Frequently Asked Questions
Yes, The Federal Trade Commission (FTC) The FTC's 2018 Jewelry Guides rules around lab-grown diamonds, stating that a diamond is a diamond regardless of whether it is lab-grown or mined.
The major advantages are:
- Value — 70%+ less in price than a mined diamond
- Sustainability — GRWN diamonds are manufactured with solar and wind power Ethical
- Sourcing — GRWN diamonds are not manufactured in conflict free countries.
There are no disadvantages to buying a lab-grown diamonds.
Write a clear and concise answer to guide your customers.
No. There are many synthetics and imitations gems available in the marketplace including cubic zirconia and moissanite.
In the last five years, the lab grown engagement ring market share has exceed 50% of purchases.
Yes, they have the identical refractive index of a mined diamond. Brilliance is a result of precision cutting and polishing.
Sophisticated testing equipment is required to tell the difference between lab grown and mined.
This is a personal choice. Moissanite is a silicon carbide and a Diamond if formed from carbon.
A lab-grown engagement ring can purchased staring under a $1,000.00.
Only with testing equipment, not with the naked eye, loupe or a gemscope.
Consumers are quickly changing their buying preference for lab grown versus mined diamonds.
GRWN’s lab grown diamonds are manufactured by CVD (Carbon Vapor Displacement) and will not change color. There is an alternative process called HPHT (High Pressure- High Temperature) that may result in a milky or cloudy effect, also known as fluorescence.
GRWN’s lab grown diamonds are manufactured by CVD (Carbon Vapor Displacement) and will not change color. There is an alternative process called HPHT (High Pressure- High Temperature) that may result in discoloration over time.
GRWN’s lab grown diamonds are manufactured by CVD (Carbon Vapor Displacement) and will not change color. There is an alternative process called HPHT (High Pressure- High Temperature) that may result in fluorescence which will glow under fluorescent light sources.
No, lab-grown diamonds don’t lose sparkle.
No, all diamond's brilliance is subject to cutting and polishing perfection.
GRWN’s lab grown diamonds are manufactured by CVD (Carbon Vapor Displacement) and will not change color. There is an alternative process called HPHT (High Pressure- High Temperature) that may result in a milky or cloudy effect, also known as fluorescence, which may look blue or purple.
Color is a personal preference; however most client prefer a white diamond which lacks the presence of noticeable color.
D Color. The grading system is the same for all diamonds.
Yes. They can be gemologically tested with an instrument: Thermoelectric or thermoelectrical conductivity. This tester measures the rate of heat transference through a stone. Diamonds have high thermal conductivity, so the tester sends a small amount of heat through the stone and measures how fast the heat is dispersed. A rapid dissipation of heat indicates that the material is likely a diamond.
Yes, 1 out of 3 diamond engagement rings are purchased with lab-grown diamonds.
Yes, there are a few names / abbreviations - LGD, Lab Grown, Lab Diamonds.
