I offer these three stone rings for your consideration. The size and shape of the gemstones can vary. The quality of the gemstones controls the cost. Medium shade blue sapphire will command a higher price than darker gemstones. Ceylon sapphires are typically higher in price. I concentrated my review to round sapphires approximately 5 mm. in diameter and oval cut sapphires 7x5 and 8x6 mm. I'll be happy to price other options as well. 
The mounting style 886 is available for both round and oval cut center stones. This ring with a 7 x 5 mm oval sapphire in the center and two 3 mm. diamonds would be approximately $2,500.00. The same ring with an 8 x 6 mm sapphire in the center would be approximately $3,000.00.
Most of the other styles with a round center depict a sapphire approximately 5 mm. in diameter. The price varies depending on the size of the side diamonds. Style 157 would be approximately $2,200.00. Style 088 would be approximately $1,800.00 Style 105 would be approximately $3,800.00. Style 567 would be approximately $3,000.00. Style 329 would be approximately $3,200.00.
I hope I have presented this information correctly. Whey you settle in on a style we can revisit cost again. We can vary the cost of any of the designs by varying the quality of the gemstones.
