Yes. Lab-grown diamonds are optically, chemically, physically, and thermally identical to mined diamonds, though they are produced in a lab. A helpful analogy is that while we can obtain naturally formed ice, we can also produce ice in a freezer; both are water, just formed differently.

Firstly, we rent our lab diamond HPHT machines by the hour, eliminating the need to purchase machines or pay markups from diamond wholesalers. Secondly, we operate as a fashion jewelry company and don't add the traditional markup common among fine jewelers. Moreover, unlike big international brands that has giant billboards, we focus on delivering value directly to you, without charging the costs of billboard ads to you.

Natural diamonds are priced based on rarity; the more flawless and colorless a diamond, the pricier it becomes. However, for lab-grown diamonds, where quality is controlled, we've adopted a fixed pricing model: $800AUD per carat, and $1000AUD per carat for our finest collection.

Much like natural diamonds, lab-grown diamonds lose 50%+ of their value in the second-hand market. They are meant to be worn, not locked away. Since lab-grown diamonds are machine-produced, they inherently lack the rarity of investment grade natural diamonds, which can appreciate in value over time. The value argument for lab grown diamond is that instead of losing thousands of dollars in the case of natural diamond, you lose hundreds of dollars. Either way, apart from investment grade large natural diamonds, most diamonds should not be seen as an investment asset.

Absolutely. Standard commercial diamond testers will identify lab-grown diamonds as genuine as they are optically, chemically, physically, and thermally identical to mined diamonds. To differentiate between lab and natural, specialized lab diamond detector is required. Alternatively, it is much easier to check the stone under magnification for its IGI laser inscription and verify details online, which is what we see a lot of local jewellers do.

Yes, feel free to contact us for our bespoke engagement ring service. We can source all available natural and lab diamonds globally and tailor your ring with precision 3D printing to match the chosen diamond's dimensions.

Every MYJS lab diamond is certified by the International Gemological Institute (IGI), the world's leading gemological body. Each diamond comes laser-inscribed with a unique code, verifiable on the official IGI website, accompanied by an IGI certificate. Lab-grown diamonds undergo grading just like natural diamonds, based on the four C's: Cut, Color, Carat, and Clarity.

We use High Temperature High Pressure (HPHT) machines. As the name suggests, these machines replicate the natural conditions under which diamonds form, enabling us to cultivate diamonds artificially. It's akin to making ice in a freezer, except we dial up the heat and pressure.

From an ethical standpoint, lab-grown diamonds are conflict-free as they are machine-produced, eliminating mining concerns. Regarding sustainability, we believe in giving you the choice. We don't build in a mandatory carbon offset fee but pass those savings to you. Whether you invest those savings in carbon offsets or a lovely dinner is entirely up to you.

We uphold rigorous quality standards. We believe that any lab diamond that's less than colorless, very slightly included, and doesn't have a triple excellent cut shouldn't be in the market. Therefore, our standard diamonds are D-E Color, VS1-VS2 Clarity, 3EX Cut, while our finest collection offers D Color, VVS1-VVS2 Clarity, 3EX Cut. We are also a firm believer that lab diamonds should never be sold without a certificate.

Moissanite is a distinct gem, typically less costly than diamonds. Originally a natural mineral, its limited natural availability led scientists to replicate it in labs. Though it may resemble a diamond, its color and hardness grades are lower.

Cubic zirconia, designed as a budget-friendly alternative to diamonds, is chemically distinct, softer, and lacks the diamond's signature brilliance. It's not a gemstone per se since it's not naturally occurring. Instead, it's synthesized from powdered zirconium and zirconium dioxide.
