EFFY® Lab Grown Sapphire (6-1/5 ct. t.w.) & Lab Grown Diamond (2-1/20 ct. t.w.) Halo 18" Pendant Necklace in 14k White Gold

The chain is super thin.. doesn’t look like white gold.. looks more like tarnished sterling silver. The pendant was beautiful though.. however I don’t understand the high price. Another brand sold at Macys is offering 5 carat lab sapphire with diamond necklace with a far better (thinker, shiny white gold) chain for six hundred. I don’t see any justification in this price more than two and a half grands.
