Our commitment to you is quality assurance through expert and unbiased gemstone identification, analysis and grading.
Spectra provides precise scientific coloured gem testing and grading reports, using state-of-the-art equipment not widely available through other Australian gem laboratories. We are specialists in a wide range of popular gemstones including diamonds, sapphires, rubies, jadeites, emeralds, beryls and amethysts.
Our cutting-edge technology enables us to identify even the most inconspicuous treatments and imitations, and the level of detail in our Gem Reports is second-to-none. We will not only indicate whether your gem is natural, treated or synthetic, but also include any relevant information to substantiate our findings.
Boasting superior customer care and professionalism, our trade and consumer clientele alike are assured a seamless customer experience. We genuinely love what we do and go above and beyond to not only meet, but exceed expectations.
Spectra is privately owned and fully independent. We do not trade in jewellery or have corporate alliances with other companies, so there is no risk of a biased assessment. Our promise to you is a fair, honest and accurate assessment every time.
