What does D color VVS1 mean when people talk about moissanite?

On testers: most standard diamond testers read moissanite as diamond. This is a known issue because both have high thermal conductivity. Testers marketed as 'moissanite detectors' exist but most jewelers do not carry them. A trained eye with a loupe can spot double refraction.

Top brands I would recommend: Charles and Colvard (the original, best consistency), Brilliant Earth (settings + ethically sourced), James Allen (good 3D previews), and Etsy sellers for custom vintage-style settings. Avoid no-name Alibaba listings unless you really know what you are doing.

I have a 2ct Forever One and I absolutely wear it every day. Gym, gardening, cooking, all of it. The stone has never chipped. Just take it off for heavy lifting so you do not bend the prongs.
