Are Juja Diamonds real diamonds?
Yes. Juja Diamonds supplies 100% genuine lab-grown diamonds that are optically, physically, and chemically identical to earth-mined diamonds. They are made entirely of pure carbon and exhibit the exact same hardness, brilliance, fire, and durability. The only difference is that they are grown in a high-tech laboratory environment rather than extracted from the earth.
How are your lab-grown diamonds certified?
Every diamond in our collection is independently tested and graded by accredited gemological laboratories, primarily the International Gemological Institute (IGI). Your diamond comes with an official digital and paper grading report detailing its exact 4Cs (Cut, Color, Clarity, Carat Weight) and physical dimensions. Additionally, each certified stone features a microscopic laser inscription on its girdle matching its official report number.
What growth methods do you use for your diamonds?
We source premium stones created using both High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD) growth processes. Every IGI grading report explicitly discloses the growth method used for that specific stone, ensuring complete technical transparency for both retail buyers and commercial clients.
Can I order custom lab-grown diamonds or custom jewelry settings?
Yes. We specialize in custom diamond solutions tailored to your exact specifications. Whether you need a specific fancy shape (such as an elongated oval, radiant, or emerald cut), custom millimeter dimensions, or a completely bespoke fine jewelry piece, our team works closely with you throughout the entire process from stone selection to final setting.
Do you offer wholesale sourcing and bulk parcels for B2B buyers?
Yes. Juja Diamonds serves jewelry retailers, manufacturers, wholesalers, and independent designers across global markets. We supply trade clients with certified loose stones, matched side-stone parcels, and reliable inventory supply built on strict batch consistency and uniform color and clarity grading.
What is the difference between an IGI certificate and an in-house store grading report?
An IGI certificate is an uncompromised, third-party scientific audit conducted by independent gemologists under ISO 17025 accredited standards. In-house jeweler reports are created by the seller, which creates a potential conflict of interest. Third-party IGI certification guarantees that your diamond's quality metrics are completely verified and unbiased.
How do I choose the right diamond within my budget?
To maximize value, we recommend prioritizing Cut grade first, as a well-cut stone reflects light best and maximizes sparkle. For clarity, selecting eye-clean grades such as VS1 or VS2 allows you to get an visually flawless appearance without paying extra for microscopic grades. You can easily filter through cut, clarity, and carat weights in our online catalog.
