Please note: This ring is made to order. Production time is about 1-3 weeks. This is a beautiful ring set with a high quality oval cut lab created white sapphire. The stones are faceted in a mixed brilliant cut to better simulate a natural sapphire. The setting is six prongs & lower profile. The sterling setting was made using deox sterling silver, a special sterling that uses alloys which are more tarnish resistant. Please note that more humid climates may cause any sterling to tarnish more quickly. The ring has a band width of 2mm. 8x6mm: 1.5 carats 9x7mm: 2.5 carats 10x8mm: 3.5 carats Metal options: 10k yellow gold 10k white gold 10k rose gold 14k yellow gold 14k white gold 14k rose gold (all gold options are solid gold) Regarding the sapphires I use: I only use lab created sapphires (corundum made in a lab). I never use simulated sapphires, ie, any material that is not corundum. Lab White Sapphire Oval Six Prong Ring
