Where Do I Start?

Buying diamonds can be an intimidating process. If you’re unsure of what to do next, we have a few questions you can ask yourself to get started.

  • Where do you want to spend your “diamond dollars"? In other words, which of the 4Cs is most important to you?
  • What shape fits her style? Whether you’ve already picked out a setting or are building your engagement ring by choosing your diamond first, picking a shape can help narrow down your choices.
  • Would you like a natural or lab-grown diamond? It’s a personal choice, and there are benefits to buying both types of diamonds.

What Is Diamond Subjectivity?

Every diamond grade is based partially on the subjective opinion of the grader. This means that you can actually end up with diamonds that have the exact same grade, but still look considerably different. At Shane Co., we only pick the prettiest diamonds from within each grade, ensuring that the quality of each diamond is at the highest possible level. You can even look at our diamonds with 360-degree videos, so you know that every angle is as beautiful as the last.

Budget Tips

Here are a few tips to get the most bang for your buck:

  • Go with a yellow gold setting for a yellow-tinted diamond — it will make the gemstone appear whiter!
  • An oval or marquise shape can create the illusion of a larger diamond
  • White sapphires are a great substitute for diamonds, at a much smaller price tag
  • If you choose a lab-grown diamond, you can get a larger diamond for your budget
  • “Off sizes,” such as .9- or 1.9-carat natural diamonds, typically cost less than full 1- or 2-carat diamonds
