sparkly 1 CTW diamond is set against the romantic and feminue hue of 18K rose gold band, the additional surrounding pavé round brilliant diamonds certainly up the ante with this one. 

10. Infinity Rose Gold Solitaire Ring, De Beers, $8050

Another offering from De Beers to cap off this list is a ring of rose gold hue again. If #9 looks too plain for you, then this might be the trick. The ring features the unending symbol of infinity lined with pave diamonds.

If you think your partner is a piece of sparkly diamond, then this ring sends off a cool message. The round cut diamond is set against a white diamond pave set in an 18k rose gold band, as if showing just how precious you think your partner is.
