How do I compare two lab-grown diamonds?
Start with certificate details, measurements, cut information, and videos of the actual stones. Then compare the price only after you know the stones are meaningfully similar.
Compare Lab Grown Diamonds Before You Buy.
Found a diamond somewhere else? Send it to IDAN before you buy. We will help you compare the certificate, dimensions, light performance, and price context, then search our supplier network for options worth considering.
Do not compare a line item. Compare the stone.
Two diamonds can share similar grading language and still present differently. IDAN’s focused brief is built around Round, Oval, Emerald, Pear, Marquise, Princess, Radiant, and Cushion shapes from 0.5 to 6+ carats, with D/E/F color, VS1/VVS2/VVS1 clarity, and Ideal or Excellent cuts only.
These are among the most premium combinations buyers seek today. Traditional jewelry markups can make a lower-quality color or clarity look expensive; IDAN compares the actual certificate, proportions, and price so your budget can reach a better-matched stone with personalized support rather than a big-box handoff.
Use this page as your pre-purchase checklist. Then send IDAN the actual diamond you are considering for a clear second look. Savings vary by stone and quote, so we make the comparison against real details, not an unverified blanket promise.
Five places to look before a price.
IDAN narrows the search to the details that matter: premium shapes, 0.5–6+ carats, D/E/F color, VS1/VVS2/VVS1 clarity, and Ideal or Excellent cuts.
01
Certificate
Confirm the laboratory, report number, and that the report belongs to the exact stone.
02
Cut & light
Look beyond the top-line grade. Proportions, facet pattern, leakage, and video affect how a diamond presents.
03
Measurements
Use millimeter dimensions and length-to-width ratio to judge visual size and shape, not carat weight alone.
04
Color & clarity
IDAN focuses on D, E, and F color with VS1, VVS2, and VVS1 clarity: premium grades selected for buyers who want a cleaner, brighter standard.
05
Price context
Compare the full specification, return terms, setting plans, and service, not a headline price in isolation.

These are the questions our advisors hear most often when somebody is close to buying.
Does a higher grade always mean a better-looking diamond?
No. A grading line cannot fully describe light performance, face-up size, or shape character. Two stones with similar reports may still look different in person or on video.
Is E color a better value than D?
That depends on the stone, shape, and buyer’s preference. The useful question is whether the visible difference is worth the premium for your specific options.
When is VVS1 unnecessary?
If a lower clarity option is visually clean in the exact stone and you prefer to direct more budget toward size, cut, or a setting, the additional clarity may not deliver a visible benefit.
What should I compare besides price?
Ask for the original certificate, actual stone video, dimensions, cut information, return terms, delivery expectations, and guidance about the finished ring if relevant. IDAN carries Ideal and Excellent cuts only.
