"There’s a tremendous amount of craftsmanship between having a great idea and having a great product."
High Pressure High Temperature (HPHT) growth uses controlled pressure and heat so that carbon crystallises onto a diamond seed.
Chemical Vapor Deposition (CVD) is a cutting-edge technique for growing high-quality diamonds by introducing carbon-containing gasses into a vacuum chamber, where carbon atoms form diamond crystals on a substrate, allowing precise control and potential applications in electronics and cutting tools.
Use the current Lumex catalogue to review the growth method listed for an individual diamond. Availability of HPHT- and CVD-grown diamonds can vary.
Cutting and polishing influence a diamond's proportions, symmetry and light performance. Review the specifications, origin information and grading report shown for each available diamond.
Review the current catalogue for available fancy shapes and compare each diamond's measurements, proportions and light-performance information.
Fancy-colour availability varies by hue, intensity, size and grading information. Contact Lumex about requirements that are not shown in the current catalogue.
When a grading report is listed, use the issuing laboratory's cut, polish and symmetry grades for that diamond rather than assuming those grades across the catalogue.
The current catalogue may include specialty cuts alongside traditional shapes. Review each available diamond's measurements and specifications when planning a jewellery design.
