FAQ About Wholesale 1 Carat Lab Grown Diamonds
What shapes appear the largest in 1-carat lab diamonds?
Oval, Pear, and Marquise cuts generally look larger than a 1ct Round Brilliant because they have an elongated shape and distribute more carat weight on the upper surface (table).
Do you offer 1-carat diamonds in parcel goods (bulk lot)?
Yes, we supply uncertified or certified 1-carat diamonds in tightly sorted parcels (by color and clarity) for volume buyers and jewelry factories.
Can I choose specific color and clarity combinations for my batch order?
Absolutely. You can specify parameters like "1ct, F-G color, VS1 clarity, Ideal cut" and we will pull matching lots from our inventory.
Which certification is more standard for 1ct lab diamonds, IGI or GIA?
IGI is currently the most widely accepted and volume-standard certificate in the lab-grown diamond market, but we also offer GIA-certified 1ct diamonds upon request.
Is there a minimum order quantity (MOQ) for wholesale 1ct loose diamonds?
For wholesale pricing on loose stones, our MOQ usually starts at 5-10 carats total weight, or a minimum dollar amount per invoice. Contact us for details.
Are your 1ct diamonds produced via CVD or HPHT technology?
We utilize both advanced CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) methods, optimizing the technology based on the specific shape and crystal purity required.
Do your 1-carat HPHT diamonds suffer from phosphorescence (blue nuance)?
No. Our factory utilizes a slow-growth tuning process that controls boron impurities, ensuring our 1ct diamonds have zero blue nuance and do not glow in the dark after UV exposure.
Can you provide matching 1ct diamond pairs for studs or earrings?
Yes, we can perfectly match pairs of 1-carat diamonds based on exact millimeter dimensions, cut symmetry, color, and clarity.
