You’re looking at a 14k rose gold antique diamond and conch pearl estate ring. The LARGE oval shape conch pearl is whitish to very light pink in color. This undrilled NATURAL conch pearl is blemish free (NO imperfections, scratches or marks). It measures 10.2 mm x 7.0 mm x 5.8 mm and weighs 3.30 carats. You can easily see the vivid flame pattern on the surface of the pearl using a jewelers loupe. 
The 4 WHITE and CLEAN antique single cut diamonds are bezel set and weigh .08 carats total weight.
The top of the ring measures 13.0 mm x 10.6 mm. The bottom of the ring measures 4.8 mm wide. With the ring on your finger the conch pearl sits up 7.2 mm high. 
The ring weighs 3.4 grams and it’s a size 8. I can have the ring sized up or down a few sizes at NO EXTRA COST (FREE). Ring sizing takes about 3 to 4 days.
There are two hallmarks stamped on the outside of the ring shank, one of the hallmarks says “72” and the other one I can’t make out.
This ring is probably from the 1930’s and it could be Russian.
This VERY UNUSUAL antique rose gold diamond and conch pearl estate ring is GUARANTEED to be 100 PERCENT ALL ORIGINAL, AUTHENTIC, and GENUINE.
It is NOT a reproduction. 
Any dark or light areas you see on the ring, diamonds or conch pearl are reflections from my camera or the ring itself.
