This may be one of the prettiest pieces of glass I've ever been privileged to sell. Please look at all of the photos with care. I photographed the vase in front of a light as that is how the glassmaker made the glass, to have light shining through it.
The vase is a French cameo art glass rose bowl vase. The glassmaker is Daum Freres & Cie, or known as Daum Nancy. The age is circa 1904. The vase is signed twice, however the second signature is visible only in daylight with a magnifying glass, and it is there and quite obvious, visible not to just me but to others also; however the camera does not pick it up. Two signatures are important for the primary reason that it makes the vase 100% authentic, if one is not knowledgeable enough to tell with one glance at the first photo.
The vase is 4 ¼" high and 4 ¾" wide at the belly. The shape is one of a rose bowl on a round foot with a wide open mouth. The rim is round. The bottom is flat and smooth. There are a few scuff or rub marks on the overlay glass made by the tools, primarily on the edge of the foot. There are no chips, nicks, cracks or repairs.
I have a hard time telling how many layers of glass there are, so I will let the photos show everything. The color of the top layer is more of a teal, a blue-green. There is a body of water that is a lake with a shore line and trees going up the sides of the vase, with the leafy boughs at the top of the vase. Go back to the photos again in case you missed this but the vase is cut in such a high-end top notch excellent way that the shoreline is reflected in the waters of the lake, and the reflection is also cameo, and made lighter by cutting down another layer on the glass, with lines cut across to indicate rippling water over the reflections. If you didn't notice this by looking at the photos, go back and look another time, because there is yellow or orange in the glass where there is water, to show the sun shining off the water. There are other colors in the glass above the water to indicate clouds in the sky, and it is quite effective. Raised lines of teal glass were also left in the water to indicate more ripples.
The engraved signature is on the lower half of the vase, in the water. It is DAUM NANCY with the Cross of Lorraine to the left, and where the bottom of the "Y" curls down and crosses over the bottom of "C" to the left of the "Y". The second signature that is not visible in the photo is below the first signature. The second signature is one thin layer of glass up from the glass beneath it, therefore the same color on the same color, a tinier version of Daum Nancy with the Cross of Lorraine seen faintly. Both signatures are shown in the book "Daum Nancy III" by Katharina Buttiker, on page 176.
One last comment and that is Daum Nancy on their higher end cameo scenic glass did not use a glaring raised signature, which is a type of signature used on pieces with foliage motifs. On a high end piece of glass like this, the signature(s) will not be intrusive.
