Step 1 — Start With Shape
Shape is the diamond’s silhouette and the biggest driver of “look” and style.
Most-loved shapes
Round: maximum sparkle, timeless
Oval: elegant lengthening effect, bright brilliance
Emerald: clean lines, “hall of mirrors” sophistication
Princess: modern, sharp sparkle with a structured look
Marquise: elongated and bold, creates a larger visual presence
Pristine tip: If you want the most sparkle, start with Round. If you want a larger look for the carat, explore Oval or Marquise. If you love quiet luxury, Emerald is iconic.
Step 2 — The 4Cs (What Matters Most)
Diamonds are graded by Carat, Cut, Color, and Clarity. Here’s what to prioritize.
Carat (Size)
Carat is the diamond’s weight and a strong indicator of size.
Pristine tip: Shape affects size appearance—some shapes look larger at the same carat weight.
Cut (Sparkle & Light Performance)
Cut controls how well a diamond reflects light—this is where brilliance and fire are born.
Cut grades you may see: Ideal / Excellent / Very Good / Good
Pristine tip: For maximum sparkle, aim for Excellent/Ideal where available.
Color (How White the Diamond Looks)
Cut controls how well a diamond reflects light—this is where brilliance and fire are born.
Cut grades you may see: Ideal / Excellent / Very Good / Good
Pristine tip: For maximum sparkle, aim for Excellent/Ideal where available.
Color (How White the Diamond Looks)
Color is graded from D (colorless) downward.
Pristine tip: Many diamonds in the near-colorless range look beautifully white once set, especially in yellow or rose gold
Clarity (Natural Inclusions)
Clarity measures internal characteristics (inclusions) and surface marks.
Common clarity grades: IF, VVS, VS, SI
Pristine tip: “Eye-clean” matters most—choose a clarity that looks clean to the eye, not only on paper.
Natural vs Lab-Grown Diamonds
Both are real diamonds. The difference is origin.
Natural Diamonds
Formed in nature over time. Many clients choose natural for rarity and tradition.
Lab-Grown Diamonds
Grown using advanced technology. Many clients choose lab-grown for value and size flexibility.
Pristine standard: Every diamond is clearly labeled as Natural or Lab-Grown.
Certification & Why It Matters
Certification is a professional grading report that confirms key characteristics.
You may see labs such as:
GIA
IGI
(and other recognized documentation where applicable)
Pristine tip: If certification is important for your purchase, check the product page details or contact concierge before ordering.
Matching Your Diamond to Your Setting
A beautiful ring is about harmony.
