From the Workshop
Jewelry advice shouldn't come from a content factory.
PrimeStyle is the manufacturer. We have made diamond jewelry in our own US factory since 2001, and we answer customers' questions ourselves. These guides say the same things we say at the bench: where quality matters, where it doesn't, and where your money is best spent.
Need the Basics?
Learn Diamonds from the Beginning
The "3 C's" of diamonds are actually four: cut, color, clarity and carat weight. Start there, then cover shapes, metals, settings, sizing, and how lab-grown compares to natural.
Still Not Sure?
Ask someone who works with diamonds every day.
Tell us what you're considering, your budget and what matters most. We'll help you narrow it down.
Or contact us and a jeweler will answer.
